All pipe types and sizes
Select a pipe location that provides a minimum straight length of pipe of at least 10
times the pipe’s nominal pipe size and mark a point that is at least 5 times the pipe
diameter downstream from the nearest pipe fitting. See section 1.6 for the minimum
straight pipe length requirements.

Measurement
“V” Mount Mode
Typically smaller pipe
sizes from 2” to 6”
diameter.
“Z” Mount Mode
Typically larger pipe
sizes from 4” to 100”
diameter.
The optional T-Track mounting system may be used for transducer installation. T-Track
installation is described in a separate manual.
V-MOUNT
T-TRACK MOUNTING SYSTEM
If the fluid contains little or no particles (up
to 10% maximum), operate the meter using
the Transit Time method to obtain the best
accuracy. Select “V” mounting mode when
possible. The “V” mounting mode allows the
greatest sound travel distance while
permitting good signal strength. Basic pipe
material and size general guidelines are
shown below.
If the fluid to be measured contains
particles, the meter should be operated
using the Doppler measurement method.
For Doppler operation, the transducers will
be mounted directly opposite each other as
shown below.
