The BERMAD IR-900 Series Hydrometer is a unique product integrating both a vertical turbine Woltman-type water meter and a diaphragm actuated control valve. The flow metering unit is vertical to the pipeline and includes an impeller with integrated inlet and outlet flow straighteners, eliminating the need for straightening distances, enabling vertical installation, and ensuring accuracy during control tasks. The raised seal seat results in remarkable cavitation resistance due to the valve body’s distance from the flow. IR-900 provides the full spectrum of metering functions from simple visual readout, through non-computerized dose control, to pulse output for computerized data capture and control while simultaneously allowing for numerous control valve features such as pressure, level and flow control.
