BERMAD Irrigation Hydrometer & Auto Metering Valves 1½" - 10" IR-900 Series Hydrometer 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. IR-900 Series range in diameter sizes of 1½"-10". Integrated "All-in-One" Control Valve { Saves space, cost and maintenance Hydraulically Controlled Hydrometer { Line pressure driven Magnetic Drive Register: { Analog rotating hands display • Water-free gear train mechanism • Various pulse combinations Typical Applications Internal Inlet & Outlet Flow Straighteners { Saves on straightening distances of pipe { Maintains accuracy Integrated Flow Metering Calibration Device { Precise measurement User-Friendly Design { Simple in-line inspection and service Computerized Irrigation Systems { Irrigation Control Head { In-Field Control Head Remote Flow Data Read-Out { Flow Monitoring & Leakage Control { Water Treatment Systems { Volumetric Irr

BERMAD Irrigation Hydrometer Open Hydrometer Closed Technical Data Solenoid Open Hydrometer Closed Hydrometer Open Hydrometer Closed Solenoid Closed Hydrometer Open On/Off Modes, Solenoid Controlled Line pressure is applied to the control chamber of the hydrometer, through the override Cock-Valve. This creates a hydraulic force that moves the valve to the closed position and provides drip tight sealing. Discharging pressure from the control chamber to the atmosphere causes the line pressure under the plug to open the hydrometer, measuring the flow rate. Line pressure is applied to the...
