Flow Control and Pressure Reducing Hydrometer IR-972-M0-54-KV

The BERMAD Model IR-972-M0-54-KV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Serving as Flow Meter and Main Valve, it controls irrigation together with the irrigation controller. The BERMAD Hydrometer limits demand and reduces downstream pressure to constant preset maximum values. It is a Normally Closed Hydrometer, which opens in response to a remote pressure rise command and shuts in the absence of that command.

  • Integrated “All-in-One” Control Valve

-Saves space, cost and maintenance

  • Line pressure driven, Normally Closed

-Closes upon control failure

-Limits fill-up rate and consumer over-demand

-Protects downstream system

-Amplifies and relays weak remote command

  • Magnetic Drive with Vacuum-Sealed Register

-Water-free gear train mechanism

-Reed-switch and Opto pulse-generating modes

-Various pulse combinations

  • Internal Inlet & Outlet Flow Straighteners

-Saves on straightening distances

-Maintains accuracy

  • Integrated Flow Metering Calibration Device
  • Paddle-Type Hydro-Mechanical Flow Pilot

-No added head loss

-Wide setting range

Typical Applications
