Tank Alert
Ultrasonic Liquid Level Monitor
Installation Instructions
TankAlert monitors and displays liquid levels and
gives an alert when the level drops below 5% of
tank height. There are 2 product
types (1) Transmitter (no display
- 2 versions as in diagrams
above) + Receiver and (2)
Transmitter with Visual display
(allows user to view liquid level
at tank) + Receiver; please follow
the installation instructions for the correct type.
Fuel & Tank Types
Preparing the Tank1
a) To avoid error, the TankAlert transmitter must
sit in a vertical position on top of the tank and
have a direct line of sight to the liquid level in
the tank, through to the bottom without any
interference from e.g. window configurations or
tank braces.
b) Install the supplied metal adapter into the
pre-drilled 2” NPT opening on the top of the
tank. Apply pipe sealant on the adapter thread
and tighten appropriately. For basement tanks,
temporarily place a rag/cover over the adapter
to minimize fuel odors until transmitter is
synchronized. Tanks with 1½” and 1¼” NPT
openings or European style double-wall tanks
require adapters. Do not use an extension pipe
when mounting the adapter; this can cause
inaccurate measurement and malfunction.
c) Installation Help:
Avoid tank braces and tank windows.
Setting the
Switches on
the Receiver
3
Activate the switch (located at back of receiver)
numbers that correlate to your tank size (see
chart at Step 9 overleaf) by using a screwdriver or
ballpoint pen to move the switches upwards to the
ON position. Activating switch 1 (the audible ring
feature), enables a bleep to indicate a low-level
reading (< 5% liquid warning).
Matching Receiver
and Transmitter for
both visual and
no-display types.
4
You can now link/match the receiver to the
transmitter, through getting a unique code for your
tank (this need only be done once, at installation).
• Plug receiver into a convenient electrical socket
and switch on.
• The display screen on the
front of the receiver will show
a flashing top bar as shown in
diagram (opposite) for up to
2 minutes indicating that the
transmitter can be matched to
the receiver during this time.
• Hold the transmitter (left side) against the
receiver’s right side so that the black dots on
each are aligned (for 20 seconds). This allows
the unique code to be transferred. During the
matching process, you will hear an audible beep
from the receiver to indicate matching is in
progress. The number of bars will increase on
the receiver display until all 10 bars are flashing
and an audible beep occurs: this indicates that
the unique code has been transferred. The setup
is now complete for the no-display type only;
the transmitter is now ready to read and transmit
liquid levels and must be placed on the tank
immediately (Step 6).
• If matching visual (LCD display) transmitter, you
MUST continue to hold the two units together
and proceed to the next stage of the matching
process (Step 5 across).
Additional Matching Step To Calibrate
Visual Transmitter to Tank Height
(TankAlert Visual ONLY)
5
When using TankAlert Visual, the visual transmitter
must also be calibrated to the tank dimensions. so
that liquid levels can be read at the tank as well as
in your home.
To do this, you MUST continue to hold the
transmitter and receiver together (via the black
dots) after the ten bars are showing on the
receiver (post Step 4).
Continue to hold the black dots together until the
visual transmitter screen goes blank. A nozzle
icon will flash in 10 seconds, indicating that the
transmitter is in ‘tank height setting’ mode. Continue
to hold as the black bars increase until the number of
black bars, according to the table below, increases to
match the height of the tank measured at step 2.
When the number of bars indicates the correct tank
height, immediately separate the transmitter and the
receiver.
Define Tank Height2
Accurately measure the height of your tank from
the liquid outlet at the bottom of your tank to the
bottom of the TankAlert ultrasonic monitor. TankAlert
measures the level of usable liquid in the tank in 10
graduations of the tank height. Correct tank height
measurement is critical for accurate liquid level
display.
Wait for a double flash of the red light on the visual
transmitter to indicate that the tank height setting
has been stored in the transmitter. The transmitter
can now be placed on the tank.
There may be one bar more or less displayed on the
visual transmitter display compared to the receiver
display when operational. This is due to the smaller
number of tank height settings that may be selected
with the transmitter screen bars compared with the
receiver switches. The bars in both displays will
accurately reflect the level in the tank.
Note: if the number of bars displayed overruns
the height setting table (below), continue to
hold the black dots together until the screen
returns to blank and the nozzle flashes; re-start
the process again until the correct number of
bars appear.

TankAlert can be used on all standard steel tanks. To work
optimally, tanks must be placed on a level surface, be a
maximum height of 10 feet and be within
a 450 ft./150-meter line of sight of the
receiver.
