Digi Connect® Tank v2 User Guide
Digi Connect Tank v2 allows you to remotely monitor the liquid level in a single tank. The Connect
Tank device operates wirelessly by running on a long-life battery and communicating through the
cellular network.
Note Do not use Connect Tank to measure levels of non-liquid tanks. The Connect Tank device uses
ultrasonic sensing, which requires a uniform surface to take accurate measurements. Solid material
does not provide a uniform surface.
Using its ultrasonic sensor, the Connect Tank device transmits a narrow ultrasonic sound beam to the
surface of the liquid and reflects back to the sensor, as shown in the following figure. The device
measures the amount of time it takes for the ultrasonic sound beam to travel down to the surface of
the liquid and reflect back to the sensor. The device then converts the amount of time into a
measurement showing how far the liquid is from the top of the tank in inches and reports that
information to your Digi Remote Manager account.

Get started
Before installing the Connect Tank device in a tank, make sure you review the information in this
section and complete all of the tasks.
Verify product components
Make sure you have the necessary parts in the box.
Connect Tank includes the following components:
Connect Tank Battery Gasket lubricant
The following accessories are available through Digi International Inc. For more information, see the
Digi Connect Tank product support page.
Activated SIMcard
(when you purchase Digi
Bundled Services)
Assemble the device
Before you begin, make sure you have the following required equipment to assemble the Connect
Tank device:
n One 9/64-inch or 3.5 mm hex key
n Activated SIMcard: See Activate a SIMcard
Digi Connect® Tank v2 User Guide
NPT adapter
(for some tank configurations)
Magnet
(for manually waking the device)

Get started Assemble the device
CAUTION! This product contains a lithium metal battery. Prior to installation, the
battery should be inspected for any signs of damage. If the battery appears to be
damaged or is dropped during the installation, do not use the battery and dispose of it
properly. See Battery inspection for more information.
To assemble the device:
1. Use a 9/64-inch or 3.5 mm hex key to loosen the four retaining screws and open the Connect
Tank enclosure cover.
Digi Connect® Tank v2 User Guide

Get started Assemble the device
2. Insert the activated SIM card.
a. Orient Connect Tank to match the picture below.
b. Unlock the SIM card tray by gently pushing the metal bar toward the bottom of the
tray.
c. Open the SIMcard tray by pulling the tray up from the top or right side of the tray.
CAUTION! Do not pull the SIMcard tray up from the left side or use a
tool to open the tray. These actions may damage the SIM detect
switch, which is beneath the left side of the tray.
d. Insert the SIM card into the SIMcard tray, with the metal contacts face-down and
the flat edge inserted into the holder.
e. Press the SIMcard tray onto the board.
f. Lock the SIM card tray by gently pushing the metal bar toward the top of the
SIMcard holder.

Get started Assemble the device
3. Place the battery in the battery holder. Make sure that the wiring attached to the top of the
battery is NOTplaced in the battery holder, as shown below.
4. Connect the wiring to the battery port on the circuit board.
5. (Optional) If your tank has a 2-inch NPT threaded opening, you can attach a 1-inch to 2-inch
adapter to the bottom of the device.
Note If you are using a 2-inch NPT adapter, you should only use the adapter available through
Digi International (part number 76000910). This adapter has been modified specifically to not
cause reflections of the ultrasonic signal. Standard 2-inch NPT adapters will interfere with the
ultrasonic signal and cause incorrect tank level readings.
6. If this is the first time you are assembling the device, complete initial configuration using the
CLI. For more information, see Initial Connect Tank configuration. If initial configuration has
been completed, you can skip this step.

7. Reassemble the device.
a. Place the enclosure cover onto the base. To ensure that a gap does not appear
between the cover and the base:
n The green dots on the cover and the base must both be on the same side of
the device, as shown below.
n Make sure that the battery holder in the cover aligns with the battery holder
in the base.
b. Verify that an adequate seal is present between the cover and the base.
c. Tighten the screws
CAUTION! Cover screws are required as part of the safety rating. When tightening the
cover screws, use a screw torque of 0.79 to 1.92 newton meters (7 to 17 inch pounds).
Activate a SIMcard
You can activate a SIMcard from your cellular provider or from Digi.
1. Your SIM card provider needs the following information:
n Connect Tank IMEI number: The IMEInumber is on the label on the Connect Tank
device and on the box the device was shipped in.
n SIM card number: The SIMnumber is printed on the SIMcard.
2. Call your SIMcard provider to activate the SIMcard.
LED indicators
The Connect Tank device has two LED indicators to monitor the battery function, and the cellular
network connection, and GPS locating.
