1 Introduction
Ultrasonic fuel sensor uses ultrasound technology to monitor the level height of fuel or liquid without tampering the
tanker. It is widely used to connect with GPS tracking device to realize real time fuel consumption monitoring or fuel
amount monitoring during transportation.

8mm.
⚫ Built-in interference proof algorithm, smart and efficient
1.4 Application
⚫ Fuel consumption remote monitoring for any type of vehicle, truck or car
⚫ Dangerous liquid transpiration monitoring
⚫ Construction vehicle fuel usage monitoring
⚫ Water truck monitoring
⚫ Storage tanker monitoring
1.5 Package
1x ultrasonic fuel sensor
1x 8-meter extension cable
1x installation bracket with screws
1x abrasive paper
5x plastic ribbon for wire fixing
1x display for liquid height display (optional)
2 Before Installation
Please make sure take display and power bank for sensor installation.
2.1 Display Usage
Display is connected with sensor head and powered by power bank so as to show current tanker fuel height. If the
displayed height is same as current fuel amount height, it means the current installation spot is right.
2.2 Before installation
⚫ Park vehicle on flat road
⚫ The height of current fuel amount in tank should be higher than 6cm, for construction vehicle or boat, the height
must be higher than 12cm
⚫ The installation spot is advised to be at the middle bottom of tank.
⚫ The installation spot must be smooth, clean and clear.

3 Installation
3.1 Locate installation spot
Couplant is in the circle area
Put some couplant in the middle of sensor head
3.2 Sensor installation
3.3 Bracket installation
3.4 Paste waterproof glue
1.area among sensor and bracket, paste waterproof glue
2 area out side of the bracket, paste AB glue to strength bracket
3 Display is always connected during the installation.
4 Power sensor and connect device
1 Sensor Black for GND, Red for Power.
2 Yellow: 0-5V is to connect with GPS speed limiter UT04s Grey wire.
Check if height display is right,
otherwise make sure the tank is
smooth, clean and clear.
1. Remove couplant
2. Paste butter in the circle
1. press sensor head to installation spot
2. No more movement once okay
If failed, turn the head till fuel
amount height displays right
Or change a place
1.mix A and B glue at
proportion of 1:1
2.glue should be out
side of red circle area
1.Place bracket as picture
2.Wait for glue to solidify around 6
mins to 10 mins.
3.Tighten the bracket screws properly
