Fuel Oil volume level sensor is based on the principle of radio frequency capacitance measurement and adopts a unique technology to realize automatic calibration.
What is a capacitive fuel oil level sensor?
Capacitive fuel oil level sensor also called Capacitive fuel oil level gauge is a part that detects the position (height) of the oil in the container by using the change of the capacitance between the sensor housing and the sensing electrode after the oil enters the container, and converts this change into a current change.
Fuel Oil Volume Level Sensor working principle
The sensing part of the capacitive oil level sensor is a coaxial container. When the oil enters the container, the capacitance between the sensor housing and the sensing electrode changes. This change is converted by the circuit and performs accurate linear and temperature compensation. , output 4-20mA standard signal supply display instrument. The outer metal tube of the sensor and the central probe constitute a coaxial capacitor. There is a gap between the two. The liquid to be measured enters this gap. Because the dielectric constant of the liquid and air is very different, the level of the liquid changes the capacitance of the capacitor. Capacity, the change of this electric capacity directly reflects the change of the liquid level. This change is processed by the circuit and the program, and the standard signal corresponding to the level of the liquid is output.

Capacitive fuel oil level sensor System advantages
Intelligent: The sensor calculates by itself, reports the fuel volume, fuel volume alarm, and fuel leak volume alarm, without platform processing;
Accuracy: The sensor collects hundreds of times per second, and the amount of data is large. The real data is filtered in real time at the first time, and the shaking during driving can be filtered out and repaired, and the calculated oil volume data is more accurate;
Cooperation: The vehicle-mounted terminal sends the real-time vehicle status (total mileage, ACC status, vehicle speed) to the sensor, and the sensor adjusts the algorithm and parameters according to the vehicle status to improve accuracy.
Timely: report the fuel filling amount and oil leakage in time, and report the oil leakage alarm within 15 seconds of the oil leakage;
Easy to use: platform calculus calculates the fuel tank fuel quantity array, and then sends the sensor; provides three calibration modes: real-time correction, real-time calibration, and retrospective correction;
Linkage: When the oil leaks, the sound and light alarm can be linked on the spot, and the remote oil leak process can be linked to video;
Variety: can detect single fuel tank, double fuel tank, three fuel tank, four fuel tank…
Sample report
Fuel quantity report: Fuel quantity statistics is a report module that counts the fuel quantity, mileage, speed, fuel temperature, ambient temperature, air conditioning and ACC status of the monitored objects connected to the fuel level sensor over a period of time
Refueling data: display all refueling data of the monitored object during the query time period
Oil spill data: display all the oil spill data of the monitored object during the query time period
How to installation a oil volume level sensor ?
Operating procedures
First: put the gasoline clean, then rinse it with water two to three times, and install it according to the following steps.
1. Positioning
The principle is generally in the middle of the fuel tank, avoiding the position of the original oil float.
2. Clean the dirt at the opening of the fuel tank
Remove the oil stains on the location where the fuel tank is to be installed
3. Drill through
Clamp a 50mm metal hole drill with a pistol drill, connect the power supply and drill in the middle of the positioned fuel tank, (note that the speed is not fast, stop when it is about to drill through, and peel off the metal to be drilled with a screwdriver and needle-nose pliers down to avoid it falling into the tank)
4. Clean up
Use a shrink file to remove the burrs from the opening
Use a magnet with a wire to put it in the fuel tank and suck out the iron chip.
5. Take out the sensor customized by the manufacturer according to the vehicle model
Remove the protective cover of the float and remove the 5 mounting screws and 5 self-tapping screws with a screwdriver.
Separate the sensor from the mounting flange.
Check flange O-rings. If it is complete, place it on the open hole.
6. Fixed
Use a pistol drill to clamp a 2mm drill bit, and drill holes in the 5 grooved holes of the mounting flange (to penetrate the fuel tank), put metal sealant on the 5 self-tapping screws respectively, and fasten the flange to the fuel tank. superior. Mount the sensor on the flange and tighten with 5 screws.
7. Seal
Use metal sealant to seal the flange and tank junction once.
8. Wiring
Connect the corresponding colored wires, and wrap the joints with black tape. Best line with casing. To run the line, go to the beam on the car.
