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.
Why is flow measured in square root?
Generally, the flow transmitter is configured in square root because a small change in differential pressure on the lower end results in a large change in flow. If the square root is considered in the controller, the large change in flow makes it extra sensitive to electrical noise on the mA 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.
