KUM2500C Ultrasonic Fuel Tank Level Sensor 0.1mm Measurement
Resolution
1. Production Overview
The KUM2500C ultrasonic fuel tank level sensor is an advanced and
highly precise device engineered for fuel tank level measurement.
With an astonishing 0.1mm measurement resolution, it offers an
unprecedented level of accuracy.
This sensor is designed to meet the demanding requirements of fuel
monitoring in various applications. Whether in automotive,
industrial machinery, or large - scale storage tanks, it performs
excellently. The ultrasonic technology employed by the KUM2500C
enables it to send out high - frequency sound waves that precisely
measure the distance from the sensor to the fuel surface. Its
design ensures reliable operation even in harsh and complex
environments within the fuel tank. The high - resolution
measurement capability allows for extremely fine - grained data,
enabling users to have a detailed understanding of the fuel level
at all times. This not only helps in efficient fuel management but
also in preventing issues such as over - filling or running out of
fuel unexpectedly.

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.
