商品説明

The LV150 Series high level
indicators provide a unique solution
for tank overfill indication requiring
self-checking. This indicator is
designed with a 2" NPT mounting,
making it ideal for use in
underground and aboveground
storage tanks. When mounted
vertically at the tank top, it reliably
indicates high liquid level.
To operate, simply press the brass
tube fitting down to perform the
self-check test. This manual
operation physically moves the
inner reed switch assembly while
the float remains stationary (wet or
dry). By doing this, the switch logic
is inverted, checking the integrity of
the circuitry without the need to
remove the unit from the tank.
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 LV150 Series is offered in
integral one foot lengths. For other
lengths, adaptor systems are
available. They consist of 2 parts:
the LVR-C6S coupling
(2 x 2" FNPT) and an LVR-6S 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.
