Differential Pressure Flow Meters

Differential pressure (DP) flow meters measure the flow rate by calculating the pressure drop over an obstruction/restriction inserted in the flow path. This technology is based on the Bernoulli Principle and is one of the most common and versatile methods for flow measurement. DP flow meters are suitable for a wide variety of fluids, including gas, liquids, and steam, making them a staple in industries such as chemical, petrochemical, and energy industries.

DP flow meters are favored for their accuracy, reliability, and ability to measure flow in challenging conditions, including high temperature and high pressure environments. They can be configured with various primary elements, such as orifice plates, venturi tubes, and flow nozzles, to suit specific application requirements. Although they require a pressure drop to function, advancements in design have led to more efficient models that minimize energy loss, making them more suitable for energy-conscious applications.
