Understanding the Differential Pressure Flow Measuring Principle (Pitot tube)

By Endress+Hauser/YouTube

Differential pressure flowmeters, also known as DP flowmeters, create a cross sectional change in the flow tube, which causes the velocity of the flowing fluid to change. A change in velocity occurs whenever there is a change in flow cross-section; i.e., with a decrease in velocity, an increase in pressure occurs. In this short clip, Endress+Hauser illustrates how the Differential Pressure Flow Measuring Principle works. Watch this short clip to learn more.
