Abstract
A liquid retention system is disclosed which includes a tank for receiving and retaining a liquid, and including a filling port. A dispenser supplies liquid to the tank through a nozzle which engages the filling port. A pneumatic detection system is provided for fluidly measuring the liquid level state within the tank; i.e., determining whether or not the tank is full. An optical detection system is also provided, which cooperates with the pneumatic detection system, for optically measuring the liquid level state within the tank.
