What will be the new flow factor if a DP transmitter is re-arranged from 25 kPa to 50 kPa?

A simple calculation is as follows:

        Q1/Q2 = Sq root of DP1/ Sq root of DP2

        Q1 = Q2 * Sq root of DP1/ Sq root of DP2

Q1 = New flow factor, Q2 = Existing flow factor

DP1 = Transmitter new range, DP2 = Transmitter existing range

                    Q1 = Q2*SQ ROOT OF 50/25

                    Q1 = 1.41*Q2

The new flow factor will be 1.41 times higher than the existing flow factor.
