How Does a Fuel Level Sensor Work?

Sensors are a crucial part of most vehicles, especially when determining the fuel level in automobiles and aircraft. Whilst running out of fuel might be inconvenient and costly when driving an automobile, in an aircraft it could have dire consequences. In this article, we look at how these fuel level sensors work. Fuel Level Sensors, also known as fuel gauges, allow drivers to monitor fuel consumption and help them to determine when to refill the tank. They consist of two main components: the sensing system itself (also known as the sender) and the indicator (also commonly referred to as the gauge).


Capacitive Fuel Level Sensors work by measuring the voltage across a variable resistor within the sensing system, to determine the level of fuel; which is then relayed to the driver via the indicating system. Several components work within the sensing system, enabling it to detect how much fuel is in a tank, including the float switch, a variable resistor, and a wiper. The sensor system is relatively simple compared to other sensors currently produced, although newer sensor systems can also utilize microprocessors for faster and more accurate measurements.






Global Positioning System (GPS) is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. The Global Positioning System is mainly funded and controlled by the U.S Department of Defense (DOD). The system was initially designed for the operation of the U.S. military. But today, there are also many civil users of GPS across the whole world. Civil users are allowed to use the Standard Positioning Service without any kind of charge or restrictions.


Global Positioning System tracking is a method of working out exactly where something is. A GPS tracking system, for example, may be placed in a vehicle, on a cell phone, or on special GPS devices, which can either be a fixed or portable unit. GPS Tracker works by providing information on the exact location. It can also track the movement of a vehicle or person. So, for example, a GPS Tracking Software can be used by a company to monitor the route and progress of a delivery truck, and by parents to check on the location of their child, or even to monitor high-valued assets in transit.


A GPS tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS Vehicle Tracker devices to give information on location, vehicle speed, time, and direction. So, a GPS tracking system can potentially give both real-time and historic navigation data on any kind of journey.






Driver monitoring systems (DMS) are making a pivotal contribution to road safety, both in commercial truck fleets and passenger cars. These systems use a driver-facing camera to evaluate the driver’s state of alertness. If it detects fatigue or distraction, Driver Fatigue Monitor sends a warning or alert. In partially automated vehicles, the system notifies the driver when a vehicle-initiated handover is required.


It is now well accepted that camera-based DMS is the most appropriate way to directly track driver drowsiness and distraction and perform safe, vehicle-initiated handover in semi-autonomous cars, concluded ABI Research analysts in a recent study of driver and in-cabin monitoring systems.


The DMS segment is poised for significant growth thanks in part to the support of leading safety agencies. In February 2020, the National Transportation Safety Board (NTSB) in the US recommended the use of DMS as an effective means of driver engagement in SAE Level 2 vehicles. Euro NCAP recognized the importance of DMS in its revised crash-test safety standards, which starting this year require DMS for a five-star rating. By 2022, DMS will become mandatory across the European Union for M1, M2, M3, N1, N2, and N3 new vehicle categories.






Fleet Management Sensor has been radically transformed by innovations such as smart devices and sensors in the digital age. The IoT-enabled future of the supply chain industry looks promising as more companies across the globe are embracing the technology.


Research predicts the revenue of the global IoT fleet management market will reach an estimated US$15,500 million by 2024. This is not surprising at all because the sector has achieved great strides by being tech-forward.






The acronym stands for Mobile Digital Video Recorder and is responsible for all business intelligence behind the video monitoring, such as storing videos, settings, remote functions, etc. Without it, cameras are simply cameras. The MDVR is capable of recording your images in high resolution, storing the files internally and sending them to the cloud, when connected via Wi-Fi, 4G and Ethernet (the conventional internet cable). However, in the event of an accident, the MDVR can be used to retrieve the information, which is stored on SSD for approximately 10 days.
