Pressure Reducing and Sustaining Hydrometer IR-923-M0-54-KX

The BERMAD Model IR-923-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 sustains minimum preset upstream (back) pressure and reduces downstream pressure to a constant preset maximum. It is a Normally Closed Hydrometer, which opens in response to a pressure rise command and shuts in the absence of that command.
