Pressure Sustaining Hydrometer

The BERMAD Model IR-930-M0-50-R 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 sustains minimum preset upstream (back) pressure. It either opens or shuts in response to remote pressure commands.
