The F401 H20 is a portable, clamp-on ultrasonic flow meter for the water and sanitation sector. This flow measurement device offers stable and precise bi-directional flow measurements with high measuring accuracy, even at low flow velocities. It is effective as a rural outdoor water flow meter (continuous measurements of up to a week are achievable), applicable for service and maintenance activities, for long or short term monitoring, data logging and existing meter verification. It is suitable for pipes of 40 mm to 3 m and it can handle solid contents of up to 6% by volume, and can handle flow velocities of 0.03 to 82 ft/s.

More Information

Typical applications include:

  • Water and wastewater applications
  • Clean measurement process for drinking water
  • Leak detection
  • Water loss balancing
  • Verification of sewage lift station performance
  • Temporary monitoring of distribution and collection
  • Verification of pump and valve performance

Benefits of the  F401 H2O:

  • Non-invasive installation
  • Water-tight, submersible transducers
  • Zero point stable and able to recognize even the smallest flow rates, thus ideal for leak detection
  • User-friendly menu navigation – the firmware is specifically adapted to the needs of the water industry


Portable Flowmeters for Liquids

FLUXUS® measures flow rates of liquids non-intrusively with ultrasound. Portable, clamp-on ultrasonic transducers are simply mounted on the outside of the pipe. The practical advantages include:
  • No wear and tear by the medium flowing inside the pipe
  • No risk of liquid leakage or fugitive gas emissions
  • No pressure loss
  • Unlimited plant availability.
