Differential Pressure Flow Meters for Gas: Key Applications in Oil & Gas and Power Industries
Differential pressure (DP) flow meters are among the most widely used flow measurement technologies in industrial applications, especially in the oil & gas and power generation sectors. These devices operate on the principle of Bernoulli's equation, measuring the pressure drop across a constriction in a pipe to determine the flow rate of gases. Due to their reliability, cost-effectiveness, and compatibility with high-pressure and high-temperature environments, DP flow meters remain a preferred choice for gas flow monitoring in critical processes . One of the most common types of differential pressure flow meters is the pitot tube flow meter , which measures the difference between total pressure and static pressure to calculate gas velocity. This device is particularly useful in large ducts or stacks where insertion-type measurement is preferred. Its simple design and low maintenance make it ideal for monitoring flue gas flows in power plants or ventilation gas distribution in...
