Differential Pressure Flow Measuring Principle
Flow measurement based on the differential pressure principle (Orifice-Nozzle-Venturi). Some 300 years ago, Swiss mathematician and physicist Daniel Bernoulli discovered the direct relationship between the pressure and speed of a fluid flowing in a pipe. Italian physicist Giovanni Battista Venturi also performed experiments on flow and, in 1797, he built the first flowmeter for closed …
