This sensor has a float which rises and falls on the central shaft with the level of liquid in the tank.
The sensors are fully insulated to protect against dangerous electric currents inside the tanks.
This is an extremely important safety feature, because it protects against electrolytic corrosion, as well as the danger of an explosion.

The thread is 1-1/2" NPT, tapered male National Pipe Thread.
Retro-fit/replacement installations will generally use the existing mounting hardware.

For new installations, a user supplied 1-1/2" female NPT fitting will need to be mounted on the tank.

The sending unit length is measured from the top of the threads to the tip of the gauge.
It should be at least 1" less than the depth of a plastic tank, and 3/4" less than the depth of a metal tank.
Note: if the top of your metal tank flexes, deduct one (1) inch from the depth (like a plastic tank).
