- Page 2 Android application. Invasive installation TEK 880 device has a 2” BSP threaded opening to allow it to be screwed into an existing 2” opening of a tank. An O-ring is supplied and should be used to ensure a watertight seal.
- Page 3 TEK 880 Radar LTE User Manual It is important to ensure that water or any other substance does not ingress inside the cavity formed by the adapter and the sensor enclosure. The location of the non-invasive mounting should be carefully chosen to avoid internal obstacles and other obstructions that would interfere with the radar signal reaching the internal contents of the tank.
- Page 4 TEK 880 Radar LTE User Manual Sensor mounting The mounting position of the TEK 880 device is important for best results. The sensor should be mounted horizontally with a direct view of the liquid inside the tank without any obstructions. It should also not be mounted too close to the edge or near metallic objects.
- Page 5 A magnet is supplied with the device to activate and start cell module communications with the internal Bluetooth communication module (BLE) module. The magnet is held over the Tekelek Logo ‘hotspot’ for approximately 2 seconds until a double-beep repeating approximately every second is heard from the internal beeper.
- Page 6 Then select the TEK 880 sensor that you wish to connect to ( highlighted in yellow below). Note - the TEK 880 sensor high tone (double) beeping will cease to indicate that the cell phone and TEK 880 are connected.
- Page 7 TEK 880 Radar LTE User Manual The Tekelek BLE app should connect to the TEK 880 sensor and display a screen similar to below (A green header indicates an active connection). This is the main display for the communication between the Tekelek phone app and the TEK 880 Radar unit and shows the interactions between the two devices.
- Page 8 The installation sequence is as follows: a) The tank height by default is 100cm. This is the height from the base of the TEK 880 sensor to the base of the tank or outlet height. If the tank on which the TEK 880 sensor is to be installed has a different height, then this needs to be correctly set before moving on to the next steps.
- Page 9 TEK 880 Radar LTE User Manual b) Select the correct liquid type and setup to be measured. The sensor uses a series of internal settings /coefficients that optimise its performance for different liquid types. In the example shown below the installer can select “Hydrocarbon - Oil Setup” from the command list to indicate to the sensor that these internal coefficients should be used.
- Page 10 TEK 880 Radar LTE User Manual A series of messages will appear on the terminal indicating the progress. The module responds with multiple … The sensor will register to the network. It should then send its data to the server.
- Page 11 TEK 880 Radar LTE User Manual The “Data Rx” received, indicates that the server has received the message and replied with a RTC (real time clock) update to synchronise the sensor to the network time. If there are problems at this stage, then the network strength may need to be checked to ensure that there is an adequate signal available.
- Page 12 Once this command is complete, then the unit is installed and is correctly communicating with the server and will return to sleep until the next scheduled dial-in. An example below shows the Tekelek server reporting the ullages received from a sensor over a period of a month.
- Page 13 For installation cases where the sequence of events as previously described does not occur. Some debugging support may be required. The root cause may be server, connectivity or other issues. To expediate support it can be useful to send the screen logs to Tekelek support for further assistance.
- Page 14 TEK 880 Radar LTE User Manual APPENDIX: 1. Signal diversion of the radar unit – typically 8 … 10◦. 2. The radar mounting position should be positioned to avoid internal obstacles or adjacent to metal parts of tank supports. 3. For metal tanks – setting the tank height is important to avoid picking up reflections off the tank bottom or objects beneath the tank.

Refer to the 9-6251 User guide. 6. There are other methods to fix the TEK 880 sensor to the tank. These include strapping or screwing into position on top of tank. The example below shows a TEK 880 Radar sensor mounted onto a cage around a plastic tank.
