Supervision system for filling operation of tanker lorry

摘要

The tanker (10) has an electronic control (58) with controller memory. The bottom valve (14) has a sensor (56). Down-current from the bottom valve is a first sensor (52) indicating that the compartment is empty. Directly on the up-current side of the coupling (22) or inside the coupling is a second sensor (54) indicating emptiness. The sensors are connected to the electronic control of the tanker for storing the sensors signals in the order of their occurrence. The electronic control is connected with an indicator and or printer (64). The filler pipes (26) have an identification signal and the couplings have a reader. The electronic control is connected to the tanker by a connecting line. The connecting point (40) for the connecting cable (36) is connected to the electronic control for indicating the start and finish of loading.
