4.3 Function
The product is electrically connected to the filling device of the tank vehicle.
This connection heats up PTC thermistor which releases the filling process.
If the level in the tank is high enough for the medium to reach the PTC ther-
mistor, it changes its resistance. The control unit of the tank vehicle closes
the shut-off valve and filling is stopped.
