Flow Clamp-On Type Ultrasonic FlowmeterUCL / SFC



*Specifications are subject to change without prior notice.

UCL/SFC is a clamp-on ultrasonic flowmeter for PFA piping.
There is no need for additional piping work because the flow rate can be measured just by sandwiching the existing tube. The piping is virtually kept clean.
This meter is most suitable for processes requiring cleanliness of semiconductor manufacturing equipment, etc.

 · Detector: UCL (Large diameter, Small diameter)
 · Converter: SFC010C (1CH), SFC011C (6CH)


  • · Clamp-On

    The flow rate can be measured simply by sandwiching the existing tube with the meter.
    It is essentially clean because it does not come in contact with the inside of the pipe.

  • · High-speed processing

  • · Zero adjustment

    By performing zero adjustment before measurement, you can start the measurement for the fluid under the optimum conditions.

  • · Abundant functions

    · The seven-segment LED display (red, 4 digits) indicates the instantaneous flow rate and status.
    · Various analog outputs of instantaneous flow rate (select according to output types).
    · Frequency output (1 kHz F.S.), error output, instantaneous flow rate upper/lower limit alarm,
      integrated flow rate output, and integrated flow rate upper limit alarm (open collector).
    · RS-485 communication enables parameter setting and flow rate data acquisition.

  • · Applicable standard

    · Applicable EMC standards: EN61326-1, EN61326-2-3
    · RoHS2 compliant
