Unimet PG-H4/C4 (P)

WATER METERING

PN: PG100#H4/C4 (P)

UniMet PG-H4/C4 (P) is a high-precision pulse output developed for mechanical water meters with inductive indicators. It is designed to provide reliable flow reading via open-collector output, enabling compatibility with almost all modern remote reading systems.

Thanks to the dual output – uncompensated and compensated – the device offers full flexibility from complete flow analysis including the direction of water movement, to simple consumption summation with automatic correction of the return flow.

UniMet PG-H4/C4 (P) is intended for installation and has full compatibility with the Honeywell-Elster-Ikom H4000 and C4000 Primary meter water meters.
