The BERMAD Model IR-900-M0-54-RXZ integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. As the system's Flow Meter and Main Valve, it controls system irrigation together with the irrigation controller. It is a Normally Closed Hydrometer, which opens in response to a pressure command and shuts in the absence of that command.
