Regarding the squaring issue of differential pressure flow meters.

There is a question: is the formula for the differential pressure transmitter, Q/Qmax = √ΔP/√ΔPmax = √I/√Imax, correct? Also, when taking the square root, is it taken of the percentage, or of the differential pressure, or of the 4-20mA signal? I hope an expert can help clarify this.

Ratio of differential pressure to differential pressure range X flow rate range = flow rate squared root of percentage
