IR-920-MO-bRZ

Pressure Reducing Hydrometer

The BERMAD Pressure Reducing Hydrometer integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Serving as Flow Meter and Main Valve, it controls irrigation together with the irrigation controller. The BERMAD IR-920-M0-bRZ accurately reduces higher upstream pressure to very low and stable preset downstream pressure.
