Model 7100V Flex Probe
The 7100V Flex Probe (Figure 4-3) utilizes the same magnetostrictive
technology for above ground tanks up to 50 feet (15.2 m) in height. It is
important to follow the handling instructions to avoid damaging the probe
and voiding the warranty. During the unpacking and installation of the
Model 7100V Flex Probe, always keep the diameter of the coils between
40 and 48 inches (about 1 m).
Flex Probe Installation Requirement:
Flex probe head/wiring must be installed in weatherproof junction box
with seal packs for wiring connections. Failure to comply with these
requirements may invalidate probe warranty.
