Question: Is the flow calculation completed with just the sqrt (Dp)? Or the sqrt(Dp) has to be multiplied with factors (e.g discharge coefficient, comprecibility factor) derived from the orifice calculation sheet?

If it's the latter, which is the formula that has to be implemented in the software of DCS? For information, the DPT is from Yokogawa and the orifice is from another manufacturer.

I don't refer to pressure-temperature compensation which is done nevertheless, just the sqrt(Dp)-flow calculation.

Thanks in advance
