Product Description

The clamp-on ultrasonic transducers (sensors) are mounted on the external surface of the pipe for non-invasive and non-intrusive flow measurement of liquid and liquefied gasses in fully filled pipe. Two pairs of transducers are sufficient to cover the most common pipe diameter ranges. In addition, its optional thermal energy measurement capability makes it possible to carry out a complete analysis of thermal energy usage in any facility.
This flexible and easy to use flow meter is the ideal tool for the support of service and maintenance activities. It can also be used for the control or even for the temporary replacement of permanently installed meters.


1.50-hour battery (rechargeable), 4.3'' color LCD display all integrated into a rugged, watertight enclosure.

2. Data logger function.

3. The heat measurement function by configuring with paired temperature sensors.

4. Non-invasive transducers.

5. Wide bi-directional flow range of 0.01 m/s to 12 m/s. Wide liquid temperature range: -35℃~200℃.

6. Works reliably in both clean and somewhat dirty liquids with turbidity<10000ppm.

7. Lightweight and easily transportable in box.
