| with the eyc-tech Pitot Tube Principle | eyc-tech PHM330 Differential Pressure Transmitter is built on the structure of thermal mass flow measurement, with eyc-tech AFMT Average Flow Measuring Tube(Pitot tube), based on the flow continuity formula (the law of conservation of mass) and the Bernoulli formula (the law of conservation of energy), the wind speed calculation formula is deduced to achieve an effective and accurate measurement. Flow rate formula V = K Flow formula Δ P = Difference between total pressure and static pressure ρ (Dynamic pressure)(Pa) = Flow density(kg/m3) = Flow...
