Why use square root extractor?
Why use a square root extractor? The flow rate along a closed pipe is directly proportional to the square root of the pressure drop across a measuring device e.g. orifice plate, in the pipe, and it is estimated that around 50% of all flow measuring applications still use differential pressure to infer flow rate.
What is square root extraction?
Square Root Extraction is a mathematical process which is applied to a linear measurement scale to convert it to a non-linear square root scale. The square root scale is generated by taking the square root of the ratio between measurement reading and full span.
