Ultrasonic Flowmeter for small liquid flow

UCM-04A/ 06A

Outline

UCM-04AUCUF-04MUCM-04A-SP

For pure water, ultra-pure water and chemicals, the small sized ultarasonic flowmeter UCM-04A/06A provides you with precise and stable flow measurement.
By integrating a detector and a converter this compact instrument saves your space. The digital numerals and bar-graph indicator on the front face make field monitoring easier. All wet parts consist of molded PFA specified for semiconductor industries. The simple and clean ideal construction has no moving part and no sealing pocket where liquids would stagnate.
The flowmeter has the inlet and outlet tubes of standard dimensions suitable for various PFA fittings. In the services where only flow monitor has been simply used so far, the UCM-04A/06A can be applied without difficulties. You can set up a flow control loop by connecting a controller and a control valve to the instrument.
The separate type ultrasonic flowmeter is available also, which is used as a conbination of detector UCUF-04M and separate type converter UCM-04A-SP. This usage is best suited in such cases that detector UCUF types have been used so far or precise liquid temperature control is requied.

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
