Claim 5:
6. A monitoring and remote control system for supplying a Liquid Petroleum Gas (LPG) from a tank-vehicle to a stationary tank, to be supplied or refueled with LPG, the system comprising:
a tank vehicle that comprises: tank LPG level sensor and a tank output line;
the tank output line having: a solenoid valve configured to allow or deny the flow of the fluid through said output line, a flowmeter configured to measure the amount of the fluid flowing through said output line, a connector on a distal end of said output line, the connector configured to couple with an entry port of the stationary tank;
at least one mobile computing device configured to wirelessly communicate, having a memory and a processor;
a central computing station having at least one computer device configured to wirelessly communicate with the at least one mobile computing device;
a server with a memory and processor, the server supports a digital connection to the computer device of the central computing station;
a first manager having hardware, software, power supply, an antennae module and switching means and coupled with the solenoid valve and configured to wirelessly communicate with the at least one mobile computing device;
a second manager having hardware, software, an antennae module, and a power supply, and coupled with the flowmeter and configured to wirelessly communicate with the at least one mobile computing device;
a third manager having hardware, software, an antennae module, and a power supply and coupled to the fluid level sensor and configured to wirelessly communicate with the at least one mobile computing device;
wherein at least one mobile computing device sends an authorization request to the central computing station to allow LPG to flow from the tank-vehicle to the stationary tank; and in response the central computing station grants or denies authorization;
wherein the central computing station computer device sends the request response to the at least one mobile computing device;
wherein if the request is authorized, the at least one mobile computing device activates the solenoid valve by means of an encrypted signal which is sent to the first manager which decrypts the signal and activates the switching means that energize the solenoid valve allowing the flow of LPG from the vehicle tank to the stationary tank;
wherein the second manager sends LPG flow readings provided by the flowmeter to the at least one mobile computing device;
wherein the third manager sends vehicle tank fluid level readings provided by the level sensor to the at least one mobile computing device;
wherein the flowmeter readings provided by the second manager and tank-vehicle LPG level sensors provided by the third manager are received in real time and are compared to each other in real by the at least one mobile computing device time as a security system configured to ensure the fluid withdrawn from the vehicle tank is placed in the stationary tank without diversion or leakage while the fluid is supplied from the vehicle tank to the stationary tank.
