Differential Pressure Flow Meters For Reliable Flow Data

Differential pressure flow meters are instruments that measure the flow rate of liquids, gases, or steam by detecting the pressure drop across a constriction in the flow path. The constriction could be an orifice plate, venturi tube, flow nozzle, or pitot tube, which creates a difference in pressure proportional to the square of the flow rate. This pressure differential is then converted into flow readings using mechanical indicators or electronic transmitters. DP flow meters are widely used due to their reliability, versatility, and suitability for a broad range of fluids, including clean and slightly viscous liquids, steam, and gases. They are often integrated into industrial process control systems for monitoring, regulation, and safety applications.
