Installing the Chemical-Resistant Models
The sensor may be threaded directly into the side of a tank (see dimensions for hole diameter and thread specifications),
or into a non-threaded hole, using the included threaded nut. Recommended through-hole size: 56.5 ± 0.5 mm.
For a non-threaded hole, install an o-ring onto the flange, and insert the flange completely into the hole until the sensor
front surface is against the tank’s exterior surface. Place the other o-ring into the groove on the Teflon nut, and thread the
nut onto the flange. Tighten enough to eliminate gaps between the flange and the tank surface. This will ensure that the o-
rings are fully compressed.
