     TECHNICAL FIELD 
     Embodiments of the present disclosure relate to managing information related to inventory and distribution, such as the inventory and distribution of draft (draught) beer. Further embodiments of the present inventions relate to monitoring of draft beer and other bulk beverage inventories, and to related data analysis, including automated ordering, prompting for ordering, and mobile marketing. 
     BACKGROUND 
     Establishments such as restaurants and bars frequently receive products consumed by customers, such as beverages, from distributors. When an establishment runs low on certain products, the establishment typically contacts the distributor to resupply the establishment&#39;s stock of products. However, this process can be time consuming, especially when it is difficult for the establishment to ascertain the quantity of certain products, such as when those products are supplied in bulk, such as in kegs. It was realized by the inventors of the current disclosure that improvements in the supply chain for certain products, such as beer in kegs, are needed. Certain features of the present disclosure address these and other needs and provide other important advantages. 
     SUMMARY

     DETAILED DESCRIPTION 
     For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to one or more embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended; any alterations and further modifications of the described or illustrated embodiments, and any further applications of the principles of the disclosure as illustrated herein are contemplated as would normally occur to one skilled in the art to which the disclosure relates. At least one embodiment of the disclosure is shown in great detail, although it will be apparent to those skilled in the relevant art that some features or some combinations of features may not be shown for the sake of clarity. 
     Any reference to “invention” within this document is a reference to an embodiment of a family of inventions, with no single embodiment including features that are necessarily included in all embodiments, unless otherwise stated. Furthermore, although there may be references to “advantages” provided by some embodiments, other embodiments may not include those same advantages, or may include different advantages. Any advantages described herein are not to be construed as limiting to any of the claims. 
     Specific quantities (spatial dimensions, temperatures, pressures, times, force, resistance, current, voltage, concentrations, wavelengths, frequencies, heat transfer coefficients, dimensionless parameters, etc.) may be used explicitly or implicitly herein, such specific quantities are presented as examples only and are approximate values unless otherwise indicated. Discussions pertaining to specific compositions of matter, if present, are presented as examples only and do not limit the applicability of other compositions of matter, especially other compositions of matter with similar properties, unless otherwise indicated. 
     At least one embodiment of the present disclosure includes a system/method for measuring the amount of liquid in a portable liquid container and wirelessly communicating that information to a database in order to automatically establish/maintain an inventory of the amount of fluid in each container. Particular embodiments include detecting the level of beer in a keg and relaying that information to a central database that can be used, for example, by a distributor to know when certain kegs need to be replenished. 
     At least one embodiment includes: a sensor for detecting the fluid level; an identification device that identifies the brand/type of fluid (beer); a transmitter/link that wirelessly connects the sensor and ID device to a database; and a database for maintaining the information (likely connected to a wireless network). 
     Detecting the level of fluid (beer) in each individual container (keg) may be accomplished in at least two ways. One is a weight sensor attached to the bottom of the portable keg. Another is a sensor that determines the fluid level by generating and evaluating a signal directed to the container. One example is a transmitter that transmits energy into the container. Another example is a transmitter that reflects energy (e.g., sound waves) off the surface of the liquid 
     Identifying the brand/type of fluid (beer) in each individual container (keg) may be accomplished in at least two ways. One is to encode information related to the brand/type of liquid (beer) in each container (keg) to the fluid level sensor attached to each keg. Another is to use a device separate from the fluid level sensor and encoded this separate device with the brand/type of beer in the keg. This separate identification device can be attached to each container (such as to the hand grip holes in a keg) using, e.g., a bracket, zip tie, clip, bayonet fitting, etc. 
     The transmitter can receive information from both the fluid level sensor and the identification device and can wirelessly relay this information (e.g., using established wireless networks) to a database. In one embodiment, the transmitter is included with the fluid level sensor; however, other variations include a transmitter included with the identification device or a transmitter that is separate from both the fluid level sensor and the identification device. 
     At least one embodiment utilizes a combined fluid level sensor and transmitter with a separate identification device. The identification device may be a wireless communication device (such as an RFID device, which may take the form of an RFID tag and/or a bar code display), or may require physical connection (such as a thumb drive or the like). In use, a delivery person can arrive at a bar/restaurant with a keg that has an RFID device attached identifying the brand/type of beer (or other characteristic of the liquid in the container to which the RFID device is associated) in the keg. A combined fluid level sensor and transmitter (which can be generic and used with any keg) is attached to the container (keg), which may be accomplished prior to delivery to the customer, and the combined sensor/transmitter is paired with the RFID device. Once paired, the sensor/transmitter can transmit information related to the amount of beer and the brand/type of beer (or other characteristic(s) of the liquid) in the keg to the database. Multiple kegs and sensor/transmitters can be monitored and information about the kegs can be maintained, interpreted, and disseminated in a variety of ways that may be useful to brewers, distributors, sales establishments, and/or customers. See, e.g.,  FIGS. 10-12 and 14 . 
     A user of the database can be able to use real-time information about the kegs in a variety of ways, such as enabling the distributor to automatically deliver fresh kegs when needed or to provide real-time information to consumers so the consumer can determine which bars/restaurants have their preferred beverage in stock. Various embodiments include database interfaces for the restaurant owner, customers, distributors and beer manufacturers that may be used in a variety of combinations to facilitate the efficient delivery of liquid in bulk containers for consumption. 
