Battery Pack Replacement
The tank monitor that is installed on your bulk storage tank is fitted with an easily
replaceable battery pack. The procedure below outlines the steps necessary to change a dead
battery pack.
1. Secure a ladder to the bulk tank that has the Sentinel tank monitor with the dead
battery pack.
2. With one hand, grab hold of the Sentinel tank monitor. With your free hand,
carefully unscrew the black plastic top.
3. Locate the battery pack inside the monitor. Unplug the orange two-pin connector,
and remove the battery pack.
4. Holding the monitor firmly with one hand, insert the new battery pack into the
monitor, and connect the new battery pack into the orange two-pin connector.
5. Locate the Sentinel’s black antenna, and insure that it is tightly connected to the
monitor, and is pointing straight up.
6. With the cover still removed, locate the small white pushbutton located near the top
right corner of the monitor’s circuit board (opposite side of the orange two-pin
connector; refer to illustration below).
7. Press and hold the little white button until a green LED lights up. The green LED
will flash fast (half second ON, half second OFF).
8. Upon establishing a link with the Base Station, the green LED will flash slow (one
second ON, one second OFF).
9. When a command is received from the Base Station, the green LED will go to solid
ON for about 10 seconds. This is the actual transmission of data to the SupplyNet
Base Station.
10. After a successful transmission, the green LED will flash once ON and OFF, then
extinguish. The Sentinel is now in passive mode, and will remain in passive mode
until the next scheduled transmission time, or when the little white button is pressed
and held again.
11. If the data transmission was not successful, a red LED will flash once, followed by
up to ten green LED flashes. The number of green LED flashes following the red
LED flash corresponds to an error code. Please note the number of green flashes.
12. Note the time the LED went to solid ON (the actual data transmission). Contact the
SupplyNet Monitoring Center at 888-826-5546, ext. 713 to verify a successful data
transmission, and to verify the product level, so we can insure the monitor is working
properly.
13. Replace the black plastic to onto the Sentinel finger tight.
14. Congratulations!! You have successfully replaced a dead battery pack.

Final Testing
Once all tank preparation has been completed, the Sentinel is properly mounted to the
tank, the signal strength has been verified and the number of callouts per day has been
properly set, it is now time to establish communications with the SupplyNet Monitoring
Center.
1) With the top black cover of the Sentinel removed, plug in the replaceable battery
pack into the orange two-pin connector.
2) Locate the little white button which is mounted to the right of the orange two-pin
battery connector.
3) Verify the Sentinel’s antenna is pointing straight up.
4) Press and hold the little white button until a green LED lights up.
5) The green LED will flash fast (half second ON, half second OFF).
6) Upon establishing the link, the green LED will flash slow (one second ON, one
second OFF).
7) When ready to transmit, the green LED will go to solid ON for about 10 seconds.
This is the actual transmission of data to the Base Station.
8) After a successful transmission, the green LED will extinguish. The Sentinel is now
in passive mode, and will remain in passive mode until the next scheduled
transmission time (determined by Jumpers J2 & J4 – Number of Callouts per Day), or
when the little white button is pressed and held again.
9) If the data transmission was not successful, a red LED will flash once, followed by
up to ten green LED flashes. The number of green LED flashes following the red
LED flash corresponds to an error code. Refer to Section 7-1 of this manual for
information on the error code.
10) Note the time the LED went to solid ON (the actual data transmission). Contact the
SupplyNet Monitoring Center at 888-826-5546, ext. 713 to verify a successful data
transmission from the Base Station, and to verify tank information.
11) Replace the black cover onto the Sentinel finger tight.

Remote Tank Unit ID
Each Sentinel has a unique embedded RTUID number. This number is printed on the
label found on the outside of the body of the Sentinel. For proper communication this
number must match the RTUID setting for the tank that is setup in the Base Station.
Failure to do this will result in an error message displayed on the Base Station. This
message is as follows: “MESSAGE FROM UNKNOWN RUTID”.
3-4
Setting the Number of Callouts per Day
The Sentinel can be jumper set to transmit the current data once every 8 hours, or once
every 24 hours. The first callout is set when the white button is pressed for a forced
transmission.
For instance:
The white button is pressed during commissioning at 9:00 am. For a transmission every
24 hours, an automatic reading will be transmitted every day at 9:00 am. For a
transmission every 8 hours, the reading will be transmitted at 9:00 am, 5:00 pm, and 1:00
am.
CAUTION:
If you set the number of calls to a number greater than the number of calls included in
your service agreement, then an additional fee will be charged for each call above
your allotment.
Jumpers J2 and J4 within the Sentinel control the number of callouts. The table below

Determining the Signal Strength
During installation, the strength of the signal from the Base Station should be determined
using the LEDs on the transmitter board in the Sentinel. Pressing the start button and
holding it for two seconds, look for the green light to begin flashing at the top of the
main board. In approximately 30 seconds the transmitter power will come on as indicated
by the red light at the bottom of the radio board. At the same time the row of lights in the
middle of the board will flash in sequence indicating a proper start up of the radio. The
end light flashes continuously and is normal. The light at the other end of the row is the

