Insertion of PVDF Probe
Longer probes are coiled and have numbered tie
wraps. When installing probe, cutting tie wraps
in sequence helps to prevent the installer from
accidentally twisting the probe.
1. Two people are needed, one to hold the assembled section of
the probe and guide the probe into the tank, and the other to
keep the coils parallel and unwrap them in sequentially.
2. Thread bushing into tank or flange. Bolt flange into
position.
3. Thread compression fitting into bushing or flange.
4. Hand tighten. To insure compression fitting is sealed, turn
the fitting 1 ¼ turns after hand tightening. Do not over
tighten compression fitting if it is being used.
5. Make final check to see that all of the bolts and screws are
in proper position and probe is securely tightened.
A second person is
recommended to support
loops so they do not kink
18
Snip tie-wraps ONLY as sensor is
guided into vessel to avoid
unraveling & kinking of sensor.
Do NOT allow coils to separate and become
perpendicular... This twist will damage the
Wave Guide within!