     At least one embodiment of the present disclosure uses on-keg monitoring devices to keep track of substantially real-time levels of draft beer in inventories of on-premise beer retailers. Data collector(s) at each site periodically transmit the data to a centralized data storage and processing facility. Alerts are sent to key personnel when it is time to place another order, and supply chain mechanisms leverage the data for efficient resource planning and movement at all stages. Consumers are able to find favorite beers by accessing the inventory data through a mobile app, and other uses are made of the collected data. 
     The draft beer industry employs re-usable aluminum kegs to distribute draft beer. The kegs are simple aluminum vessels that can be filled with beer, pressurized, and then the beer flows out of a top-mounted valve/spout. The keg typically embodies no technology beyond a simple pressure valve/spout on the top. 
     Kegs are often designed with a spherical round bottom that is surrounded or collared with a round aluminum sheath that allows the keg to sit upright and level. This collar on the bottom of the keg, combined with the spherical round bottom, creates a constructed void or space under the keg. All kegs have this empty space under the main container portion. 
     At least one embodiment of the present disclosure includes a sensor and transmitter (which may be referred to as a sensor/transmitter) that attaches to the bottom of the keg, such as fitting in this space under the bottom of the keg. In one embodiment, illustrated in  FIGS. 1-3 , the sensor  100  is generally a pressure sensor, which in at least one embodiment is an analog electronic device that converts weight into an analog value calibrated to the weight of a full keg. When the sensor  100  is mounted to the bottom of the keg, the sensor weight element  108  rests on the floor. In some use scenarios, kegs are stacked on top of each other. In such situations, the system vendor can supply a rigid, hard plastic mat (not shown) that can fit on the top of a keg to provide a hard, level surface for the keg sensor/transmitter on the next layer up to sit on. In this stacking scenario, the sensors on the bottom kegs can be adjusted to account for there being more than one keg resting on top of the sensor weight element  108 , such as by transferring weight information to/from the kegs above. In the illustrated embodiment, sensor  100  has a circular center portion with connection brackets extending outward in a generally star-shaped configuration, although other shapes are contemplated. 
     The sensor  100  registers pressure from the weight of the keg. In the case of a full keg that has a maximum volume and weight, the sensor registers a maximum analog value, which is converted in the present embodiment into a digital value by an analog-to-digital converter (ADC) onboard the microcontroller chip in the sensor/transmitter unit. In some embodiments, the conversion uses an 8-bit value, while in others, another range of digital outputs (such as 0-20) is used. Using this latter form as an example, as the keg is depleted, the value changes from 20 to 19, 18, 17, etc. all the way down to 0 (zero), which is the value corresponding to the weight of an empty keg. The keg sensor/transmitter electronics communicate the weight value of 0-20 to the keg transmitter. The keg transmitter may be housed in the bottom of the keg and may be connected by wire (or wireless) to the keg sensor. In the present embodiment, the keg transmitter communicates with the local uplink/gateway (such as using ZigBee and/or Bluetooth protocols), which communicates with a larger network (such as a cellular telephone network or a mesh network). Alternate embodiments utilize alternate wireless data transmission technologies as will occur to those skilled in the art in view of the present disclosure. In some embodiments, the keg sensor can remain asleep and wake up periodically to receive an signal related to the current weight of the keg, communicate with the network (e.g., the cellular network, which may be via the local uplink/gateway) and transfer data to and/or from a database (which may take approximately 10-20 seconds in some embodiments), then go back to sleep. In one embodiment, the keg sensor wakes up and communicates with the network once every hour. In other embodiments, the sensor will wake up more or less frequently depending on the time of day or the day of the week/year. In still other embodiments, the sensor wakes up based on a schedule received from a database, which may be adjusted by the database. For example, if an algorithm evaluating data form a database determines that beer A is selling quickly and beer B is not selling quickly, a command can be sent through the network to one or more sensors associated with beer A (e.g., through a cellular network, which may be sent to the sensor via a local uplink/gateway) instructing the one or more sensors associated with beer A to wake up and communicate with the database every 20 minutes and/or a command can be sent through the network to one or more sensors associated with beer B instructing the one or more sensors associated with beer B to wake up and communicate with the database every 2 hours. 
     In at least one embodiment, the keg transmitter may also have a flash memory that has been preprogrammed with several software parameters. One of these parameters can be a Serial Number corresponding to the individual keg sensor/transmitter. That is, each and every keg sensor Transmitter can have its own unique Serial Number that is programmed into the software when the unit is manufactured. In addition to the Serial Number, the software version number may be pre-programmed. The keg transmitter software may also be programmed with certain functions and intelligence. In this embodiment, the software may be programmed at the factory to perform various functions, including waking itself up every X number of hours and transmitting a signal via a wireless network (e.g., ZigBee and/or Bluetooth) to check whether it is in range of an uplink/gateway. When the transmitter is shipped to an equipped warehouse, the keg transmitter can first wake up and connect with an uplink/gateway. At that point, the keg transmitter can begin to check for an uplink/gateway every hour. 
