Differential pressure (DP) flow meters are widely used to measure the flow rate of fluids, including gases, liquids, and steam, in pipelines. The basic operating principle behind these devices is that as a fluid flows through a constriction, the pressure drops in proportion to the square of the flow velocity. This pressure difference is then […]
