Doppler flowmeters

Flow meter for liquid Energoflow DF

Energoflow DOPPLER FLOW METER with clamp-on sensors


Ultrasonic Flow Meters Energoflow DF with clamp-on sensors are designed for measuring flow velocity, volumetric flow rate and volume of fluids and gases, transported through pipelines in the forward or reverse direction using the Doppler effect. They can be used for measuring acoustically opaque fluids – slurries, liquids with suspended particles and other contamination..

These Doppler Flow Meter can be used for various pipe materials: steel, cast iron, asbestos cement and plastic pipelines, etc.

The major advantages of the Ultrasonic Flow Meters Energoflow AG DF are:
  • Easy installation and simplicity of use;
  • Applicable for measurements in pipelines even if the pipe walls are greatly corroded or have a thick layer of sediment;
  • Easy integration into all kinds of process management systems;
  • Reliable and accurate measurement
