Pressure Reducing Hydrometer IR-920-M0-54-KX

The BERMAD Model IR-920-M0-54-KX 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 reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop. It is a Normally Closed Hydrometer, which opens in response to a remote pressure rise command.
