Installation
2.5.3
Before Insertion of PVDF Probe
At this point, if probe span is to be set outside the vessel,
then go to Section 2-9 Setting Span before continuing...
BUT READ THIS FIRST!
If necessary to set the span outside of the tank, take extra
precaution to avoid damaging the flexible probe. Note that the
longer probes are coiled and have numbered tie wraps.
If you uncoil the probe outside of the tank to set the zero and
span, it is important to recoil the probe, before installation. The
probe coil should be approximately 48 inches in diameter and
the coils should always remain parallel with each other.
If you lift a coil perpendicular to the rest of the coils, you can
kink the probe. The kink generally cannot be straightened out
and results in damage to the Wave Guide in the tube.
Kinking is considered user damage and is NOT covered
under warranty!
Numbered Tie Wraps
Supporting tie wraps are numbered in the order that they must
be removed to avoid damage to Flexible PVDF coil.
See section 2.5.4, typically a second person is recommended to
avoid improper bending of PVDF tubing during installation.