     Depicted in  FIGS. 4-6  is a sensor  200  according to another embodiment of the present disclosure. Sensor  200  is configured and adapted to attach to the bottom of a large beverage container (such as a beer keg) and sense the weight of the container. Sensor  200  includes one or more fasteners  202  that prevent sensor  200  from falling off the keg when the keg is lifted off the support surface. Sensor  200  also includes one or more abutment surfaces  203  that abut the bottom surface of the keg and permit sensor  200  and support the keg keeping it slightly elevated above the support surface. In the illustrated embodiment, sensor  200  is doughnut-shaped (toroidal) being generally circular with a circular aperture in the center, although other shapes are contemplated. 
     When installed, sensor  200  attaches inside the cavity (false bottom) on the underside of the keg (see, e.g.,  FIGS. 6A and 6B ) and does not extend to the outside surface of the keg, and may be sufficiently removed from the bottom edge of the keg (as depicted in  FIG. 6B ) so that sensor  200  does not contact the support surface and is not damaged when the keg is tipped onto its bottom edge/lip and rolled/rotated as is commonly done when moving kegs. In the illustrated embodiment, sensor  200  includes five fasteners  202  that clip to the inside of the lip that forms the bottom of the keg. See e.g.,  FIGS. 6A and 6B . In at least one embodiment, fasteners  202  are configured and adapted to allow a user to attach sensor  200  to a keg and detach sensor  200  from a keg using only the user&#39;s hands. In  FIG. 6B  the sensor is depicted as flexing and snapping firmly into place on the rolled lip, although other embodiments affix to the keg is different, yet secure, fashions. 
     Sensor  200  further includes a receiver  204  that receives data from an electronic device (typically attached to a keg, such as an RFID device) containing information about a characteristic of the fluid within the keg. (As used herein, a characteristic of the fluid within a keg includes, but is not limited to, the brand-name, type, manufacture date, or other characteristic about the fluid a distributor, retail seller, or consumer would be concerned with). Sensor  200  further includes a transmitter  206  that communicates with a wireless network and can transmit information concerning a characteristic of the fluid in the keg to which sensor  200  is attached (received from an RFID device  220  associated with the keg via receiver  204 ) and information about the weight of the keg to the wireless network. (See, e.g.,  FIG. 14 ). 
     In alternate embodiments receiver  204  is both a receiver and a transmitter capable of two-way communication with the electronic device (e.g., RFID device) associated with the keg containing information about the liquid contained within the keg. 
     In alternate embodiments transmitter  206  is a receiver and a transmitter capable of two-way communication with the wireless network. 
     Sensor  200  further includes one or more weight sensors  208  that sense the weight of the keg (such as by measuring the pressure exerted on the weight sensor  208  by a support surface upon which sensor  200  and the keg are placed). Four weight sensors  208  are depicted in the embodiment represented by  FIGS. 4-6 . In embodiments with fewer than three weight sensors, additional supports can be utilized so that the keg to which sensor  200  is attached is stable and will not easily tip when resting on a support surface. 
     Sensor  200  can include a battery compartment  210  for housing a battery to provide electrical power to the various components of sensor  200 . 
     Sensor  200  may also include an optional RFID pairing capability in which a user can pair sensor  200  with an RFID device  220  (e.g., an RFID tag) containing information about the liquid in the container to which sensor  200  is (or will be) attached. As an example, the pairing system may include a pairing button  212  that a user depresses when in proximity to the RFID device with information related to the liquid in the keg and transfer this information from the RFID device to sensor  200 . Sensor  200  can then transmit this information related to the liquid in the keg to a wireless network. An optional pairing light  214  may be included as an indication to the user that sensor  200  has been paired with the RFID device.  FIG. 13  depicts a user pairing a sensor to an RFID device attached to a hand hold aperture of a keg then installing the paired sensor on the keg. 
     In some embodiments of the present invention, the pairing device and RFID devices are configured for short range use to avoid interference with other RFID devices that may be stored nearby. For example, in one embodiment, the pairing system and RFID device have a maximum pairing range of approximately 15 feet. In other embodiments, the pairing system and RFID device have a maximum pairing range of approximately five (5) feet. In yet other embodiments, the pairing system and RFID device have a maximum pairing range of approximately two (2) feet. In still further embodiments, the pairing system and RFID device have a maximum pairing range of approximately one (1) foot. The short range pairing feature may have particular advantages in environments where there are multiple kegs with a sensor  200  and RFID device attached to each keg. (See, e.g.,  FIG. 14 ). 
     In at least one embodiment, each RFID device is programmed with a unique serial number and unique attributes of the liquid contained in the keg can be assigned to the tag via a wireless network and the attributes associated with a particular RFID device may be manipulated through the wireless network without requiring use of an RFID writer in close proximity to the RFID device. 
     The sensors and sensor/transmitters disclosed herein are constructed of material sufficiently strong to carry the large weight loads of a full keg and capable of operating at low temperatures, such as would be encountered in a refrigerated location, and may include various types of plastics, composites, metals, and/or alloys. 
     The keg sensor/transmitters may be sent in quantity to the beer distributor&#39;s warehouse. At the beer distributor&#39;s warehouse, the keg sensor/transmitter may be installed on a keg. For example, in one embodiment, the keg sensor/transmitter is mounted on the bottom of the keg in the recessed cavity that is created where the convex portion of the keg comes in contact with the outer edge. The keg has a molded lip on the outer portion of the keg that allows a tongue-and-grove fitting to be pushed into place. To achieve the fitting of the keg sensor/transmitter to the bottom of the keg, one may use a suitable keg installer, which will now be described in view of  FIG. 7 . 
