Chapter 2. Installation

Slide the second mounting block to the calculated spacing plus the initial scale number selected for
the first mounting block. (For example:
a. Initial convenient number for the first mounting block =
5 cm or 2 in.
b. Spacing as calculated by the GC868 = 0.5 in. or 12.5 mm
c. Second mounting block final location = 2 + 0.5 in. = 3.5 in. or 5 cm + 1.25 cm = 6.25 cm
The overall spacing between yokes should be left edge to left edge, or right edge to right edge. Figure 28
below shows typical positioning.

In a similar manner, install the second transducer as shown in Figure 28 above.
2.9 Installing the PI Fixture and Transducers
The PI clamping fixture holds transducers on pipes from 12 to 24 in. in diameter. It comes with either a chain
or strap, depending on the selection made with the initial order from GE. To install the fixture and
transducers, complete the following steps:
2.9.1 Surveying the Pipe
1.
Measure the pipe circumference to an accuracy of ±2 mm (±1/16 in.)
IMPORTANT: Do not use a calculated value or a nominal value for the circumference.
2.
Tightly wrap the layout wrap once around the entire pipe and line up the edges. Using the wrap as a
template guide for marks, mark scribe lines around the entire diameter of the pipe, as shown in
Figure 29 below.
