Comprehensive Overview of Differential Pressure Flow Meters

Pressure Transmitter /

1. Fundamental Principle Differential pressure (DP) flow meters operate on the throttling principle, derived from the Bernoulli equation. They calculate flow rate by measuring the static pressure difference generated as the fluid passes through a restriction (such as an orifice plate or venturi tube), and combining it with known physical parameters. 1.1 Working Principle When