     The keg installer  250  in this embodiment is a fabricated aluminum and steel platform consisting of three large pieces: the inbound ramp  252 , the Plateau  254 , and the outbound ramp  256 . The inbound ramp  252  is approximately four feet wide and six feet long. The inbound ramp  252  has a total of approximately 20 rubber rollers  258  with each roller approximately 4 inches in width. The rollers  258  are mounted on aluminum rails spaced the width of a beer keg. There is a hollow space between the rails. There are 10 rollers on the left rail and 10 rollers on the right rail. The beginning part of the inbound ramp  252  uses small rollers that start at floor level. The inbound ramp  252  is on an incline starting at floor level then rising to approximately 5 inches off of the ground. 
     In use, a beer distributor warehouse worker moves a full keg of beer to the beginning of the inbound ramp  252  and positions the keg in the middle of the ramp. The worker then slightly tips the keg and scoots it forward so the keg rests on the first rubber rollers of the inbound ramp  252 . The worker then pushes the keg up the inbound ramp  252  as it rolls on the rubber rollers. 
     The inbound ramp  252  in this embodiment is bolted directly to the Plateau portion of the keg Installer. The Plateau has approximately 12 rollers-6 rollers on the left rail and 6 rollers on the right rail. The rails and rollers in this embodiment match up exactly in alignment with the rails and rollers on the inbound ramp  252 . 
     The outbound ramp  256  in this embodiment is approximately four feet wide and six feet long and is bolted directly to the Plateau portion of the keg installer  250 . The outbound ramp  256  has approximately 20 rollers with each roller approximately 4 inches in width. There are 10 rollers on the left rail and 10 rollers on the right rail. There is an open space between the rails. The rails and rollers match up exactly in alignment with the rails and rollers on the Plateau. The outbound ramp  256  is on a decline starting at approximately 5 inches off of the ground going down to floor level. 
     In the open space between the rails on the outbound ramp  256  is a keg sensor/transmitter Installation device. A keg sensor/transmitter that is ready to be installed on to a keg is placed into the platform device between the rails. As the keg descends the outbound ramp  256  the weight of the keg pushes down on the installation device platform triggering a hydraulic lever. That lever flexes the keg sensor/transmitter housing and pushes the keg sensor/transmitter housing into the cavity in the bottom of the keg. The hydraulic lever then un-flexes the keg sensor/transmitter housing, and the housing snaps into place in the keg bottom cavity. 
     The warehouse worker then continues to move the keg down the outbound ramp  256  to floor level. The keg now has the keg sensor/transmitter installed, and it is ready to be delivered to the retailer. The warehouse worker now can put a new keg sensor/transmitter into the keg installer  250  and repeat the process. 
     Once a keg is empty, it can be picked up by the beer distributor delivery driver to be returned to the beer distributor warehouse. Since the keg is now empty, the keg is very light and can be easily picked up and turned over by the delivery driver or warehouse employee. The keg sensor/transmitter can have the bar code or QR code assigned to it in the distributor&#39;s inventory system. The keg sensor/transmitter in this embodiment can be taken off of the keg by hand and can be put in one of, e.g., four bins. 
     Bin #1: The sensor is good and can be re-used. It is put in a bin labeled with the beer brand and type. 
     Bin #2: The beer brand and type is no longer in distributor inventory. The warehouse employee uses the SaaS Software to re-assign the keg sensor/transmitter&#39;s individual serial number to the SKU associated with another beer brand and type. 
     Bin #3: The bar code is faded and needs to be replaced. 
     Bin #4: The battery life of the sensor has exceeded normal life, and the sensor needs to be returned to the system vendor. 
     At system initialization, the SaaS database can be populated with all of the current beer brand and type SKUs. As time goes by, however, new beer SKUs may appear. Each beer distributor warehouse and accounting employee on the overall system can enter in new beer brands and types with their corresponding SKUs. These new SKUs can be made available to all beer distributor users across the entire overall system. That is, the process of updating new SKU&#39;s into the SaaS system can be crowdsourced. 
     The keg installer  250  in the embodiment just described is made of three pieces—the inbound ramp  252 , the Plateau, and the outbound ramp  256 —so that it can be easily assembled and disassembled for shipping to beer distributor warehouses. In alternative embodiments and situations, the keg installer  250  can be used with the Plateau and the outbound ramp  256 , eliminating the inbound ramp  252 . The option is up to the beer distributor warehouse. By removing the inbound ramp  252 , a forklift can be driven up directly to the Plateau portion of the Installer, and the keg can be moved off of the forklift onto the Plateau to complete the installation. 
     The keg installer  250  is both a mechanical installer of the keg sensor/transmitter plus is a point at which a warehouse worker can check to be sure that the keg on which he is installing the keg sensor/transmitter matches the Order Pick List. As shown in  FIG. 7 , a small computer and monitor can be mounted to the keg installer  250 . In addition, an uplink/gateway can be mounted on the keg installer  250 . This uplink/gateway can have a desensitized receive antenna so that it only receives the keg sensor/transmitter that is being installed onto the keg. As the worker rolls the keg through the installation process, they can perform a visual check to make sure that the content of the keg they have in front of them on the Installer matches what the SasS system says it should be, plus it matches the Order Pick List. That Order Pick List in some embodiments can be a piece of paper with the order written on it, while in other embodiments the SaaS system can have an EDI (Electronic Data Interface) connection to the beer distributor&#39;s inventory system. 
