Orifice meter runs are used for measuring the flow at higher accuracy.
The orifice meter runs are therefore, not the ones simply weld pipes to upstream and downstream
sides or an orifice assembly, but the ones welding smaller inside diameter pipes to smaller diameter of
flanges, then, finish inside diameter or the pipe / flange assembly by boring or honing to the specified
dimensions with the required tolerances and surface roughness
