Flow Control Hydrometer IR-970-M0-54-KV

The BERMAD Model IR-970-M0-54-KV 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 limits the flow to a constant preset maximum. It is a Normally Closed Hydrometer, which opens in response to a remote pressure rise command and shuts in the absence of that command.
