Ultrasonic Fuel Level Sensor / Clamp On Fuel Oil Tank 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.

Note: The baud rate and interval of data transmission can be
2.3 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
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
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.
2.4 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.
