Secondary Elements for DP Flow

What Is a Differential Pressure Flowmeter?

Differential pressure (DP) flowmeters measure flow in a closed pipe using Bernoulli's equation. The technology consists of two to three elements. The primary element creates a pressure drop so the secondary element, the DP flow transmitter, can measure the differential pressure flow. Differential pressure flow measurement devices offer benefits such as simplicity, low cost, versatile installations and gas/liquid uses, and familiar maintenance processes.

A muitvariable (mass flow) or differential (volumetric) pressure transmitter is considered the secondary element for a differential pressure flowmeter set-up.
