Non Invasive Flow Meters

We offer a range of fixed and portable non-invasive ultrasonic flow meters with Transit Time (for clean liquids) or Doppler technologies (for dirty / aerated liquids) as well as Hybrid ultrasonic meters which combine both principals. Available to buy or to hire.

Clamp on ultrasonic flow meters are ideal for applications when system shut down is not feasible, they are non-invasive and simply clamp on to the outside of the pipe and do not make contact with the internal fluid. They measure the time it takes for an ultrasonic signal transmitted from one sensor, to cross a pipe and be received by a second sensor.
Clamp on ultrasonic flow meters have become more popular throughout the water, food, chemical, process and building services industries due to their ability to measure in-situ flow rates from outside the pipework with optimum accuracy.
Our Clamp-on non-invasive ultrasonic flow meters are available for a wide variety of pipe materials in sizes from 13mm up to 5000mm. We also have models that can measure both flow and heat energy.
