| 20150027564 | Overfill Prevention System - This invention relates to an overfill prevention system for preventing the overfilling of tanks when filling up large tanks from a fuel distribution truck. The system operates by monitoring and automatically controlling the filling process by use of a power take off switch assembly that is connected electronically to a secondary overfill prevention system that is also connected to a signal probe located in the tank that is being filled. In operation, once fuel contacts the signal probe, a communicator signal is sent from the signal probe to a secondary overfill prevention system, which interrupts a looping electrical current through a fuel shut off sensor assembly to a power take off switch assembly along a connecting cable. Once the looping electrical current no longer returns to the power take off switch assembly, an indicator light turns off and a pneumatic switch is flipped, which automatically stops the flow of air from the distribution truck's air tank to the power take off that drives a pump that is controlling the flow of fuel. This stops the flow of fuel to the tank and prevents costly, damaging and dangerous overfills. | 01-29-2015 |
