With the modern fuel crisis and prices rising, it is vital that fuel level data is accurate and provided in real-time. Modern vehicles have a fuel level sensor located within the fuel tank.
This sensor is a lever that hooks up to a voltage measuring system. As the fuel level rises or falls, the lever moves up and down, altering the resistance in the circuit. This resistance can be converted as a signal to indicate to drivers how much fuel is left in the tank using fuel level data from the ECU.
Data from fuel level sensors are used to work out the estimated range of a vehicle. If the fuel level is known, combining this with current and historic consumption data can give an estimated reading on a vehicle’s remaining range.
Fleet management can remotely access vehicle fuel level data. This in turn can assist drivers by offering advice on when they should next fill up. Finding cheaper fuel stations is important in today's high priced market. With fuel level data, fleet operators can work out where a driver will be when they are running low and can even pre-plan stops at the cheapest fuel stations.
Fuel level data can be used for cost calculations for running the vehicle. As the range of a fuel tank is important when planning journeys, refuelling and optimising a fleet operation. This data can detect any illegal siphoning from the vehicle too. Combining this with location data, it can calculate where the siphoning took place for evidence to local authorities.
Fuel quality can be compared across different fuel stations. If a poor quality fuel offers worse consumption, fuel level data can detect this.
