Pressure Reducing Hydrometer

The BERMAD Model IR-920-M0-55-R integrates a vertical turbine Woltman-type water meter and a diaphragm actuated hydraulic control valve. As the system's Flow Meter and Main Valve, it controls system irrigation together with the irrigation controller. The BERMAD Hydrometer reduces downstream pressure to a constant preset maximum. It either opens or shuts in response to an electric signal.
