  Demonstration Facility Update for January 2005
  By:  Gregory Fischer, Facilities Director Phase 
  II construction is on schedule and over 90% completed.  Contractors are 
  finishing up items on checklists that should be completed soon.  High capacity 
  wells, boiler and headtank systems have been tested and run.  Inspections of 
  various system disciplines have been occurring weekly with contractors.  
  Facility  and fish rearing equipment has also been ordered and is 
  beginning to arrive. Fish rearing systems will be assembled on site by facility 
  personnel with a spring activation date (stay tuned for more info on these 
  systems in future updates).  Of course, there has been plenty of snow and ice to 
  remove from the facility grounds.  Any questions or comments should be directed 
  to Greg Fischer at 715-373-1047 or email [email protected].  Backup 
  Electrical Generator System We've 
  all experienced a loss of electrical power at one time or another. At best it's 
  an inconvenience. However, extended power failures can place your fish in a 
  life-threatening situation that at worst, could result in you digging a very 
  deep hole.  One solution would be to install a backup electrical generator 
  system that would put enough power in your hatchery facility to run all of the 
  lights and motors.  Whenever the power kicks off, a backup electrical 
  system would then automatically turn on. You don't have to even go outside (or 
  get out of bed) to turn it on. Generac manufactures a variety of generator systems designed to switch on 
  automatically in case of a power failure. Once it's activated, the generator 
  will deliver emergency electrical power to specific circuits in your hatchery 
  that you'll determine when you first install the system. When the transfer switch senses the loss of utility power, the generator system begins an initial 15-second countdown.What happens when you lose power?
    At the first hint of 
    a sustained power outage (not just a momentary flicker or surge), the generator 
    system starts up automatically in a two-stage process.  When the transfer switch senses the loss of utility power, the generator 
    system begins an initial 15-second countdown. Utility companies often experience 
    momentary voltage drops or power losses. The 15-second countdown marks time to 
    make sure the power loss is serious, and potentially long-term. At the end of 
    the initial 15-second countdown, the system turns the generator engine on and 
    fires up the system. At this point a second countdown begins, again lasting 15 seconds. The 
  generator warms up in this time, and the sensors continue to search for a 
  resumption of utility power. If this 15-second countdown expires before utility 
  power resumes, then the transfer switch flips to emergency mode. At this point 
  (a total of 30 seconds after the power loss) the generator feeds electricity to 
  your pre-selected emergency circuits. The system will continue to feed power to 
  those emergency circuits no matter how long the power is out, as long as your 
  fuel supply holds out. When the utility company restores power, the generator system takes itself 
  off-line in a reverse-countdown process. Fifteen seconds after utility power 
  resumes, the transfer switch flips back into standby mode. At that moment, the 
  generator disconnects and utility company electricity flows into the emergency 
  breaker box, just like it normally does. For the next 60 seconds, the system 
  makes sure the power resumption is permanent, and the generator engine cools as 
  it idles. At the end of that 60-second cool-down period (a total of 75 seconds 
  after utility power resumes), the generator engine shuts down. How do you choose a generator size?
  During a power outage, you won't need every available appliance and outlet. Pick 
  your circuits based on the critical needs of your facility. 
  Generac makes generator systems ranging from 6 to 40 kW of power output.  
  These emergency generator systems have been designed and built to supply 
  only temporary emergency power. They're not designed to supply full power to 
  your entire facility. Consult with a trained electrician as you decide which 
  circuits you'll want to power with your system. The electrician will help you 
  determine your total power requirement in an emergency situation, and help you 
  choose the generator capacity that best meets your needs. Features
  Several innovative features have been designed into the emergency generator 
  systems. The generator engine starts up automatically once a week and runs for 
  seven minutes to ensure the system's working properly. A built-in starter 
  battery receives a constant trickle charge from your electrical system to keep 
  the battery charged for an immediate response at the first sign of a power 
  failure. The system has a voltage regulator to maintain constant voltage levels 
  in your house. This will help minimize the power spikes and surges that could 
  damage sensitive electronics. Contact Information:Generac Power Systems, Inc.

  Guardian Elite  Water Quality Monitoring SystemHydrolab Quanta, Water Quality Monitoring System  Hydrolab Quanta Water Quality Monitoring instrument The Hydrolab 
    Quanta Water Quality Monitoring instrument makes use of the same or similar 
    sensors found in our high end Series 4a instruments but with fewer bells and 
    whistles. Consequently, the Quanta produces the same high quality measurements 
    using the same long lived sensors that one can find on our Series 4a equipment. 
