Ultrasonic Transit Time Flowmeter

The ChronoFLO2 is a new generation high-end ultrasonic flowmeter which, thanks to the quality of its sensors and powerful signal processing algorithms, pushes the limits of traditional ultrasonic flowmeters.


  • Verification of existing meters and flow meters
  • Sectorization and leak detection
  • Volume quantification
  • Diagnosis of networks (drinking water, wastewater, industrial fluids, etc.)
  • Instrument calibration/calibration of pumps
  • Backup equipment in case of flowmeter breakage

Main benefits

  • Non-intrusive installation, simple and fast, without shutting down the process or requiring civil engineering works
  • Large range of pipe diameters (12mm/0.5" to 3.2m/125")
  • Compatible with many fluids and materials
  • No contact with the fluid, no risk of contamination
  • High precision, even at low velocities
  • Reduced sensitivity to sources of flow disturbance
  • Possibility of double set of sensors
  • Robust and waterproof (IP67/IP68)
  • Can be used on sites with or without power, for temporary or permanent measurements
  • Possible connection to control and telemetry systems
  • Repair, maintenance and calibration services offered in Quebec


  • 4 sensor models according to diameter range and temperature (1 MHz/2 MHz/0.5 MHz/0.5 MHz HP)
  • Possibility to connect 2 sets of sensors (simultaneous measurements on two pipes, or on the same pipe for improved accuracy)
  • Can be used on all pipes made of homogeneous and sound-conducting material
  • Bidirectional measurement, up to 25 m/sec.
  • Accuracy: up to +/-0.5% depending on application and number of sensors
  • Measurement of up to 20 g/l of TSS possible
  • 2 4-20 mA inputs (active or passive) for connection of flowmeter to be verified, pressure sensors, temperature...
  • 2 pulse outputs for alarms, equipment control or connection to a control system.
  • 5.7'' color graphic LCD screen and ergonomic keyboard
  • Internal or external power supply (battery or 120V charger socket)
  • Battery autonomy of 140 h (continuous measurement) to 1 month (1 measurement / 5 min)
  • Logging capacity of 1 million data readings, transferable via USB key
