Why does use square root output for flow in dp tx ?

Question

Accepted Answer

The square root output is used for flow in dp tx to linearize the relationship between flow and pressure.

Square root output is used to compensate for the non-linear relationship between flow and pressure.
It helps to convert the pressure measurement into a linear flow measurement.
This is done because the pressure drop across an orifice or a flow element is proportional to the square of the flow rate.
By taking the square root of the pressure measurement, the resulting output becomes directly proportional to the flow rate.
This linearization allows for easier interpretation and control of the flow measurement.

Accepted Answer

Become flow is directly proportional to the square root of dp
