Fuel is the biggest running cost of a fleet. Tafi GPS shows how much each vehicle has in the tank, how much it used on every trip and where it was refuelled — from the data the vehicle already produces.
Teltonika trackers such as the FMC650 for trucks and the FMC150 for light vehicles read the CAN bus: fuel level, total fuel used, fuel rate, odometer and engine hours. Tafi GPS turns those readings into consumption per trip, per vehicle and per period.
When the level jumps, Tafi GPS records a refuel with its time and place. You can see every refuel on the map and in the fuel history, next to the trip that followed it.
We set up the demo, connect a tracker and show you the result on your own routes.
When you plan a route, Tafi GPS can suggest fuel stops along it at stations on the fuel-card networks your company uses, so drivers refuel where your cards are accepted.
Harsh braking, hard acceleration, speeding and long idling cost fuel. Eco-driving scores make them visible per driver, so you can talk about facts rather than impressions.
For most modern trucks, no: fuel level and total consumption come from the CAN bus through the tracker. Some vehicles do not publish fuel data on CAN; we check your models before you order devices.
The FMB640 / FMC650 / FMM650 family for trucks and the CAN-capable FMx150 models for vans and cars. See the trackers page for details.
Yes, the mobile apps show the fleet and its data, and alerts reach you wherever you are.
