All of our Woltman meters can be retrofitted with active or passive pulsers without damaging the calibration seal. Up to 2 Reed sensors and one active pulser can be simultaneously attached.
Features
As a passive pulser, the Reed sensor is designed as a potential-free normally open contact. It is closed with a frequency proportional to the flow rate by a serially integrated magnet within the counter, and opens itself automatically again. Typical pulse values are 100, 1000, and 10,000 L/lmp., depending on meter size and mounting position. The Reed sensor does not require its own power supply and is therefore the ideal partner for all electronic devices whose energy supply comes from a battery.
