Question: What is differential pressure transmitter working principle?

Any difference of pressure across the cell causes the diaphragm to flex in the direction of least pressure. The sensing diaphragm is a precision-manufactured spring element, meaning that its displacement is a predictable function of applied force.

What is differential pressure principle?

The operation of differential pressure flowmeters is based on the concept that the pressure drop across the meter is proportional to the square of the flow rate; the flow rate is found by measuring the pressure differential and taking the square root.

What is meant by differential pressure transmitter?

A differential pressure transmitter is an instrument that can consistently and accurately create a pressure drop in a pipe and then use the pressure measurement on either side to provide the rate of flow within the pipe. A differential pressure flow transmitter can be easily installed in many applications.

What is a differential pressure transmitter used for?

Differential pressure transmitters (also called DP transmitters) are among the most versatile measuring instruments. In addition to pressure, they are used to measure level and flow in many industries, on a wide variety of fluids even at high temperatures.

How differential pressure is measured?

Differential pressure – the third method of measuring pressure – is simply the difference between two applied pressures, often referred to as delta p (Δp). In the example, Δp = p1 – p2.
