WebIts flow rangeability of 3:1 (some operate at 4:1) is also similar to the capability of the orifice plate. Pitot tubes, like orifice plates and other differential pressure flow meters , function on the principles of the Bernoulli equation – which states that as the flow of a fluid increases, pressure loss occurs.