     So, for example, the keg that is being rolled onto the Installer may have a paper keg collar. A paper keg collar clipped on a keg&#39;s top valve is a common way of identifying the contents of a keg. The worker looks at the keg collar and sees that the beer in the keg is identified as “Bell&#39;s Founder&#39;s Ale”. As the worker installs the keg sensor/transmitter the unit transmits its serial number as KS1234 thru the uplink/gateway. The SaaS application displays on the computer monitor that the sensor is associated to the SKU for “Bell&#39;s Founder&#39;s Ale,” and that confirms the correct Sensor Transmitter is being put on the correct keg. The SaaS Software also displays the Order Pick List and the warehouse worker can confirm that it is the correct keg/product to go out. 
     The top-mounted keg sensor/transmitter shown in  FIG. 8  is a sound wave-based unit that can be mounted on the top of a keg in some embodiments of the present system, and can be mounted on the bottom or sides of the keg in other embodiments. The top-mounted keg sensor/transmitter may be mounted with its bottom surface sensor side flush and flat with the top surface of the aluminum keg. To accomplish that flush mounting, a top-mounted keg bracket may be used, such as one made out of aluminum and/or steel. The bracket may be approximately 6 inches in length. At the top of the bracket there can be a “Y”-shaped fork, and at the bottom of the bracket there can be a “T”-shaped end. In the middle can be the actual keg sensor/transmitter, which is approximately 3 inches square in one embodiment. The top-mounted bracket can be designed with a pressure spring, hand lever, and lock. The bracket may be placed on the top of the keg with the “Y” shape up against the keg valve. A branch of the “Y” sits on either side of the valve. The “T”-shaped end can rest in the outer edge of the top of the keg. The bracket can be put into place and the hand lever pushed down, which creates pressure on the spring and flexes out and bows the bracket out and down. The bracket flexes out the “Y” and the “T,” and the hand lever locks into place, securing the bracket to the keg with equal and opposing force on the “Y” at the valve and the “T” at the edge of the keg top. The force also pushes the keg sensor/transmitter firmly onto the top of the keg with the downward force. The action of the bracket in this embodiment is similar to the concept behind a snow ski binding. The bracket can be removed by unlocking the lever, the force is removed, and the bracket is free. 
     The majority of beer kegs used by craft brewers in the county are leased from one of two keg leasing companies. In certain embodiments, agreements with keg leasing companies and with keg manufacturers can allow a more permanent mount to be included on kegs for the top-mounted keg sensor/transmitter. 
     The design form that may be used for the top-mounted sensor is similar to a large hockey puck. The flat side of the “puck” can sit on top of the keg, pressed against the top surface. In some systems, the data vendor works with keg manufacturers and keg-leasing companies to spot-weld an aluminum bracket to the top of each keg. The top-mounted keg sensor/transmitter would then be attached to the top of the keg by attaching it to this welded bracket. In some embodiments, this design would be very similar to a bayonet-mount camera lens. The round-shaped top-mounted keg sensor/transmitter would have a three-pronged male bayonet mount. The bracket mounted on the top of the keg would have a recessed female bayonet mount. The keg sensor/transmitter would be placed on the top of the mount, and with a one-quarter clockwise twist, the keg sensor/transmitter mount would be securely mounted onto the keg. 
     The uplink/gateway in various embodiments is a self-contained unit that can be mounted on the wall, such as outside of the beer cooler, of an on-premises retailer (bar or restaurant) that contracted with their local beer distributor to use the service described herein. The uplink/gateway can be a moisture-resistant, shock-resistant plastic box that contains radio receivers, computer hardware, computer software, and radio transmitters. Each uplink/gateway can have its own unique serial number that is embedded into the uplink/gateway software. An uplink/gateway  289  according to at least one embodiment is depicted in  FIG. 9 . 
     The uplink/gateway consists of two major areas and functions in some embodiment. The hardware radio receiver and software stack receives the data transmissions from each keg sensor/transmitter within its range, which are typically the keg sensor/transmitter(s) in the nearby cooler. The receiver receives the data, organizes the data, and tags the data with information unique to the individual uplink/gateway including the unit&#39;s unique serial number and version number. Once the receiver and software stack has organized that data, it is sent to a gateway, e.g., a CDMA cell phone gateway. This overall system is illustrated in  FIG. 10A . Information about the contents in each keg may also be communicated to the sensor/transmitter using a separate data storage device (such as an RFID device) attached to the keg, which is paired with and transfers information to the sensor/transmitter for uplink to the larger network. 
     The CDMA uplink/gateway is a transmitter/receiver that contains both radio hardware and software. The CDMA uplink/gateway in some embodiments can be constructed with specifications provided by a wireless carrier partner, such as Verizon Communications. (In other embodiments, of course, GSM and/or other wireless data transmission protocols are used instead of or in addition to CDMA.) The uplink/gateway can join the carrier&#39;s data service by connecting the closest cell phone tower to the on-premise retailer where the uplink/gateway has been placed. The uplink/gateway relays the data from the keg sensor/transmitter(s) that has been collected by the receiver. The CDMA uplink/gateway can communicate with the carrier&#39;s network to determine the longitude and latitude of the Gateway and can transmit that data, its software version number, and the data collected by the receiver to software, e.g., SaaS Software. 
