Differential pressure (DP) flow meters are widely used devices that measure fluid flow by calculating the pressure drop created as the fluid passes through a restriction, such as an orifice plate, venturi tube, or flow nozzle. Based on Bernoulli’s principle, the difference in pressure before and after the restriction is proportional to the flow rate.
These flow meters are highly versatile and can be applied to liquids, gases, and steam across a broad range of pressures and temperatures. They are commonly used in industries such as oil and gas, water treatment, chemical processing, and power generation.
