IR-920-MO-54-bK

Pressure Reducing Hydrometer

The BERMAD Model IR-920-M0-54-bK 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 Hydrometer accurately reduces higher upstream pressure to very low and stable preset downstream pressure. It is a Normally Closed Hydrometer that opens in response to a remote pressure rise command and shuts in the absence of that command.
