It is a perfect solution for monitoring the fuel level and fuel consumption of commercial vehicles and also stationary tanks, etc. The sensor can detect and report fuel theft in real-time by sending an alert. For the fuel level, it is measured and sent to GPS tracker directly, then upload it to the server and processed to display on your computer, mobile phone or tablet.

Important notes:
● Because the couplant and grease are forbidden materials for air transport, so you need to buy these two materials from local shops before the installation.
● Do not wash the tank within 6 hours after installation.
● Do not install the sensor when the temperature is below minus 10 degrees.
Installation Flow Chart:
Step 1: Check the current fuel level:
Please check the fuel gauge or fuel tank directly if the balance fuel level is around or over 50%, it is important for locating the installation spot and testing the sensor after installation.
Step 2: Find and clear the installation area:
The sensor must be installed on the central area of the bottom of the fuel tank as per above figure. Please clear this area completely before installation.
Important Note:
The mounting position is critical for ultrasonic level sensor. So please ensure that above this installation area is away from fuel filler, oil gauge, internal partition, otherwise the ultrasonic wave may not reach the top of the fuel and get back with correct data.
Step 3: Connect the sensor to digital indicator
● Connect the sensor to the digital indicator.
● Connect the digital indicator to vehicle power supply directly.
Step 4: Check & Locate the installation spot
● Put the couplant on the surface of the senor (the side without the label).
● Stick the sensor on the center of the installation area and hold it, check the results from digital indicator according to the following instruction table.
● If the result is ok, mark a round installation spot on the fuel tank.
Digital Indicator Instruction:
Installation requirements:
For iron tank, at least 1 echo and the installation status code should be 1 or 2.
For aluminum or stainless-steel tank:
• when the height of the fuel is < 60cm, it needs at least 2 echoes and the installation status code should be 2;
• when the height is > 60cm, it requires at least 1 echo and the installation status code should be 1 or 2.
Step 5: Install the sensor
Firstly, please clear the testing couplant on the surface of installation spot and probe completely.
5.1 Install the protective holder
Please make sure the center of the holder matches the marked round installation spot, also the holder should be parallel to the vehicle frame (chassis)
5.2 Install the Model TUB sensor
a. Put the ring gasket on the surface of the sensor, then fill the measuring area with grease, make it a bit higher than the ring gasket. There must be no air bubbles or dust or sand inside the grease.
b. Insert the sensor into the holder and install the cover plate.
c. Connect to the digital indicator and check if the results are ok.
5.3 Fasten the holder
a. Fasten the holder with the stainless-steel clamp tightly and put the rubber pad on four corners of the fuel tank below the clamp.
b. Fasten the joint of the steel clamp with a cable tie.
Step 6: Connect the sensor to GPS tracker
● Remove the digital indicator.
● Connect the sensor to the extension cable, wrap the connection with insulating tape.
● Connect the fuse wire to the red wire of the extension cable.
● Fasten the extension cable to the chassis with cable ties and then connect to GPS device.
We suggest to wrap the joint of extension cable with black insulating tape and tie the cables as the following example, to reinforce the connection.
