Implementing the square root
Implementing the square root
(OP)
Dears all,
Happy new year to all,
Today I have a discussion with our engineering team in our Petrochmical plant regarding implementing the square root in the Local feild transmitter or in the DCS (( System ))
Please can any one advise what is the advantage and disadavantage for each princible, and what is the best from control point of view.
Your reply is highly appreciated.

RE: Implementing the square root
If the instrument is known as a flow transmitter, why not have its output directly in flow values/units rather than pressure values/units?
My opinion is that if the process variable is flow, I'd rather view (square rooted) flow values in the local display than pressure values, but that's just me.
I'm not aware if any inaccuracy issues one way or the other. Maybe someone else does.
