Normally there are 2 types of Fuel sensor is popular in the market, it is ultrasonic fuel sensor, Probe fuel sensor, details as below:

- Avoid sensor corrosion and contamination of fuel, and maintain long-term measurement stability.

(2) Probe fuel sensor
Advantages:
- Cost is lower compare to ultrasonic fuel sensor
- Convenience: It can be fixed by flange or thread, which is easy to operate.
- Independence: The fuel consumption value is obtained directly by measuring the oil volume of the fuel tank, and does not have any effect or influence on the oil system/pipe.
- Uniqueness: With range self-cutting function, the user can recalibrate by pressing the button, and the digital output can also be equipped with debugging software.
- Self-adjusting: The sensor can adjust and install the range according to different tank sizes. The sensor adds temperature compensation function to automatically correct the error caused by the change of fuel volume caused by temperature change.
- Safety: Directly replace the original vehicle fuel gauge, no need to re-install the capacitor sensor on the fuel tank. The electronic cabin is explosion-proof and certified by Exia IIBT6 Ga. The sensor flange has two layers of leak-proof slots to prevent oil leakage.
- Stability: Without any mechanical moving parts, mature and stable circuit structure and high-quality components will make the sensor continuously used for several years without replacement.
