The EUSONIC flowmeters work on the Transit time ultrasonic principals. This put simply, involves sending and receiving ultrasonic pulses from a pair of sensors and examining the time difference in the signal. This is a more direct method of determining flow than some other systems and thus provides a more reliable measurement.

Ultrasonic transducers are mounted on the external surface of the pipe and are used to generate ultrasonic pulses which are passed through the pipe wall. The flowing liquid within causes time differences, frequency variations and phase shifts in the ultrasonic signals which are then evaluated by the flowmeter to produce an accurate flow measurement.

The key principle is that sound waves travelling with the flow will move faster than those travelling against it. The difference in the transit time of these signals is directly proportional to the flow velocity of the liquid and thus the volumetric flow rate. Whilst elements such as flow profle, liquid type and pipe material could have an effect on the measurement, the flowmeter electronics compensate for and adapt to changes in the medium in order to provide a reliable measurement.

The fast digital processors and sophisticated analysis used in the new EUSONIC flowmeter guarantee reliable, respectable results, even when used of a clamp-on flowmeter would not have been possible.

All measurements are independent of pressure and do not disturb the integrity of the pipeline in any way. This allows the flowmeter to be fitted to pipes where size, pressure, temperature, liquid type or pipe access would have made the installation of an invasive measurement device impossible.

No shut-down, no lost production

No pressure drop

No costly and risky mechanical installation

Low maintenance, no danger of blockage or damage

Quick and simple installation

Cost effective solution, particularity on large pipes.
