GST/SFC011GS-series Clamp-on ultrasonic flowmeter

Energy saving and space saving
High-speed operation
Abundant functions

GST/SFC011GS is a clamp-on ultrasonic flowmeter for small diameter piping.

There is no need for additional piping work because flow rate can be measured just by sandwiching the existing tube. The piping is virtually kept clean.

Most suitable for processes requiring cleanliness, such as Semiconductor manufacturing equipment, etc.

  • Detector: GST
  • Converter: SFC011GS

Please see the datasheet for all the options that can be chosen for the detector and converter models that are available.

Features

  • Clamp-On
    Flow rate can be measured just by sandwiching the existing tube.
    Essentially clean because it does not contact the piping.
  • Energy saving and space saving
    Simultaneous measurement of up to 6 lines with one SFC011GS.
    Multiple units can be connected (No need for crossover wiring).
  • High-speed operation
    30 ms arithmetic 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).
    • Parameter settings and flow rate data acquisition are available via RS-485 communication.
    • RS-485 communication converter (sold separately) is required.
       
  • Applicable standard
    • EMC conformity standards: CISPR11:2009+A1:2010 Group1 ClassA, EN61326-2-3:2013
    • RoHS2 compliant
