1. MEASURE AND MARK
(TVMSDBWK-001 Only)
CAUTION
Any Sensors positioned close to corners of the
tank must be at least ½" (12.5 mm) away from the
curvature of the tank, i.e. The centre of the probe
must have a radius of at least at ½" (12.5 mm) of
flat surface to mount on.
½"
(12.5 mm)
On the side of the tank, measure out the Sensor
positions, starting with the top Sensor at the 80%
mark, then 60%, 40%, and 20%. Position the
bottom Sensor as close to the bottom of the tanks
as possible — Note that this means that the spacing
between the Sensors may not all be equal.
Note:
the Sensors do not have to be mounted in-line.
The example shown ('Front' view) is acceptable.
Before drilling, check each marked location for good
access and confirm face is flat both outside and inside
at least 1" (25 mm) around each position.

2. DRILL
(TVMSDBWK-001 Only)
Ensure tank is empty of liquid before drilling holes.
Using a sharp
3
⁄
8
" (or 9.5 mm) drill bit, drill each marked location at
slow speed. Ensure the cut is clean (de-burr inside and out) as any
irregularities will prevent a good seal.
Note:
Using a drill bit greater than
3
⁄
8
" (or 9.5 mm) in diameter may
prevent the Sensors from sealing properly, resulting in leaking.
3. INSERT SENSORS
(TVMSDBWK-001 Only)
For each Sensor,
remove the top nut.
At each location, gently push the Sensor
through the drilled hole until the rubber
stopper is flush with the outer tank
surface.
Tighten the nut to form a waterproof seal
(the rubber is squeezed against the inner
wall). Torque to 0.5 lbf-ft (0.7 Nm)
