I am working with a DCS control system, and I need to extract the square root of a flow transmitter. It's a very simple procedure, but I have some doubts.
1) According to Bernulli law, the output from the flow transmitter is a square root, right?
2) In the control system, the function I have to use do the following calculation:
sqrt (input/100) * (Span high-Span low) + Span low
If the output from the flow transmitter is a square root value, using this function I am applying another square root to the signal.
Hope someone can help me.
Thanks.
