FIELD: measuring equipment.SUBSTANCE: invention belongs to measuring equipment and can find application in systems of water consumption counting. The device contains a calculating block of a water counter with visual indication of flow readings. Thus the block of the water counter is executed from a non-magnetic material. In the casing of the water counter a mechanical digital counting device is placed. The electric circuit of the water counter includes serially connected a counting normally open magnetically operated sealed switch, installed in the casing with possibility of periodic magnetic interaction with a permanent magnet, and a resistor of short circuit load, two outputs of the water counter electric circuit, one of which is connected to a magnetically operated sealed switch, and the second one - to the resistor, the load resistor and the break resistor connected to outputs of the electric circuit of the water counter in parallel to the magnetically operated sealed switch and the resistor.EFFECT: expansion of functionality.7 cl, 5 dwg |
