Abstract
An apparatus and method for the cordless remote control of a filling function of a mobile vehicle that includes a signal transmitter (12) and a liquid level sensor (14) that is mounted on a tank (18) of a mobile vehicle (16). The liquid level sensor (14) transmits a full signal to a remote signal receiver (22) by way of the signal transmitter (12). The full signal closes a control valve (26) interupting the flow of the fluid to the tank (18) by way of a conduit 28. An adjustable timer (44) provides a system safety back-up signal that closes the valve (26) if the full signal is not received within a preset time period. This apparatus and method can be operated in a semi-automatic mode or an automatic mode by the addition of an adjustable delay clock/timer (42). Audible and/or visual indicators are provided for monitoring the status of the filling operation.
