ABSTRACT:
The conductivity of the flushing water in the two siphons is measured by means of two electrodes (16, 17, 18, 19) in each siphon. Whenever the conductivity exceeds a predetermined limit, the flushing operation is triggered after a delay time predetermined by an electronic control device. If the two urinals are used at the same time, one of them is blocked by means of an electronic circuit (30) while the other is flushing so that both urinals are prevented from flushing simultaneously. This has the advantage that the same diameter of pipe can be used for the main water supply line as in a single-urinal installation. Whenever the conductivity of the flushing water in the siphon drops below a certain minimum or exceeds a certain maximum after a predetermined number of flushes or a predetermined length of time, flushing is interrupted by means of electronic circuits (28, 29). Such trouble is displayed on the front panel of the control unit by LED's.