     In some embodiments, after the keg sensor/transmitter is attached to the keg, the keg is delivered to the on-premise retailer, a bar or restaurant that sells draft beer. At the retailer the keg is placed in the retailer&#39;s keg cooler. Once the keg is placed in the cooler, it is now in radio range to join a network that includes the keg sensor/transmitter of each keg in the cooler as well as the uplink/gateway. As soon as the keg is placed into the cooler, the keg sensor/transmitter may begin transmitting data. The data transmitted can include the weight parameter (e.g., 0-20) from the sensor, the Sensor Transmitter Serial Number (e.g., #KS1234), the version number of the software (e.g., ver.0), and/or keg ID information (e.g., information about the fluid in a keg received from the RFID device associated with the keg). This collection of data is transmitted to the uplink/gateway. The uplink/gateway acts as a conductor collecting data from all keg sensor/transmitters in the cooler and maintains its own serial number (#UG5678) and its own location longitude and latitude data (e.g., latitude: 39.77572 longitude: −86.15569). The uplink/gateway collects Sensor Data then adds its own data that is transmitted via the carrier&#39;s CDMA cell phone data network to the SaaS software. So an example data feed would look like: 
     keg sensor/transmitter sends a data string: 
     keg_sensor_serial=KS1234&amp;;weight_parameter=10&amp;;keg_sensor_version=1.0&amp;;gatewav_version=1.0&amp;;keg_rfid=1234 
     This data string is received by the uplink/gateway, and the uplink/gateway embedded software adds its data. The combined data string in this example would then be: 
     uplink_gateway_serial=UG1234&amp;;long=39.77572&amp;;lat=−86.15569&amp;;=5&amp;; keg_sensor_serial=KS1234&amp;;weight_parameter=10&amp;; keg_sensor_version=1.0&amp;; gateway_version=1.0&amp;;keg_rfid=1234 
     When there are multiple keg sensor/transmitters in a cooler, the combined data string would look like: 
     uplink_gateway_serial=UG1234&amp;;long=39.77572&amp;;lat=−86.15569&amp;;=5&amp;;keg_sensor_serial=KS1234&amp;;weight_parameter=10&amp;;keg_sensor_version=1.0 &amp;;gateway_version=1.0&amp;;keg_rfid=1234;keg_sensor_serial=KS5678&amp;;weight_parameter=4&amp;;keg_sensor_version=1.0&amp;;gateway_version=1.0&amp;;keg_rfid=5678;keg_sensor_serial=KS91011&amp;;weight_parameter=3&amp;;keg_sensor_version=1.0&amp;;gateway_version=1.0;keg_rfid=91011 
     The data is collected and sent by the uplink/gateway through the CDMA cell data network, then over the Internet to the SaaS software. Upon receipt by the SaaS software, the collected data from the keg sensor/transmitter can be correlated and saved in the database in several different ways. 
     The keg sensor/transmitter Serial Number may be correlated to an SKU that matches the beer brand and type. The correlation between the Serial Number and SKU has been pre-programmed into the SaaS Database or via the keg RFID device. For example, if Serial Numbers KS0000 through KS1234 have been assigned SKU998877665544, which is beer brand and type “Bell&#39;s Founder&#39;s Ale,” then when the SaaS software receives data from Keg Sensor Serial Number KS1234, the SaaS software writes the data into the database as being associated with that SKU, beer brand and type “Bell&#39;s Founder&#39;s Ale.” The SaaS software can have programmed intelligence that also converts the weight parameter into a percentage of volume. So, for example, if the keg sensor sends a weight measurement of 10 on a scale of 0-20, that means the keg is half-weight, thus half-full. The SaaS software converts weight to volume. 20 is full, 100%. 0 is empty, 0%. The scale of 0-20 is, therefore, converted by the SaaS software to 20 steps of volume in percentage units. 
     The uplink/gateway can add its data to show the location of not only the Uplink Gateway, but also the location of the keg sensor/transmitters that it is collecting data from in its coolers. As an example, assume that in the SaaS software the uplink/gateway serial number UG1234 has been assigned to the location of retailer “Scotty&#39;s Bar and Restaurant.” So when the transmission of data from a keg sensor/transmitter is made through the uplink/gateway, the location of the keg is known. So, for example, a keg sensor/transmitter KS1234 with weight parameter  10  may be transmitted to the SaaS software thru uplink/gateway UG1234. The SaaS Software has presumably already stored the location data of the uplink/gateway, the association of the keg sensor/transmitter to SKU Beer Type, and the conversion of weight to volume. When each transmission of data occurs in this embodiment, the SaaS database assigns a date and time stamp converted from UTC (Coordinated Universal Time) to local time. So when the transmission of data occurs, and the SaaS software receives the data, the data is converted to report that the particular keg of “Bell&#39;s Founder&#39;s Ale” currently located at “Scotty&#39;s Bar and Restaurant” is 50% full at 10 PM today. 
