How a differential pressure transmitter is used to measure the flow of a gas or liquid in a closed pipe.
This video guide explains the different types of primary elements used to measure flow and how they produce a differential pressure which can then be converted to a linear measurement of flow from calculating the square root of the pressure. It also covers the ways to install a DP transmitter on different types of media flow.

This overview of the workings of a DP cell, guides you through the various mechanical components such as the functional purpose of the process isolation diaphragms, the oil fill and the capacitance sensing element.
