BM/BMA Hydrometer

The Hydrometer is a combination of a water meter and a hydraulic valve in a single unit. 


  • The valve is double-chambered and is especially designed for high-pressure operation.
  • Pilot valves and solenoid valves enable remote and automatic transmission of hydraulic commands to the hydrometer.
  • The impeller is the only moving part in contact with the water.
  • The meter contains a rotating leakage indicator as well as a totalizer that displays cumulative volume.
  • The meter electronically transmits flow data to the remote control computer.
  • The hydrometer is available in globe type and angle type models in a variety of sizes.


The BM/BMA hydrometers series are designed for remote control irrigation and for industrial applications. 

The hydrometer is especially suited for automated operation. The hydrometer may be used in a variety of pressure and flow regulation applications such as: 

  • Pressure sustaining & reducing
  • Flow regulation
  • Combined pressure and flow regulation
  • Dual stage operation


  • Integrated design minimizes installation space
  • Specifically designed for use in automated remote control environments
  • Wide variety of flow and pressure regulation options
  • Double-chambered hydraulic valve designed for high-pressure operation
  • Rugged, heavy-duty construction
  • Low loss of head
  • Wide range of sizes - suitable for virtually any application