     KS1234=Bell&#39;s Founder&#39;s Ale 
     UG1234=Scotty&#39;s Bar and Restaurant 
     Volume=50% (Weight value of 10 converted to %) 
     Date-Time=3.15.13 10:00 PM 
     The embedded software in the keg sensor/transmitter can have intelligence built in. For example, it can regulate the time factor of how often the data is transmitted from the keg sensor/transmitter to the uplink/gateway. In one example, the software is set to send data every hour time period, but that time period can be changed. The keg sensor/transmitter software has the intelligence to only transmit data if the weight value has changed. In the future, the keg sensor/transmitter can also have the ability to transmit the ambient temperature around the keg (cooler temp) and the keg sensor&#39;s remaining battery life as a percentage. 
     One design of the keg sensor/transmitter uses short-range radio technology (e.g., ZigBee and/or Bluetooth) to connect and send data thru the uplink/gateway. An alternative design, an example of which is illustrated in  FIG. 10B , eliminates the uplink/gateway step by providing the keg sensor/transmitter itself a direct CDMA cell data connection so that the keg sensor/transmitter can transmit its data directly to the SaaS Software. 
     Still further versions of the Keg/Sensor Transmitter can change from the bottom-mounted weight sensor, to a top-mounted sensor. The top-mounted keg sensor/transmitter uses sound wave technology to send a sound wave through the top of the keg. The sound wave can bounce off the top of the liquid (beer) and return to the keg sensor/transmitter. The interval of time between the time at which the sound wave was sent and the time at which the return sound wave was received would be measured. This measurement would be transmitted to the SaaS Software, which can convert the time interval into a percentage of volume of the beer remaining. A short time interval would mean a fuller keg. A longer time would mean an emptier keg. 
     Now that we have the basic keg volume, date time, and location data coming from the keg sensor/transmitter through the uplink/gateway into the SaaS Software database, we can talk about how we act upon the gathered data.  FIG. 11  provides a schematic illustration of some such actions, while others will occur to those skilled in the art in view of this disclosure. 
     There are several levels of use of the gathered data that in the illustrated embodiments is now in the SaaS Software. The SaaS Software can be set up with individual accounts for each Bar and Restaurant retailer using the service. A representative of the retailer can set up accounts for each individual in their organization who interacts with keg beer. The setup process can include adding each individual&#39;s smart phone/mobile phone number. The representative can set up rules based on their organization&#39;s individual needs. One function in the day-to-day operation can be to be able to have an insight into the current status of their keg beer inventory. The representative can log onto the SaaS software, then review current inventory and set rules for alerts based on depletion rates of keg beer. In various embodiments, these alerts can take on the form of SMS text sent to mobile phones, popup push alerts that are part of iPhone, Android and other smart phone formats, emails sent out, recorded voice alerts sent to phones, and other forms that will occur to those skilled in the relevant technologies. The alerts can be sent to retail workers based on their current location. The system software can take advantage of the location-based service built into each smart phone. The worker may only get alerts if they are in the geographical longitude and latitude area that has already been defined in the SaaS database by the recording of the uplink/gateway assigned to their place of work. This can assure that workers will not get alerts during their off-shift hours. A manager who would like to get alerts when they are off-site from their retail location can override this function. 
     In other embodiments, alerts take the form of visual flashing lights and integration into other software in the restaurant including, but not limited to, POS terminals (Point of Sale, electronic “Cash Registers”). 
     The retail representative can assign a value to certain beer brands and types and customize alert based on the value of the beer, that is, the importance of not running out of that beer. For example, the retailer might not value the “Stroh&#39;s Light” beer as much as the “Bell&#39;s Founder&#39;s Ale.” So the retailer representative might set up the SaaS software to automatically alert the designated retailer representative when the Stroh&#39;s reaches 10% remaining, while the more valuable Bell&#39;s would automatically alert when the remaining beer registers in the SaaS system as 40% remaining. In alternative embodiments, patterns in the rate of consumption of each product are taken into account, and depletion events are forecasted so that alerts can be raised and orders can be placed “just in time.” 
     When an alert is sent to the retailer, there can be multiple paths (e.g., four paths) that they can use to re-order the keg that is running low. If the alert comes to the retailer&#39;s phone, they can re-order by sending an SMS text message directly to their beer distributor sales rep, or by sending an SMS text message to an SMS gateway that is controlled by the system vendor and connected by EDI (Electronic Data Interchange) into the beer distributor&#39;s ordering system. Another option can be to activate a button in the user interface to initiate a voice call to their beer distributor&#39;s sales rep. There can also be iPhone and Android smartphone applications that have a re-ordering function built-in, connecting by EDI to the beer distributor&#39;s ordering system. The interface of the smartphone application could have a visual alert with the button option “re-order now,” which the retailer can choose. 
     In some embodiments, the retailer can set their account to have the SaaS software automatically submit re-orders on kegs based on rules they set for each brand and type of beer. For example they can set a rule to automatically re-order “Bell&#39;s Founder&#39;s Ale” if the depletion level has dropped below 40% and the day of the week is Wednesday thru Friday. 
     Retailers can have standard reports accessible to them via the SaaS web-based platform or mobile app. These reports can include current and past inventory reports, current and past keg depletion rates, and other reports key to their operation. 
     Beer distributor sales representatives can see all of their accounts and the current state of each retailer&#39;s keg inventory. The sales representative can see when alerts on low kegs were sent out to retailers, who the alert was sent out to, and what action (if any) was taken by the retailer to re-order the depleting, or depleted, keg. The management of the beer distributor can have a near-real-time view of current beer depletion across all of their retail accounts. This near-real-time data can allow them to more efficiently control their inventory of kegs in their warehouse based on trends in usage. 
