KUM2500C Ultrasonic Fuel Tank Level Sensor 0.1mm Measurement Resolution

KUM2500C Ultrasonic Wave Oil Level Sensor

1. Production Overview
Ultrasonic oil level sensor is the oil quantity monitoring equipment designed for management personnel of enterprise motorcade. It can prevent gasoline theft by drivers, optimize transportation cost, the driver’s driving action and assist statistical decision, etc. The sensor uses ultrasonic probe to detect the oil level height and carries out smart processing for height signal of oil quantity through built-in program of the main body. Then it sends the oil quantity information to the system platform through GPS to generate the oil quantity report after analysis. The sensor supports serial port and analog output and can connect with GPS of most brands/Beidou all-in-one machine. Therefore, the sensor can be connected with the backstage monitoring system easily.
The products adopt non-contact measurement ultrasonic wave sensor technology developed independently by our company and first created domestically and are widely used in fuel consumption monitoring projects for vehicles and sold overseas.

3.4 Product characteristics
1. High precision: The resolution ratio of oil level height measurement of the oil level sensor is 0.1mm and the measurement accuracy is ±0.5%. High measurement accuracy can be guaranteed at high temperature and high cold external environment.
2. Good long-term stability: The oil level sensor adopts ultrasonic wave measurement method and performs non contact measurement. It is different from the float-type, pressure type, magnetic sliding system measurement methods that adopt direct contact measurement methods at present generally so as to avoid corrosion and pollution of oil level sensor by fuel oil and maintain long-term stability.
3. Easy installation and maintenance: It only needs to install the sensor probe at the lower part of external fuel tank. There is no need to change the existing measurement system of the fuel tank, no need to drill hole and make change on the fuel tank. At the same time, it can guarantee normal operation of former oil meter of vehicles.
4. Environmental sound, small energy consumption. Non contact measurement makes it unnecessary to bore hole on or modify the fuel tank. No dirt and pollution will be brought to the fuel oil.
5. Strong reliability: Still work normally at hostile environment; anti-damp, anti-acid, inflaming retarding, anti-interference and Intelligent.
The product can be used independently by using the auxiliary display screen. It may also be used with GPS equipment by transferring the data to backstage through GPS equipment for data statistics, statement analysis and query.
2.5. Applicable scope
The ultrasonic oil level sensor is geared to all types of vehicles (such as logistics vehicles, taxi, buses and passenger cars, etc) to record the refueling, oil consumption of vehicles with digitalization to prevent occurrence of fuel theft, avoid resources waste, improve management efficiency and traffic safety and enhance operation management level.

4.Wiring
1. Arrange the extension line into the cab. Wiring should follow the crossbeam of the vehicle at the time of wiring. It should not affect the original self unloading hopper, head repair, etc and other original functions.
2. The extension line should be away from the vehicle’s motor to avoid producing electromagnetic interference produced by the motor.
3. The terminal of the probe line and extension line should be convolved properly to prevent falling off.
4. The extension line should be at least 20cm distance to the heating parts of the vehicle. Fixing ribbon is used to fix the extension line every 50cm. Arrange the wire at the installation position of the vehicle reasonably.
 

5. Connect the vehicles and confirm platform data
1. Disconnect with the power supply and fix the main body at the position close to GPS (where water leakage will not occur) and fix it properly;
2. The red and black wire of user interface line is connected to the public power supply of the vehicle with red wire connecting the positive role and black wire connecting the negative pole.
Select the interface mode according to collection oil consumption interface of GPS.
A. analog quantity: The green line is connected with GPS collection analog port. The black wire is connected with GPS collection analog ground;
B. RS232 Communication: The yellow wire (TX) is connected with GPS RX and the blue wire (RX) is connected with GPS TX. The black wire (GND) is connected with GPS ground.
C. RS485 Communication: The brown wire (B) is connected with B of GPS; the purple wire (A) is connected with A of GPS and the white wire is connected with GPS ground.
3. Power on and check whether the platform provides oil consumption data.
