2.5.6 Even and Odd-Traverse Installations

The transducers for a PT900 system may be installed in either of the following
configurations:
•
Even-Traverse
flow an even number of times before being received by the other
transducer (two traverses is recommended for most applications).
•
Odd-Traverse
flow once or an odd number of times before being received by the other
transducer.
2.5.6a Even-Traverse Installations (Spacing <305 mm/12 in.)
The standard PT900 clamp-on fixture is designed for an even-traverse installation,
as illustrated in Figure 23 below. After mounting the clamp-on fixture on the pipe,
refer to "Viewing the Transducer Spacing" on page 73 to adjust the spacing of the
transducer clamps to the required axial distance.

Important: The installation above assumes a transducer spacing of
<305 mm/12 in. For even-traverse installations with transducer
spacings >305 mm/12 in., see "Even-Traverse Installations
(Spacing>305 mm/12 in.)" on page 28 for instructions.
