Mounting

The LV160 Series high level
indicators have a 2 NPT mounting,
making them ideal for use in
underground and aboveground
storage tanks. When mounted
vertically at the tank top, the unit
reliably indicates high liquid level.
The unit’s rugged construction and
multiple design options make it
adaptable for just about any
environment. The indicator is
available in brass or stainless steel,
making it suitable for use with a
wide range of liquids.

Adjustable versions are available for
varying tank sizes. A special cinch
nut on the mounting allows the stem
to travel up or down to fine-tune
actuation points. The extent of the
adjustment depends on the unit’s
length and distance from the
mounting to the highest float stop.
The LV160 Series is offered in
integral 1 foot lengths. For other
lengths, adaptor systems are
available. They consist of 2 parts: the
LVR-CBR coupling (2 x 2 FNPT) and
an LVR-B pipe nipple (2 x 2 MNPT)
of various lengths to change the
insertion depth of the sensor. When
using the adaptors, retaining clip
pliers are required to remove the
float for installation.
