What is square root in flow transmitter?

What is the transmitter square root function and why you should use it? It is a function on differential pressure (DP) transmitters that calculates the process flow using differential pressure readings.

What is the square root signal?

As you can see from the table, the square-root relationship is most evident in comparing the input and output percentage values. For example, at an input signal pressure of 6 PSI (25%), the output signal percentage will be the square root of 25%, which is 50% (0.5 = √0.25) or 9 PSI as a pneumatic signal.

What is square root extraction in flow measurement?

What is square root extraction? Square Root Extraction is an arithmetical conversion which is applied to a linear measurement scale to convert it to a non-linear square root scale. For example, a square root extractor is used to convert a linear differential pressure signal to a non linear flow rate.
