An input of a processor unit (3) is connected to a sensor output of the flow meter (1) and the output of the processor unit (3) is connected to the input of the electromagnetic valve (2). At the same time are the flow meter (1) and the electromagnetic valve (2) bridged by a hand operated valve (4).
