*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 SFC4000 is a panel-mount type converter for UCUF series ultrasonic flowmeters.
Using state-of-the-art technologies such as Digital Signal Processing and Tokyo Keiso tuning, the converter has reduced significantly the adverse effects caused by the bubbles contained in semiconductor and chemical liquid handling processes.
The SFC4000 has display, setting,and communication functions. While checking the status on the display, operators can perform centralized control via MODBUS communication
