Installing the PrimeProbe2
Once the boss/valve is installed, insert the PrimeProbe2 into the pipe. To
do this, first determine whether to install the PrimeProbe2 on the centerline
of the pipe (1/2-pipe) or at the mean velocity point (1/8 or 7/8-pipe).
Centerline installation is the preferred method because it allows for a
greater margin of error if installation does not occur exactly on the
centerline. Choose the 1/8- or 7/8-pipe (mean velocity) method only when
the PrimeProbe2 is not long enough to reach the centerline or the flow
velocity is excessive.
Use caution when using 7/8 insertion on larger diameter pipes because
excessive velocity can bend the instrument.
