TASK

Customer had to deal with problem of fuel monitoring in fuel tanks of buses. Accurate
data on remaining fuel helps to plan operating hours of bus on the route, place and
time of refuellings.

Passenger buses are designed in such a way that passenger cabin has maximum
capacity. Place for fuel tanks is chosen "according to leftover principle" - near wheel
arches, in the space between sheathing and body panels. It is impossible to mount fuel
tank of large capacity with a form of parallelepiped or cylinder there. Therefore, fuel
Bus fuel tanks
tanks of buses are usually of a complex shape.
It is impossible to accurately measure fuel level in such fuel tanks using only standard float sensor. Lever of standard sensor cannot
move freely throughout the entire height of fuel tank.

Approximate fuel monitoring with an accuracy of "half a tank, give or take" did not suit the customer. So, it was necessary to install
accurate fuel tank monitoring system with measurement inaccuracy not more than ± 1%.
