Can anybody suggest me with a formula to calculate flow from annubar sensor ?

are these formula correct ?
ACFH = 358.94*K*(D^2)*sqrt(hw/rho) ?
where
K = koeffisien
D = pipe inside diameter
hw = DP accross annubar
rho = gas density

the fluid is natural gas.

rgrds,

You mention Annubar: you must be seating on the catalog, where all what you need is there, read. In the worst case contact your distributor
in case your fluid is i doubt.

 

What is ACFH? is DP Differential Pressure?
