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).
Fuel gauges 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.
This digital sensor is fitted in to the tank of the vehicle/ gen set and it measures fuel level at any given time. Sensor is digital and capacitive type with its inbuilt software. Once fitted in to the tank, it is calibrated and calibration table is stored in its software. It will indicate amount of fuel filled/stolen/level with time, place and date. Its input is given to VTS and thereafter available on line for remote monitoring. Its accuracy is 98.50% of fuel tank's volume.
