Differential pressure flow measurement is one of the most widely used measurement principles in the industry. The main field of application is the measurement of water in heating and cooling circuits and the measurement of steam and condensates at very high temperatures in secondary circuits.
The aim is to create a localized restriction of the section (or constriction), within the pipeline, which will generate a differential static pressure. Its measurement will allow the flow deduction.
