Pressure Reducing and Sustaining Hydrometer IR-923-M0-50-R

The BERMAD Model IR-923-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 the preset minimum upstream pressure; reduces downstream pressure to a constant preset maximum, and either opens or shuts in response to remote pressure commands.
