Automatic truck tank fill system

An automatic truck tank fill system comprising:

• a conduit adapted to be in fluid communication with a liquid supply source;
• an electrically controlled valve in fluid communication with the conduit, the valve having a first open position and a second closed position;
• a fill spout in fluid communication with the conduit, the fill spout comprising an outer chamber;
• a controller in electrical communication with the valve, wherein a first signal opens the valve from a closed position, permitting fluid flow through the conduit, and wherein a second signal causes the valve to close, preventing fluid to flow through the conduit;
• a tubing in fluid communication with the fill spout;
• a pressure transducer in fluid communication with the tubing, the controller in electrical communication with the pressure transducer,
• wherein when a pressure in the tube reaches or exceeds an activation pressure (P1), the controller sends a signal to close the valve in the conduit;
• a tubing breakaway connector placing the controller and the fill spout in releasable fluid communication;
• and
• the controller positioned intermediate the tubing breakaway connector and the valve,
• wherein in operation of filling a truck tank, the tank includes air, the air in communication with the tubing and pressure transducer, the fill spout is in fluid communication with the tank and liquid fills the tank, air pressure increasing in the tank until the pressure reaches the activation pressure (P1) and the controller sends a signal to close the valve and stop the flow to the fluid supply.
