How do you find the square root of a flow transmitter?
Logic for Taking the Square Root in the Controller
But the root of a number from 0-1 is larger: √0.5 = 0.707. So if you have a 12 mA signal from the DP cell, that's 50% DP, but 71% flow rate. Multiply the resulting square rooted signal (still 0-1) by the flow scale span to get flow rate in engineering units.
How is flow measured in square root?
Square root extraction in flow measurement is an arithmetic conversion applied to a linear measurement scale to convert it into a nonlinear square root scale. The square root scale is generated by considering the square root of the ratio between measurement reading and full span.
How do you calibrate a square root transmitter?
In order to calibrate, you should simply move the first calibration point a bit higher than 0% of the input range. If the first calibration point is at 5 – 10% of the input range, you are already out of the steepest part of the curve and you can get reasonable readings and error calculation.
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.
