ReviewWhat is smart fuel theft detector ?
Why to use smart fuel theft detector ?
ReviewWhat is Theft?
The fuel is being stolen from the vehicle's tank through withdrawing using a pipe.
The tank is filled with amount less than written in the bill.
Review
ReviewWhy to use smart fuel theft detector ?
Helps the companies to monitor and identify exactly its fuel consumption periodically and in real-time.Prevents fuel theft from the vehicles tanks.Helps identifying the fuel thief (the driver or other people).
