Answer / amit uapdhyay

it is a critical parameter of designing of orifice. & it must be not greater the .7

unit less a factor defined as === d/D

D- pipe dia
d- orifice plate hole dia.

Answer / rampal

Beta is a ratio of orifice dia to inside pipe dia.

Beta = d/D

Answer / r_vaya

Beta Ratio is the Ratio between the line inner diameter to bore size of the orifice.

Orifice dia / pipe dia 

The flow coefficient is founds to be stable between beta ratio of 0.2 to 0.7 below which the uncertainity in flow measurement increases.
