Southwest Irrigation, LLC
Southwest Irrigation is the leading supplier for Heap Leach Mining Systems and Agricultural Irrigation Systems in the southwest.

Flow Control and Pressure Reducing Hydrometer

The BERMAD Model IR-972-M0-55-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 an electric signal.
