Flow calculation using differential pressure

WebDifferential pressure transducers have been widely used to measure flow rate of in-compressible liquids such as water. The most common method is to measure the pressure drop across an orifice plate in the pipe and calculate the flow rate. An orifice plate is simply a plate installed in the pipe, usually between flanges, that has a hole of a ...
