1. TRANSDUCER LOCATION
A. In general, select a mounting location on the piping system
with a minimum of 10 pipe diameters (10 X the pipe inside
diameter) of straight pipe upstream and 5 straight
diameters downsteam. The installation location should
also be positioned so that the pipe remains full when the
liquid is flowing through it. On horizontal pipes the trans-
ducers should be located on the sides of the pipe. See
Figure 1.2. See Table 2.1 for additional configurations.
B. Select a mounting method, Figure 1.1, for the transducers
from Table 2.2, based on pipe size and liquid
characteristics. In General, select W-Mount for plastic and
steel pipes flowing clean, non-aerated liquids in the 1-6
inch [25-150 mm] internal diameter range. Select V-Mount
for pipes of all materials and most liquids in pipe sizes from
3-10 inches [75-400 mm]. Select Z-Mount for pipes larger
than 10 inches [400 mm].
C. For each measuring channel integrated into the TFXM, en-
ter the parameters listed in Table 1.1 via the TFXM keypad
or UltraLink software utility.
D. Record the value calculated and displayed as Transducer
Spacing/XDCR SPC.
