Fuel Sensor is used to measure and monitor the fuel level and Fuel consumption of Trucks, Fuel Tankers, Boats, construction equipment, Generators, Stationary tanks, etc..
What is an ultrasonic fuel level sensor?
The ultrasonic fuel level sensor is a non-invasive device that does not require contact with the fuel and measures the fuel level in truck fuel tanks or generators. It is easy to install and environmentally friendly compared to other external fuel tank level sensor that needs to drill a hole on the tank before installation.
How does an ultrasonic level sensor work?
The ultrasonic level sensor measures fuel level using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected from the monitoring target.
The distance can be calculated with the following formula: Distance L= 1/2 x T x C
Where L is the distance, Tis the time between the emission and reception, and C is the sonic speed. (The value is multiplied by 1/2 because T is the time for the go-and-return distance.)
How is accuracy?
Ultrasonic technology is a very common liquid level sensor whose accuracy depends on the current reading. Ultrasonic sensors use sound waves to detect the liquid level, including fuel , diesel, and water. These liquid level sensors can have a resolution as high as 0.1 mm and an accuracy of 0.1% of the detected range in theory. With software data calibration, the fuel amount left in tank accuracy is above 98%.
Maximum range of the ultrasonic sensor
For ultrasonic sensing, the most widely used range is 40 to 70 kHz. The frequency determines range and resolution. The maximum range of our products is presently 20 meters. At 70 kHz, the measurement resolution is 0.1 mm and the range is up to 20 meters. The default sensor work range is 1 meter.
What should avoid with ultrasonic level sensors?
- Inappropriate application.
- Poor mounting angle.
- Chemical incompatibility.
- Choosing an ultrasonic level sensor with an adequate sensing range.
- Not using shielded cable.
- Improper cable routing.
- Poor quality power source.
Advantages an ultrasonic fuel sensor has
The sensor is connected directly to the vehicle battery, therefore it can detect and report a fuel theft in real-time by sending an alert even when the vehicle is switched off.
1. Affordable solution, high accuracy.
2. Simple installation, no need to drill or modify the fuel tank.
3. External mount measurement/non-invasive measurement.
4. No need to discharge fuel from the tank.
5. No calibration is required.
6. Suitable for all kinds of vehicles Fuel Tank, Generator Fuel Tank, Ship Fuel Tank.
7. No movable mechanical parts, maintenance-free.
Install an ultrasonic fuel sensor
The fuel tank level sensor has adhered externally to the bottom of the tank, which connects with an 8.0-meter cable to the GPS tracker 3 main steps are needed:
Step 1: Find a suitable installation position
Step 2: Install the sensor
Step 3: Power on and complete installation.
How does ultrasonic fuel sensor work with Sinocastel GPS Tracker?
Ultrasonic fuel sensor can connect with Sinocastel GPS tracker directly either by analog signal or RS232 or RS485 signal. After connection, sensor shall send reading value to GPS tracker, then GPS tracker sends the data to web tracking software. With proper algorithm and calibration on the software, detailed and accurate fuel left amount shall display on web and APP.
Solutions:
Fuel Sensor + IP67 waterproof 4G GNSS Tracker LT-168L 
Fuel Sensor + IP67 4G GNSS Tracker with big capacity battery T-235 
Fuel Sensor + 4G Telematics box with rich interface T-229 
Benefits of fuel level sensor + Sinocastel GPS tracker
Ultrasonic Fuel Tank Level Sensor works independent of the vehicle electronics, therefore it can detect and report a fuel theft in real-time by sending an alert even when the vehicle is switched off. On top of detecting fuel theft, it also allows real-time fuel monitoring and calculation of the remaining mileage based on the content of the tank.
Ultrasonic Fuel Tank Level Sensor measures and records the current oil level of the tank. Then the data is transmitted to the remote management platform through the 4G+GPS module. Users can check the real-time oil level and usage data through mobile phones or computers anytime and anywhere.
Conclusion
Ultrasonic fuel level sensor connects with Sinocastel GPS tracker is widely used for vehicle fuel consumption monitoring, optimizing operating cost, and monitoring driver behavior. Please feel free contact sales representative for more details.
