Oct 11, 2022 · Differential Pressure Flow Sensors Differential pressure flow sensors are the most popular type due to their cost, performance, and versatility. These sensors have a flow body of known cross-section, that includes a built-in restriction, such as an orifice plate. The restriction creates a difference between the upstream and downstream pressure.
