World's first clamp-on saturated steam ultrasonic flowmeter


Flowmeter for steam

Clamp-on saturated steam ultrasonic flowmeter capable of measuring steam flow without the need to cut piping.

It was previously difficult to measure the steam flow used in factories in various industrial sectors, but this flowmeter can now be installed even when the equipment is in operation.


Measure the steam flow with precision thanks to a new noise reduction technology, whatever the pressure (from 0.1 MPa (G)) and temperature (up to 180 ° C).





Applications :

  • District heating
  • Metal industry
  • Pulp and paper industry
  • Heat exchangers
  • Food and pharmaceutical  (autoclaving, cleaning and sterilization process)
  • Boilers ancillaries (combustion air preheaters)


Advantages :

  • Easy, quick, economical and secure installation
  • Reliability and precision measurements
  • Maximum flexibility and wide range applications
  • Early detection of steam leaks
  • Process monitoring and corrective actions
  • Low maintenance and use
  • Designed to last in harsh industrial environments

Characteristics :

  • High accuracy

       Steam flow rate can be measured in the 0 to 50 m/s range, and high-precision measurement at ±3.0% of rate (10 to 30 m/s) is possible.

  • Measurement possible from low pressure (low temperature)

       Steam flow rate can be measured from a low pressure of 0.1 MPa (G) (temperature: 120°C).

  • Zero pressure loss

       No pressure loss,due to mounting externally on pipes.

  • High-speed calculation

       The flowmeter is equipped with a high-performance CPU, offering high-speed response of 0.2 seconds.

  • Mass flow rate conversion

       Mass flow output is possible by conversion with volume flow and density input. Density can be adjusted by pressure and temperature input.

  • Various communication functions

       The flowmeter is equipped with communication functions such as RS-485 (Modbus specification) and Ethernet (under development), which is capable of carrying out self-diagnosis as an IoT terminal device, and features a remote diagnosis function.

  • Multi-lingual

       The following languages are supported for display:

  1. Japanese (Katakana)
  2. English
  3. German
  4. French
  5. Spanish.
