Unimet RS-M100

WATER METERING

PN: PG100#M100

The UniMet RS-M100 is a passive pulse transmitter developed for mechanical water meters that use built-in magnetic pointers. The device uses a reed contact switch to detect each pulse, providing a completely passive signal without power supply, ideal for low-power systems.

When the magnetic pointer is detected, the reed switch connects the “Pulse” output to “GND”. Integrated resistor of 100 Ω, enables safe integration with different types of counters and data loggers.

The device is compatible with various water meters with magnetic pointers, such as water meters manufactured by Honeywell, Elster, Ikom, Grabar, especially the M100 series.
