Round coils of extra flowmeter cable in the pump
compartment act as an antenna. While the
flowmeter cables cannot be shortened, various
lengths of premolded cable are available to minimize
the “extra” cable in the truck. (See parts list in
Section 7 for part numbers of different size
flowmeter cables). When routing flowmeter cables,
take care to avoid routing them next to antenna
cables, radio power lines and radio components.
When there is extra cable, double the cable back on
itself and secure in a flat bundle with plastic wire ties
instead of making round coils (see Figure 8).
Install clamp-on beads at the locations indicated in
Figure 7. Use a small amount of RTV silicone,
electrical tape or heat shrink tubing to keep the
beads from moving after installation. The clamp-on
beads must be slid up as close as possible to the
connectors on the cables.
The flowmeter tees may also need grounding. If
metal piping is used, sufficient grounding may be
present. However, victaulic joints, plastic pipe and
rubber-mounted pumps interfere with proper
grounding, and an additional ground strap is
required. Connect a braided ground strap at least
1⁄4" (6 mm) wide from the flowmeter tee to the
apparatus frame to ensure proper grounding. A #6-
32 UNC tapped hole is provided on the flowmeter
tee for attaching the ground strap.
