Optoelectronic pulse emitter module with NPN open collector output. Pulse EVO is also compatible with suitable third-party meters.
Optoelectronic pulser for Maddalena SJ PLUS EVO and VTZ water meters, and Modularis water meters (other manufacturers) A state-of-the-art built-in optical sensor detects the revolution of the sweep hand indicating the litres. It also detects the direction of the water flow. In the event of reverse flow, the meter will count internally the volume flowed. A maximum of 1000 pulses is allowed for. When the forward flow is restored, no pulses are generated until the value of the volume flowed is zero.
