Flow rate in pipelines – Clamp ON

What is and what is used for

he ETG Clamp On is a device that measures the water flow rate in a pipeline based on the principle of the difference of transit time of an ultrasonic pulse. An acoustic (ultrasonic) signal is transmitted in both directions by one sensor to the other. The propagation velocity of the acoustic waves in the flow direction is greater than that in the opposite direction and, as a result, a difference in transit time proportionate to the flow velocity is calculated.


The Clamp On ultrasound flow rate measurement system consists of a transmitter and its measurement sensors. All components are available in different versions designed and developed to meet the various application needs. The transmitter powers the measurement sensors. The electronics and software contained in the transmitter prepare, process and analyse the signals transmitted by the sensors and convert the measurement signal into the desired output variables.
