The MainFLO Doppler flowmeter measures and records flows for open channels and part-filled pipes.

It is composed of:

  • A portable or stationary central unit,
  • An immersed or emerged height
  • The Doppler Velocity Probe DVP

Thanks to the DVP technology, it is able to measure flows in dry and rainy weather.


Portable self-powered unit:

  • Comprising electronics and display unit, housed in a strong, waterproof (IP68) suitcase with military-type connectors.
  • Particularly useful for waste water and rain water diagnostics and measuring other clear water. It can also be connected to an automatic sampler, for pollution analyses.
  • It can be installed on a permanent basis on sites without electricity. Its 12 V power supply (option of internal or external) gives the required endurance (contact us).


Stationary unit:

  • The device is delivered in an IP67 box and has the same electronics as the portable version, and is equipped with 4 user configurable 4-20 mA outputs.
  • It is particularly useful for the regulatory monitoring of water treatment networks (storm overflows, characteristic points…).
  • The MainFLO can operate on either 12 V or 24 V, which allows all types of power option (mains power, battery, solar panels, etc.).