     The near-real-time data that the presently disclosed process may be collecting can also be used by breweries to determine what beers are being sold and at what rate. They then can adjust what beers they are planning to brew and in what quantity they brew the beer. In the case of large breweries, they can adjust the purchasing of the ingredients of beer components on the grain futures market. The system vendor can also sell data to marketing data firms who track trends in consumer consumption. 
     As will be appreciated by those skilled in the art, and API (Application Programming Interface) can be developed to allow other applications to access system data for real time software applications. 
     An example would be a consumer “Beer Finder” smartphone application. The smartphone application would integrate into the operation system of the smartphone and be able to find the phone&#39;s exact location in longitude and latitude. The app would then send a query the SaaS Database thru the API to find out the closest keg sensor/transmitter and uplink/gateway to the person using the smartphone app. Near real time data of volume of a brand and type of a beer as well as its longitude and latitude location has already been recorded from the keg sensor/transmitter and uplink/gateway. So the smartphone app could show that “Bell&#39;s Founder&#39;s Ales” is at “Scotty&#39;s Bar and Restaurant,” which is X miles away from your location. The location could be plotted on a map. Plus the app could get the data that the keg is currently 50% full and do the math to determine (and display) that there are “currently 110 pints left” of this beer. 
     Simple social media integration services can be created for the retailer using techniques understood by those skilled in the art. Using the data already in the SaaS Database, social media alerts can be sent automatically based on rules set by the retailer. That retailer can be prompted during their initial SaaS web setup to have the option of sending a TWITTER tweet or FACEBOOK status update when a new keg of beer is tapped. They would enter in their social media account name and password, then choose a template social message like: 
     “Just wanted to let you know that we just tapped a new keg of &lt;BEER BRAND AND TYPE INSERTED HERE&gt; at &lt;NAME OF BAR-RESTAURANT LOCATION&gt;. Come on down and get a pint now! #greatbeer” 
     For example, say that retailer was “Scotty&#39;s Bar and Restaurant,” and they have a new, full and untapped, keg of “Bell&#39;s Founder&#39;s Ale” in their cooler. This keg has a keg sensor/transmitter that is reporting a weight value of 20, which translates into a 100% full keg. Once that keg is tapped, the beer is flowing and being sold, and is now reporting a value of 19 the Twitter Tweet or Facebook Status Update is sent out: 
     “Just wanted to let you know that we just tapped a new keg of Bell&#39;s Founder&#39;s Ale at Scotty&#39;s Bar and Restaurant North Side. Come on down and get a pint now! #greatbeer” 
     Other embodiments include integration into POS terminals (Point of Sale, electronic “Cash Registers”). These POS terminals have their own APIs (Application Programming Interface) that would allow the SaaS Software to query into the POS database to extract data. This extracted data would then be added to the SaaS Database to be used for several purposes. For a given retailer, keg sensor/transmitters may be on some but not all kegs in that retailer&#39;s cooler. By pulling out sales data for a tap that is serving a given brand and type of beer, but is coming from a keg that does not have a keg sensor/transmitter, the SaaS application can estimate the keg depletion and the same alert rules and actions of re-order can be applied. In addition, a retailer can look at the depletion rate of a keg with a keg sensor/transmitter and compare it with the POS data on that same keg as it is reported by the POS system. By comparing the real volume data obtained from the present system with the reported sales data, a retailer can assess waste and shrinkage on that tap from “free pours” (keg beer poured to patrons to gain tips, or pours to employee friends). 
     The keg sensor/transmitter can be used in some embodiments to pinpoint the location of individual kegs in a warehouse. 
     Current technology for radio transmission and reception allows for location of a transmitted signal in a wide area. Using triangulation plotting a transmitter like the one on a keg sensor/transmitter would be a broad area. In the embodiments described in previous sections of this document, the Sensor is put on a keg as it leaves the warehouse to be delivered to the retailer. In other embodiments, however, the sensor could be put on the keg as it is delivered from the brewery to the beer distributor warehouse. As shown in  FIG. 12 , additional location technologies, whether now existing (such as RFID) or hereafter developed, in such embodiments allow for pinpoint location of a keg in a warehouse. The location can be shown on a computer-drawn map of the warehouse showing the X-axis and Y-axis location of an individual keg, but also the Z-axis. The Z-axis is the height, as when the keg is stacked up on a shelf. So in the future if a beer distributor is missing a keg, or group of kegs, by using the present system they could locate the keg. There could be a plot on a screen that shows the missing keg is in row 2, aisle 3, shelf 3. 
     In some embodiments the keg sensor/transmitter can be a direct CDMA or other cellular data connection. Using the longitude and latitude data from each wireless-data-equipped keg sensor/transmitter, each keg can be located when on the road for delivery and located after delivery to determine whether the individual keg has been delivered to the correct location or delivered in error to the wrong location. 
     Other uses would include bulk containers of soda, such as COCA-COLA or PEPSI, and containers of home-delivered water, such as ICE MOUNTAIN and CULLIGAN. 
     There are several brands of home keg coolers marketed to consumers. The keg sensor/transmitter could be integrated into the design of these home coolers to measure the remaining beer and alert the consumer.
