Typical Installation
Mount Options
Identify a threaded opening on the top of the tank for
the sensor. The location should be vertical with a clear
path to the contents of the tank. There should be no
obstructions that could interfere with the signal.
1. If the hole is not threaded, place the foam gasket
(included with kit) over the opening.
2. Place the mounting adapter (included with kit) on
top of the foam gasket.
3. Use the two (2) stainless steel self-tapping,
counter-sunk screws (included with kit) to attach
the adapter to the tank. Do not over tighten.
4. Attach the sensor to the adapter. To form a secure
seal, make sure that the sensor is vertical on the
tank, that it is secured correctly to the base, and
that the threads have not crossed.
NOTE: If the tank does not contain a suitably positioned
opening at the top of the tank, reference Drilling, page
