A portable clamp-on ultrasonic flow meter is a non-invasive device used to measure the flow rate of liquids by employing ultrasonic technology. It clamps onto the outside of a pipe without the need for direct contact with the flowing fluid.
This type of flow meter uses ultrasound to measure flow. It sends ultrasonic pulses through the pipe wall into the liquid, and the reflection of these pulses is used to calculate the flow rate based on the time taken for the signals to return.
a. Non-invasive installation, which means no disruption to the pipeline.

b. Versatility, as they can be used on various pipe materials and sizes.

c. Suitable for measuring clean or dirty liquids.

d. Ideal for temporary or spot flow measurements
Portable clamp-on ultrasonic flow meters can measure a wide range of liquids, including water, wastewater, chemicals, oils, and many other clean or dirty liquids.
