IR-972-M0-50-RV - Bermad

Flow Control and Pressure Reducing Hydrometer IR-972-M0-50-RV

The BERMAD Model IR-972-M0-50-RV 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 irrigation together with the irrigation controller. The BERMAD Hydrometer limits the flow and downstream pressure to a constant preset maximum. It either opens or shuts in response to remote pressure commands.
