What is an Averaging Pitot Tube? – Principle, Advantages
Averaging Pitot tube is a multiport flow meter based on the principle of measurement of differential pressure created when an obstruction is placed in flow.
Wedge Flow Meter Principle
The wedge Flow Meter measures the volumetric flow rate by calculating the differential pressure created across the wedge restriction in the pipeline.
