Flow Converter for UCUF ultrasonic flowmeterSFC2000



*Specifications are subject to change without prior notice.

The UCUF (Ultra-Clean Ultrasonic Flowmeter) series Ultrasonic Flowmeter is designed for very low flow rate applications.
The nonwetted Sensor design, constructed of specific grade PFA material, makes the UCUF Series an ideal choice for semiconductor industry, where extreme cleanness of pipe line inside is of primary importance.
The SFC017 is used as a converter for UCUF series ultrasonic flowmeters.
Using state-of-art signal processing technology, this converter offers stable flow measurement by minimizing adverse effects caused by the bubbles contained in the flow liquids.
Thus, it has achieved the reliable flow measurement of semiconductor manufacturing process and chemical liquids handling process.
Furthermore, the stability of flow measurement at low flow rate has been improved significantly by the upgrading of time resolution and high speed signal processing compared to the existing products.
