*Specifications are subject to change without prior notice.

The UCUF-04MT ultrasonic flow meter for high-temperature applications is an enhanced version of the UCUF series which are best suited for measuring low flows such as ultra-pure water and chemical liquids. All the wetted parts are made of special grade PFA material and have no moving parts or mechanical
seals such as O-rings. This clean structure without dead pockets makes the flow meter the perfect choice for the semiconductor industry, which requires extreme cleanness.
The SFC-010T is a thin converter, which can be installed on the DIN rail.
Using state-of-the-art technologies such as digital signal processing (DSP), this converter ensures stable Flow measurement by minimizing the adverse effects of bubbles in the fluid, which are significant problems in semiconductor manufacturing and chemical liquids handling processes.
Furthermore, measurement at low flow rate has been stabilized by increasing the time resolution and accelerating signal processing compared with existing products.

Features

  • · Saves energy and space

    The SFC-010T is more compact than conventional models.

  • · High-speed calculation

    The SFC-010T achieves 10-ms high-speed sampling.

  • · Significantly improved resistance to bubbles

    Bubbles contained in liquids interfere with the propagation of ultrasonic waves and can prevent flow measurement.
    Based on proven field experience and state-of-the-art DSP signal processing technology, TOKYO KEISO CO., LTD. Has succeeded in achieving stable measurement by detecting the effect of bubbles from waveforms and then eliminating the abnormal output from the measurement values.
