Do differential pressure or flow meters measure velocity?
Thread Content
Dear experts, do differential pressure or flow meters be used to measure flow velocity? What principle is it using? What is the formula? I seem to have learned it in college, but I’ve forgotten it?
Got it, it’s Bernoulli’s equation: P + 1/2pv² + pgh = constant
Anemometers, also known as pitot tubes, and the Pitot-Static tubes that have been developed based on their principle, all make use of Bernoulli’s equation.
