Tokyo Keiso UCM-04A/ 06A Ultrasonic Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: UCM-04A/06A
The SFC-900 is used as a converter for UCUF series ultrasonic flowmeters. Using patented Subtracting Correlation Method by TOKYO KEISO CO., Ltd., the converter offers stable flow measurement by eliminating drastically the adverse effects caused by the bubbles contained in semiconductor and chemical liquid handling processes. The value-added simple circuit configuration of Subtracting Correlation Method has realized high-performance flowmeter at inexpensive price.
Features
- Integration of a detector and a converter makes the piping and wiring simple
- One consolidated body saves installation space
- 3 digit indication with 7-segment LEDs and bar graph indication with LEDs on the front face make your reading easy even at dark place
- The dedicated configuration software sets the alarm and other parameters
- The meter containing clean detector consisting of wet parts made of all PFA have no moving parts, no sealing pocket where liquids would stagnate
- Zero adjustment and auto trigger functions with a hall element
- Parameter setting and flow monitoring from your PC via RS-485 communication
Applications
- Pure water and ultra-pure water services in semiconductor manufacturing plants
- CMP (Chemical Mechanical Polishing) slurries
- Chemical treatment facilities
- Corrosive chemicals
- Other liquid flow measurement of very low and low rate
