What is Averaging Pitot Tube?

An averaging Pitot tube is a type of flow measurement device used to measure the average flow of a fluid, gases and steam in a duct, stacks or pipe. It is commonly employed in air, fuel, steam and gas flow applications. The averaging pitot tube consists of multiple sensing points across its cross-section, allowing it to provide an average flow measurement rather than a point flow measurement. It offers simple, low cost installation into pipes and ducts, and high energy savings due to its low unrecovered pressure loss.There are no moving parts or sharp edges to wear, so longterm accuracy can be maintained.
