Flow Converter for UCUF ultrasonic flowmetersSFC3000



*Specifications are subject to change without prior notice.

The UCUF series ultrasonic flowmeter is designed for measuring small flow rates of ultra-pure water and chemical liquids.
All wet parts are made of special grade PFA molds and have no moving parts or sealing mechanism such as an O-ring which would accumulate liquid components.
The simple and smooth construction leaves no residues and is ideal for processes such as semiconductor manufacturing which requires ultimate cleanliness.
The SFC3000 is a converter for UCUF series ultrasonic flowmeters.
Using state-of-the-art technologies such as Digital Signal Processing, the converter has reduced significantly the adverse effects caused by the bubbles contained in semiconductor and chemical liquid handling processes.


  • · Enhanced resistance to bubbles
  • · The converter is compact and lightweight with a plug-in construction easy for wiring.
  • · Cleared EMC test: EN61326-1: 2013 EN61326-2-3: 2013. RoHS compatible
  • · Liquids with kinematic viscosity of as high as 40 mm2/s can be measured
  • · Corrosion resistant and easy to install
  • · Accuracy: Within ±1% of the reading at flow velocity of 1 m/s or more
  • · Additional functions: Error detection, Self diagnosis
  • · Simple parameter setting suitable for each measuring liquid
