Diaphragm valve 900/M0-R02

hydraulically-operatedmeteringfor water

Product Overview
The BERMAD Hydrometer with hydraulic relay combines a Woltman-type turbine water meter and a hydraulically operated diaphragm control valve. It functions as a mainline flow meter and a normally closed control valve, opening on a remote pressure-rise command and closing when the command is absent. The unit includes a magnetically coupled, vacuum-sealed register for accurate volume measurement. An optional reed-switch pulse output is available for integration with remote monitoring systems.

Key Model Details

• Model designation: IR-900-M0-54-3W-KX
• Series: 900 Series
