2.1.2 Channel Supports
Channel supports, being typically straight, are normally used with rigid transducers. A channel
support consists of a straight channel with loop supports mounted at intervals. The loop supports
are required to keep the transducer within the channel. Figure 2-5 shows a channel support.
Channel supports are available from various manufacturers or may be fabricated.

2.1.3 Guide Pipe Supports
Guide pipe supports are normally used for flexible transducers. A guide pipe support is construct-
ed of non-ferrous material, straight or bent to the desired shape. As shown in Figure 2-6, both
inside and outside dimensions of the pipe are critical:
• Because the transducer rod is installed inside the pipe, the inside diameter of the pipe must be
large enough to clear the rod.

Guide Pipe Support
• The outside diameter of the pipe must be small enough to clear the magnet.
Refer to pipe manufacturers’ specifications and dimensions (schedule 10, 40, etc.) to select the
appropriate size pipe. Guide pipe is typically supported at each end of the pipe.
