Installation
Set Up
Register TLM to Tank in Pulse
Level Software
Navigate to URL: level.gracopulse.com
This device requires access to a cellular network to
work, and can be activated in Pulse Level. Refer to
Pulse Level terms of service in the About section of the
software.
After creating user, organization, branch and site,
navigate to Devices (located in the upper right corner of
the screen). Associate the device to your organization
by entering the serial number. When you create a tank
for the site, the device will be assignable.
Assign the TLM serial number to a tank in Pulse Level.
Activation
1. Hold the magnet (supplied) to the Hot Spot directly
under the LED to activate the device (FIG. 1).
2. Keep holding the magnet to the Hot Spot. The LED
will flash green, and then flash red. Then the red
light will stay lit.
3. Remove the magnet.
4. While the red light is illuminated, a series of beeps
occur as the device connects.
5. Successfully connecting is indicated by a
high/low/high series of beeps that indicate the data
is being sent to Pulse Level. The LED turns green
after data is successfully sent.
6. Once activated, the device uploads readings at
scheduled times, if assigned to a tank in Pulse
Level.
• The device measures the tank liquid level.
NOTICE
• Do not over tighten TLM into tank bung. Over
tightening can cause permanent damage and
result in inaccurate readings.
• Do not use the TLM with pressurized tanks. Using
the TLM in a pressurized tank will damage the
TLM.
• Do not use thread sealant or adhesive. Many of
these products are chemically incompatible with
the ABS plastic.

Typical Installation
Mount Options
Identify a threaded opening on the top of the tank for
the device to be installed. The location should be
vertical with a clear path to the contents of the tank.
There should be no obstructions that could interfere
with the signal. Insert the threaded device by screwing
it into the opening. Do not over tighten.
1. If the hole is not threaded, place the foam gasket
(included with kit) over the opening.
2. Place the mounting adapter (included with kit) on
top of the foam gasket.
3. Use the two (2) stainless steel self-tapping,
counter-sunk screws (included with kit) to attach
the adapter to the tank. Do not over tighten.
4. Attach the device to the adapter. To form a secure
seal, make sure that the device is vertical on the
tank, that it is secured correctly to the base, and
that the threads have not crossed.
NOTE: If the tank does not contain a suitably positioned
opening at the top of the tank, reference Drilling,
page 4.

Installation Examples
Drilling
If the tank does not contain a suitable positioned
opening at the top of the tank, it will be necessary to
manually drill into the top of the tank.
1. Select a flat area on the top of the tank located
towards the center (FIG. 3).
2. Drill a 1.5 in. bsp hole at the selected area using a
45.5 mm tapping drill.
3. Continue with Activation.

Operation
View Data
The TLM is configurable with Pulse Level
(level.gracopulse.com) to take readings at predefined
times.
After configuring the TLM using the Pulse Level, apply
the magnet to the hot spot until a solid red light
appears, creating a connection between the TLM and
the Pulse Level to load the configuration (FIG. 4).
NOTE: Frequent measurements results in shorter
battery life.
Manual Measurement
1. Hold the magnet (supplied) to the Hot Spot directly
under the LED to activate the device (FIG. 1).
2. Keep holding the magnet to the Hot Spot. The LED
will flash green, and then flash red. Then the red
light will stay lit.
3. Remove the magnet.

Troubleshooting
3A8551E 7
Troubleshooting
Problem Cause Solution
Device is not reporting scheduled
readings.
Out of RF range.
RF obstruction.
Consider implementing a WiFi
network and using Graco’s WiFi
TLM.
Ensure that the TLM is not encased
in metal, since this would obstruct
the signal.
Weak or dead batteries. Replace batteries. See Replace
Batteries, page 8.
Tank Level Monitor was not
associated with a tank in software.
Assign TLM serial number to tank.
Reading is scheduled when pump
is operating.
Ensure readings are scheduled
during times that the pump is not
operating.
LED will not turn on. Magnet removed too soon. Hold magnet to device hot spot for
a longer period of time.
Try using a stronger magnet.
Weak or dead batteries. Replace batteries. See Replace
Batteries, page 8.

Service
8 3A8551E
Service
After the TLM has been installed, the only additional
maintenance or service necessary is changing the
batteries.
Replace Batteries
NOTE: After battery placement, activate the TLM with a
magnet (see Activation, page 2), to synchronize the
TLM internal clock to maintain scheduled TLM
readings.
1. Remove the TLM from the tank by unscrewing it
from the opening.
2. Remove the four (4) screws that keep the case
together (FIG. 6).
3. Verify that the device is right side up before
opening to prevent the batteries from falling out
(FIG. 7).
4. Replace the four (4) C-cell Alkaline batteries
(FIG. 8).
WARNING
Fire and Explosion Hazard
Sparking can occur when changing batteries. Only
replace the batteries in a non-hazardous location
away from flammable fluids and fumes.
