The BERMAD Hydrometer with Solenoid Controll integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The impeller drive is magnetically coupled to a vacuum-sealed meter register in the control head. As the system’s Flow Meter and Main Valve, it controls system irrigation together with the irrigation controller. The BERMAD Model IR-910-M0-RX opens and shuts in response to an electric signal.
