Portable Ultrasonic flow measurement of liquids in hazardous areas

Page last modified
May 10 2023

Portable instrument for non-invasive, quick ultrasonic flow measurement with clamp-on technology for all types of piping 


  • Precise bidirectional and highly dynamic flow measurement with the non-invasive clamp-on technology 
  • High precision at fast and slow flow rates, high temperature and zero-point stability 
  • Portable, easy-to-use flow transmitter with 2 flow channels, multiple inputs/outputs, an integrated data logger with a serial interface 
  • Extremely resistant carbon fiber housing 
  • Covered by ATEX/IECEx zone 2 certification 
  • Compact and very lightweight, allowing the measuring system to be easily carried as personal luggage, e.g. for offshore visits 
  • Watertight; resistant against oil, many liquids and dirt 
  • Li-Ion battery provides up to 25 hours of measurement operation 
  • Automatic loading of calibration data and transducer detection for a fast and easy set-up (less than 5 min), providing precise and long-term stable results 
  • User-friendly design

Designed for the following industries: 

  • Upstream (on- and offshore) 
  • Midstream and downstream (pipelines and refineries) 
  • Chemical industry 
  • Energy sector (e.g., HVAC, geothermal, power plants)
