In industrial applications, the most common use of pressure sensors to calculate another parameter is flow. Q = c D π/4 D 2 2 1/2Ĭ D is the discharge coefficient, and is the area ratio = A 2/A 1ĭ 2 is the orifice, venturi or nozzle inside diameter (in m)ĭ 1 is the upstream and downstream pipe diameter (in m) In these cases, the flow is related to ΔP (P1-P2) by the equation: In fact, many applications use pressure sensor measurements to calculate other key parameters such as flow, altitude, water column height, fluid depth, weight and more.įor fluid flow measurements, orifice plates, venturi tubes and nozzles simplify the use of differential pressure (ΔP) sensors to determine the flow rate. With the high volume, low cost and reliability of microelectromechanical system (MEMS) pressure sensors, these products are a frequent choice for measuring both liquid and gas flow. A variety of techniques are used to measure flow, including: the Coriolis Effect, mass air flow, vortex, magnetic, thermal, ultrasonic, turbine and positive displacement meters as well as pressure sensors.