Tank Measurements
Accurate tank measurements are required to properly complete the installation process.
The Sentinel can easily determine the product level, however, accurate tank dimensions
are required to convert a measured product level into a calculated product volume.
Figure 7 illustrates tank terminology used for the calculation of the capacity of the tank.
Tank capacity is typically the tank volume up to the “Top Tangent Line”. Any dome or
dish on the top of the tank is not included in the capacity determination.
The orientation of the tank below the “Bottom Tangent Line” can greatly affect the
product volume calculation. The distance below the bottom tangent line is measured by
first measuring the distance from the bottom tangent line to the ground, then subtracting
the distance from the ground to the absolute bottom of the tank.
Some tanks have a small cube “Box” at the very bottom of the tank, typically at the
bottom of a cone. This box can be easily measured and depending on the size of the box,
can affect product volume calculation.

Mounting the Unit (Pressure Differential)
Pressure Differential Sentinels operate by measuring the pressure (weight) of the liquid
the sensor is submerged into.
The opening on the end of the sensor contains an exposed diaphragm which responds to
changes in liquid pressure as the tank is filled or emptied with product. This measured
pressure is compared against atmospheric pressure, and is converted to a readable signal
by a microprocessor in the Sentinel.
Please note that the sensor and sensor cable must be clean when installed, to avoid
contamination of the contents of the tank. These tanks are inspected for product
contamination, and the Sentinel installation cannot compromise the product in the tank.
Care must be taken before and during installation to not strike the sensor against any
stationary surface. This can frequently occur during installation of the probe into the
tank. Shock may damage the probe causing it to fail prematurely.
Ensure the probe can reach the bottom of the tank.
CAUTION:
Typically there will be more cable than what is required for the sensor to reach the
bottom of the tank. This “slack” cable must be taken care of during the installation.
The slack must be looped and secured using typically three plastic or non-metalic
ties, so the loop will not come apart. A correct installation will result in the sensor
just slightly resting at the bottom of the tank, with all excess slack secured in the
loop. There should not be enough excess cable for the sensor to enter into the
discharge piping. Refer to Figure 6.
Verify the sensor and cable slack loop can pass thru all plumbing without having to
disassemble the plumbing. Ensure the threads at the Sentinel mounting point have not
been compromised. The Differential Pressure Sentinel is now ready to be placed into
service.

Ultrasonic Sentinel Installations
“A” is NOT a good installation, since the bung opening is less than 1/3 the tank diameter
away from the edge of the tank. In this example, a Differential Pressure Sentinel will
have to be used instead of the Ultrasonic Sentinel.
“B” is a GOOD installation. The bottom of the Sentinel is into the tank, and the Sentinel
is mounted plumb and close to the center of the tank.
“C” is NOT a good installation, since the Sentinel cannot be mounted plumb. In this type
of installation, the ultrasonic signal will not bounce directly from the product back to the
sensor, but will instead bounce around the inside of the tank, causing inaccurate or even
no reading. In this example, a Differential Pressure Sentinel will have to be used instead
of the Ultrasonic Sentinel.
Note:
For installation geometry other than those shown, contact SupplyNet
Communications. An Extended Length Ultrasonic sensor may be an
alternative option.
Once the bung opening is verified to be a good Ultrasonic installation, ensure the bung
threads have not been compromised. The Ultrasonic Sentinel is now ready to be placed
into service.

Mounting the Unit (Ultrasonic)
Ultrasonic Sentinels operate using sound wave technology, which pulses sound waves
from the bottom of the Sentinel downward into the tank. A microprocessor times how
long the sound wave takes to bounce off the liquid level in the tank and return to the
Sentinel.
The transmitting and receiving of the sound waves take place from the bottom of the
Sentinel. Therefore, the location of the Sentinel bottom in relation to the opening of the
tank is critical.
CAUTION:
The bung opening must be plumb in reference to the overall tank.
The distance from the top of the bung opening to the inside surface of the tank can be
no greater than 1.0 inch. Refer to Figure 4.
The bung opening must be at least 1/3 the overall tank diameter away from the tank
edge. For example, if the tank diameter is 90 inches, the bung opening must be at
least 30 inches from the tank edge. Refer to dimension 1 of Figure 5.
The distance from the top of the bung opening to the very bottom of the tank can be

Poly Tank Preparation
Please check the following before installation of the Sentinel:
• A 2 inch diameter threaded opening is required for the installation of a Sentinel. If the
tank does not have a threaded opening available, a hole must be cut into the top of the
tank. Refer to the procedure below for the installing a plastic bung kit.
• For Differential Pressure Sentinel installations, verify if a mechanical agitation device
exists within the tank, which could damage the sensor.
• For Ultrasonic Sentinel installations, verify no obstructions exist within the tank which
could alter the ultrasonic readings.
Installing a Plastic Bung Kit
The following tools are required to complete this procedure:
Plastic bag for catching debris
Duct tape
Drill with a 3-inch holesaw bit
2 inch Plastic Bung Kit
1) Open the manway at the top of the tank.
2) Open the plastic bag and secure the opening to the approximate center where the hole
will be drilled. The bag will catch any debris created by the holesaw while drilling
the bunghole.
3) Using the drill and 3-inch holesaw bit, drill thru the plastic tank.
4) Once the hole is cut, remove the garbage bag. Use care in removing the bag and duct
tape off the inside surface of the tank.
5) The 2 inch Plastic Bung Kit may now be installed. The Bung need only be tightened
by hand. Refer to Figure 3 for proper assembly.