    In addition, the Quanta has a three-year warranty that includes the sensors. 
    Below, you will find information on these sensors and other Quanta 
    characteristics.
 The Quanta system is a compact and complete system capable of 
    monitoring temperature, dissolved oxygen, conductivity, pH, ORP (redox), depth, 
    turbidity, and can log 100 frames of data. FreshFlow Circulator
  The circulator has several benefits. First, it provides 
  adequate flow across the dissolved oxygen sensor to insure the most accurate 
  readings. The circulator enables the DO sensor to comply with EPA Method 360.1. 
  Beyond that, the circulator provides assurance that a representative sample is 
  being measured and it reduces the rate of sensor fouling. Dissolved Oxygen Sensor
  Hydrolab uses a long-lived, oxygen-consumptive steady state 
  sensor. This sensor has the best accuracy over the entire range, complies with 
  EPA Method 360.1.  These reengineered sensors do not measure dissolved oxygen directly but 
  use an algorithm to estimate oxygen concentration from the energy it takes to 
  restore the charge to the sensor. The Hydrolab unit will update the display 
  every second while the pulse systems update the information at four-second 
  intervals. Pulse sensors require regular reconditioning and tend to wear out 
  within 12 months while several years should be expected from the Hydrolab 
  dissolved oxygen sensor. With the low power FreshFlow Circulator, long deployments can 
  be accomplished without compromising dissolved oxygen precision. This is very 
  important even in stream situations where the flow across the sensor typically 
  is less than 1 foot/second. Rebuildable pH Reference Electrode
  Hydrolabs reference electrode is rebuildable. The user can 
  replace the reference electrolyte and the porous Teflon junction. This provides 
  the user improved field readings and much longer life when compared to gel 
  filled combination electrodes. The sensor can be rebuilt in five minutes in the 
  field.  Because they are rebuildable, these sensors will last many 
  times the length of life of the gel filled pH sensors that other manufacturers 
  use. Gel filled sensors typically need replacement in 6-12 months while a 
  rebuildable sensor should last many years. Graphite Conductivity Sensor
  Hydrolabs graphite conductivity sensor eliminates the need 
  to polish nickel electrodes and provides for improved sample flow past the 
  sensor. No longer will you need to be concerned with bubbles or sediment in a 
  conductivity block or whether you are measuring a representative sample. The new 
  open design has better accuracy as well. 4 Beam Turbidity Sensor
  The Quanta turbidity option features Hydrolabs 4 Beam 
  sensor. It utilizes the measurement technology of the GLI Method 2 sensor (an 
  Approved EPA Method) that is used extensively in drinking water plants for high 
  accuracy measurements. At turbidity conditions under 30 NTUs, the 4 Beam sensor 
  has the best accuracy of any turbidity sensor found on a multiparameter sensor. 
  By using two LED light sources and two detectors, the sensor takes four 
  measurements to calculate the proper NTU value. The internal algorithms 
  automatically provide compensation for changes in light quality and for moderate 
  sensor fouling. Depth Sensors
    The Quanta has three depth sensor options. The 0-10m sensor 
    provides an accuracy of 0.01 foot over its entire range. Other depth options are 
    0-25 meters and 0-100 meters.  Real Time Clock/ PC Download
    The Quanta has the capability to store 
    up to 200 data sets. With the Real Time Clock/ PC Download option, this data can 
    be downloaded along with the data-time stamp.  For Quanta displays equipped with the Real Time Clock/ PC 
    Download option, no proprietary software is required to download data files. 
    Data files are downloaded in a spreadsheet format. The spreadsheet format is 
    comma delimited and files can be easily imported into any popular spreadsheet.      One Handed Operation
    The 5 keys are large enough and spaced far enough apart so 
    that the unit can be operated with a single gloved hand. Other displays have 
    many small closely spaced keys that reduce the ease of operation, especially in 
    wet and cold conditions.   Warranty
    Hydrolab offers a standard three-year warranty on all 
    components. Hydrolab can do this because the units are proven to be durable. 
    Compare this to manufacturers that will warrant their sensors for only six to 
    twelve months.  All Quanta components are designed and manufactured in the 
    United States.   **Return
