V a Valves flowmetering Woltman Water Meter

The sensor is designed as a potential-free normally open contact. It is closed with frequency proportional to the flow rate by serially integrated magnet within the counter and opens itself automatically again. Typical pulse values are 10, 100 and 1000 LImp., depending on the meter size and mounting position. The pulse output sensor does not require its own power supply and is therefore the ideal partner for all electronics devices whose energy supply comes from a battery.
