*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.

Features

  • · New signal processing has improved anti- bubbles capability of converter.
    Normally, ultrasonic flowmeter has difficulty in measuring fluid containing bubbles, because the bubbles interfere with ultrasonic signal passage.
    In virtue of DSP and accumulated field experience, anti-bubbles capability has been remarkably improved.
  • · Compact and light weight
    The detector and the converter are of separate type.
    Compact and easy wiring because of the plug-in construction of the converter.
  • · Coaxial connector
    General purpose BNC coaxial connector common to existing products
  • · Cleared EMC test conforming to EN61326-1: 2006
  • · Lead free compatible
  • · Optimal measurement because of zero adjustment before suring
  • · Measurement of high kinetic viscosity liquids as high as 40mm²/s Ideal detector with clean construction
  • · Corrosion resistant and easy installation
  • · Accuracy: within ±1% of the reading at flow velocity 1m/s or more
  • · Versatile functions including followings
    Alarm outputs of instantaneous flow rate or fault status output
    Various analog outputs of instantaneous flow rate are selectable
