*Specifications are subject to change without prior notice.

SONICMAXUL6300 V2 is an ultrasonic flowmeter using the time-of-flight system, combining a highly efficient converter (UFC300 V2) with a clamp-on sensor (UFS6000 V2). Three kinds of sensor without direct contact with the fluid enable the measurement of a wide range of flow, for pipe sizes from 15 mm to 4000 mm.
A new type of converter with a stainless steel sensor rail and an integrated sensor cable allows simpler installation on pipes, easier maintenance, and higher weather resistance than existing models. Moreover, the highly efficient converter compatible with multiple sensors is easier to use, enabling stable high-precision measurement of low-velocity flow with digital signal processing system and powerful status diagnostic functions.


  • ・ The non-contact measurement system where the sensor is in-stalled on the exterior surface of the pipe completely eliminates the generation of particles and mixing of metal ions, making the method ideal for flow measurement of pure water and chemical liquids.
  • ・ The highly efficient converter compatible with multiple sensors can measure two lines simultaneously. Precise flow measurement is ensured by calibrating uneven flow by measuring two lines in one stream.
  • ・ The digital signal processing system enables stable and precise measurement of low-velocity flow. Measurement accuracy is ±1% of the indicated value (connection: 50 mm or more, velocity: 0.5 m/s or more).
  • ・The sensor part can be used for pipe sizes ranging from 15 mm to 4000 mm by three kinds of sensor (small/medium/large).
  • ・ Mounting and maintenance are made easy by integrating the sensor rail, sensor, and cable. Also, weather resistance is improved by using stainless steel for the sensor rail as standard.
  • ・ A connection box allows integration of the cable extension and cable connection.
  • ・ A blue dot matrix LCD (with backlight) is used for the display (128 × 64 dots, 59 × 31 mm). Bar graph indication, multi-line indication, real-time trend indication, etc. are provided.
  • ・ A quick setup function makes it easy to change the flow range, pulse rate, etc.
  • ・ A new button switch for changing the settings improves operability along with the infrared sensor of the existing model.
