BM/ BMA- Hydrometer






  • The hydrometer combines 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

Available Sizes
