Hydrometer 900-MO-Z

The BERMAD Hydrometer with Magnetic Drive integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The impeller drive is magnetically coupled to a vacuum-sealed meter register in the control head. Serving as Flow Meter and Main Valve, the BERMAD Model IR-900-M0-Z controls irrigation together with the irrigation controller. It opens and shuts in response to remote hydraulic commands or locally by its manual selector.
