Converter integrated type ultrasonic flowmeter

UCM®-04A/06A RoHS compliance
ULTRASONIC COMPACT METEROUTLINEThe UCM-04A/06A is the converter integrated type ultrasonic flowmeter for small flow that offers precise and stable flow measurement for
ultra-pure water and chemicals. A compact body with a detector andconverter saves installation space. The 7-segment LEDs and clear bar
graph indication on the front panel allows easy reading in the field.
The wetted parts are consisting of the molded PFA specified for semiconductor industries. The simple and clean construction without anymoving parts and without sealing pockets where liquids stagnate,makes the UCM-04A/06A an ideal choice for the clean process suchas the semiconductor plant.
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.

FEATURES❏ Integration of detector and converter makes the piping and wiring
simple.
❏ One consolidated body saves installation space.
❏ 7-segment LEDs and bar graph on the front panel makes reading
easy even at dark place.
❏ The dedicated software makes parameter setting like alarms easier than ever.
❏ The meter contains ideal and clean detector.
❏ The hall element makes zero adjustment surely.
❏ The RS-485 makes parameter setting easy.
❏ RoHS compliance

APPLICATIONS❏ Pure water and ultra-pure water services in semiconductor manufacturing plants❏ Chemical feedings❏ Corrosive chemicals❏ Suitable for very low and low flow rate services such as cleaning
equipments

DNOTES ON INSTALLATION❏ Avoid the fluids containing bubbles. The bubbles cause adverse affects for precise measurement.
❏ The detector and pipe are fully occupied with liquid. You may install the meter in either piping horizontally, vertically or slantwise, but install
the bottom face of the detector tube vertically.
Arrange the piping so that liquid inside meter is easily drained.
❏ Install the flow control valve downstream of meter, if required, to avoid adverse effects caused by the bubbles generated at downstream ofcontrol valve.
❏ Install the detector and converter away from power relays and solenoid valves that maygenerate noises.
❏ Lay the signal cable away from the power cables with high voltage and current.
