Will I see fuel drains?
Yes, with a fuel level sensor or a CAN reader. A regular tracker shows route, mileage and idling, but not litres in the tank.
Level sensor or flow sensor?
A level sensor sees refills and drains. A flow sensor counts how much the engine burned.
Which sensor for a truck?
BI FLSENSOR 700 — for tanks up to 700 mm high. 1500 mm — 5,080 UAH, 3000 mm — 6,800 UAH, for taller tanks. We don't put a tank sensor into cars or vans — fuel comes from CAN.
