2.0 Location and orientation
Install the Rosemount 1195 Integral Orifice in the correct location within the
piping branch to prevent inaccurate measurement caused by flow disturbances.
2.1 Straight pipe length
Use the upstream (U) and downstream (D) lengths provided below in conjunction
with figures below to determine the appropriate upstream (U) and downstream
(D) pipe lengths. For example, for a 1-in. line size with a beta ratio (β) of 0.4 using
installation of Figure 4, the straight length of upstream piping required is
25 ⫻ 1 = 25-in., and downstream 10 ⫻ 1 = 10-in.
Note
The Rosemount 1195 Integral Orifice comes with the associated pipe lengths (18D
upstream and 8D downstream) when ordered with process pipe-end connections.