Stainless Steel Tank Preparation
Please check the following before installation of the Sentinel:
• A 2-inch diameter threaded opening is required for the installation of a Sentinel.
Stainless Steel tanks are typically built with one or more 2-inch threaded “bung”
opening. The tank’s vent line can be modified to provide both tank venting and access
for the Sentinel, if the vent is the only 2-inch threaded opening available. Refer to the
procedure below for the installation into a vent line.
• For Differential Pressure Sentinel installations, verify if a mechanical agitation device
exists within the tank, which could damage the sensor.
• For Ultrasonic Sentinel installations, verify no obstructions exist within the tank which
could alter the ultrasonic readings.
Installation into a Vent Line
Note:
The following procedure can only be used with a Pressure Differential
Sentinel. Ultrasonic Sentinel’s must be installed directly into a bung opening.
The following tools are required to complete this procedure:
Two Pipe Wrenches
2-inch Vent Kit consisting of either non-metallic or Stainless Steel material
• one 2-inch Tee
• one 2-inch 90 Elbow
• two 2-inch Close Nipple
1) Using the two pipe
wrenches, remove the
existing vent assembly
from the top of the tank.
2) Assemble the Vent Kit
items in the manner
shown in Figure 2.
3) Install the existing vent
assembly onto the 90
Elbow as shown in Figure
2.
4) Install the Differential
Pressure Sentinel onto the
top of the Tee as shown
in Figure 2.

Safety Precautions
The Sentinel™ uses Radio Frequency (RF) waves for communication to the nearest Base
Station. In general, the Sentinel should be able to communicate properly if you are within
1000 feet of the Base Station. However, because of the inherent characteristics of RF
communications, there are certain guidelines that should be followed when positioning
the unit.
Warning !
•
•
•
•
Do not use the Sentinel™ in hospitals or near medical equipment.
Do not install the Sentinel™ where hazardous vapors are present.
Do not use the Sentinel™ where blasting is in progress.
Electrostatic discharge can damage sensitive electronic components. Be sure to touch
a grounded object before working on the internal circuit board.
The unit should be located in an area free from overhanging metal structures, large
obstructions, or equipment which could generate RF or electrical interference.
If you have doubt about the suitability of a particular location for the Sentinel™, or
are having difficulty transmitting, please see Sections 3-2 and 3-3. Please contact a
SupplyNet Communications specialist to determine your exact needs.

Initial Inspection
When you receive the Sentinel™ unit, thoroughly inspect it for any damage which may
have occurred during shipping. If there is any damage to the Sentinel™, contact the
shipping company as soon as possible. Locate the packing checklist in the shipping
container. Check for any missing items before you begin installation of the Sentinel™.
Note: The Sentinel™ is shipped with the antenna disconnected. It is located in a
separate compartment within the shipping carton. Verify that the antenna is
present before proceeding.

The Sentinel™ communicates to the Base Station using a short range radio. The distance
is limited to 1000 feet. The Base Station is capable of receiving data from multiple
Sentinels forming a Local Area Network (LAN) configuration. The maximum number of
Sentinels communicating with the Base Station is 24. The Base Station in turn
communicates directly with the TankLink® data center using a wireless cellular
technology called Microburst®. This patented technology allows the unit to transmit
digital data to the TankLink® data center using the existing network of analog cellular
towers deployed throughout North America. Every area with analog cellular service has
two carriers, an ‘A’ carrier and a ‘B’ carrier. In order to transmit a Microburst® data
packet, the local cellular carrier must be Microburst® enabled. Fortunately, nearly all
areas in the United States have at least one Microburst® enabled carrier. Many regions
have two Microburst® carriers. In these areas, the installing technician can choose which
carrier to use based on the proximity of the unit to each carrier’s cellular towers. There is
no difference in cost using one carrier over the other, unlike cellular telephone rate plans
from competing companies. Once the data is at the TankLink® data center, it may be
viewed over the internet using a standard web browser (ie. Microsoft Internet Explorer or
Netscape Navigator), downloaded to applications such as Microsoft Excel, or it may be
used to trigger events such as an e-mail or page to a local sales or service representative.
To access the data provided by the Sentinel™ unit, a current monitoring service
agreement with SupplyNet Communications is required. For help with accessing the
TankLink® web site, see Chapter 5. Since the Sentinel™ is a wireless device, care must
be taken when installing the unit to minimize interference from nearby equipment or
structures. For installation guidelines, please refer to Chapter 2.
