fuel level in a fuel storage device in a vehicle.

BACKGROUND OF THE DISCLOSURE
[002] The information in this section merely provides background information related
to the present disclosure and may not constitute prior art(s) for the present disclosure.
10 [003] Vehicles, but not limited to, such as two-wheelers or three-wheelers, or fourwheelers are equipped with a fuel storage tank. The primary function of the fuel storage
tank is to store the fuel to supply to an engine of the vehicle through a fuel supply
system. Most of the vehicles from the ancient era utilizes the force of gravity to supply
the fuel to a carburetor, which is fitted before the intake manifold of the engine. With
15 advancements in technology, the fuel storage tanks have been positioned at different
places based on the design of the vehicle and as per the safety norms. The distant
positioning of the fuel storage tank from the engine requires a fuel pump to facilitate
the supply of fuel from the fuel storage tank to the carburetor or engine. With the further
advancement in technology, the carburetors were replaced by electronic fuel injections
20 and mechanical fuel pumps were replaced by high-pressure electric pumps. The highpressure electric pumps comprise one or more motors that generate pressure to extract
the fuel from the fuel storage tank and forcibly supply the fuel to the engine of the
vehicle.
25 [004] Further, the in-tank fuel pumps have been used with mechanical fuel level
sensors, also known as fuel gauges. The mechanical fuel level sensors normally sense
the position of a float, floating on the fluid, by a mechanical linkage inside/outside the
tank. Various methods have been employed so far to measure fuel level, for example,
resistive film, discrete resistors, capacitive, ultrasonic, etc. Resistive-based sensors are
30 among the most commonly used. These sensors are mechanically connected to a float
which moves up or down depending on the fuel level. As the float moves, the resistance
of the sensor changes resulting in the position of the needle in an instrument cluster
changing proportionally to the current flowing in the coil. However, the resistive
3
contact-based sensors do not have long product life, since the sliding contact of the
elements inside the sensor facilitates wear and tear of the sensor.
[005] The vehicle manufacturers have tried and implemented different solutions to
5 limit the losses due to friction in said fuel level sensors. One such solution to subdue
these losses was to develop contactless fuel level sensors for the fuel pumps for
vehicles. The existing contactless fuel level sensors have minimum direct contact
between the moving elements of the fuel level sensors to reduce the losses from wear
and tear. The existing contactless fuel level sensors comprise a metallic float arm co10 molded with a magnet, thereby the magnetic flux generated by the movement of the
magnet is influenced by the metallic float arm which in turn provides variations in
results/outputs or provide non-linear outputs. Further, the process of manufacturing an
integral form of the metallic float arm with the magnet increases the cost of the fuel
level sensor. Furthermore, most of the elements of the existing contactless fuel level
15 sensors are not serviceable and result in the replacement of complete assembly even if
there is an issue in a single component. The non-serviceability of the contactless fuel
level sensors increases the maintenance cost of the fuel level sensors.
[006] The present disclosure is directed to overcome one or more limitations stated
20 above or any other limitations associated with the prior art.

with the movement of the floating member (8). In accordance with the movement of
the arm (6), the holding member (4) also moves. By the movement of the holding
member (4) the magnet housing (12) moves, thereby the magnet (14) gets displaced
12
from the axis X-X, which in turn varies the magnetic flux around the magnet (14). The
variation in magnetic flux is detected by the sensor (13) disposed in the sensor housing
(10) and, based on that, the sensor (13) generates signals and transmits the said signals
