Hi,

Suppose I have to install Orifice plate in a line for which I know the Line Size, Flow range, Pressure Range, Operating pressure & temperature range. As well as Viscosity. How can I calculate the Orifice detail? How can I calculate dp, beta ratio? Do you know some software where u feed the detail you know and it will calculate the beta ratio & dp? and orifice thickness? I mean free software. Please help me. I need it urgently.

A couple of sources for rigorous calculation procedures are:

R.W. Miller / Flow Measurement Engineering Handbook / McGraw-Hill
ASME standard MFC-3M-1985 or the latest version

There are many other less precise procedures also available

Daniel flow has a downloadable flow orifice calculator that is menu driven and very to use. Daniel is a division of emerson electric.
 
muthuraman,

A more precise assembly of calculations can be found in " L. K. Spink's "Principals and practice of flow meter engineering".

These are user friendly and directed at the plant floor.
