Side Mount Installation
A side mount low tank level
sensor is used if the bot-
tom of the foam tank is not
accessible.
1. The sensor has
1/2” (13mm)
NPT threads. If
tank design and
construction
allows, the side
mount sensor is
threaded
directly into the
side of the tank
at the proper
height. (See
Figure 3-38:
“Side Mount
Sensor Loca-
tion Dimen-
sions.”)
Also, the sensor can be mounted on the foam tank using a 1/2” x 1” (13
x 25mm) NPT bushing and a bulkhead fitting with 1” (25mm) FNPT
threads.
2. The center of the switch must be located at least 1-½ to 2 inches (38 to
51 mm) from the bottom of the foam tank with the float positioned on top
of the switch to allow up and down movement.
