A fleet owner is a shipping company, which has a huge fleet of tanker trucks (or “fuel trucks” – vehicle, which transport fuel from storage to gas stations and other consumers).

Totally over 1000 truck tankers of various design are involved in fuel transportation: three-axle vehicles with cistern, two-axle freight trucks with three-axle semi-trailer, three-axle vehicles with cistern and a second one on the trailer.

In the same compartment of cistern different fuel types can be transported depending on the day: diesel, gasoline, kerosene.

Tanker truck fuel monitoring system


Unfortunately, some roguish drivers steal fuel by discharging high-quality fuel and by adding extraneous liquids to fuel in the tank or fill the tank with various illegal liquids to keep fuel theft hidden.

  • Actions like that directly cause loses to fleet owner and entail reputation risks.
  • Insurance companies set out so high prices, so that it strongly lowers profitability of transportation.

Fuel tank monitoring allows reducing risks of fuel theft when freighting.

  • Telematics system of tanker truck notifies fleet manager on fuel draining and fuel replacement event in cistern in real-time, thus ensuring prompt detection of manipulations with fuel and preventing fuel theft in future.
  • So much the more insurance companies are ready to lower prices by several times for vehicles, equipped with fuel tank monitoring system.


DUT-E 2Bio differential fuel level sensor provides high accuracy of fuel volume measurement no matter what fuel type is. In case fuel tank was filled with gasoline instead of diesel fuel, measurement inaccuracy won’t get higher than 1%. That means, that you don’t have to re-calibrate sensors, make changes to fuel tank table and carry out additional adjustment of the telematics unit anymore. Messages on fuel type/quality change are sent to the tracker, which notifies fleet manager of this Event via e-mail or SMS. The efforts of roguish drivers to steal or change fuel won’t go unnoticed.

DUT-E 2Bio fuel sensor is installed in each compartment of a cistern. Adjustment of DUT-E 2Bio probe length takes a few minutes during sensor installation.

Tanker truck telematics system with fuel sensor

All sensors together with Helios Advance tracker are united in a single network with power supply and configuration of hardware from one point. Each sensor has a unique address in the network. This provides an opportunity to see both the total volume of fuel in the fuel tanker and trailer, and also level, volume and temperature of fuel in each compartment.

Differential fuel level sensor and additional section

The main goal of the project – to exclude illegal fuel draining and replacement of fuel with cheaper liquids in a cistern. Third measuring electrode of DUT-E 2Bio detects fuel types by predefined pattern, measures fuel level and volume in each compartment of cistern, and sends alarms on fuel drain/change.

Core features of DUT-E 2Bio:

  • possibility of length cutting/extension of measuring tube – savings on delivery to the installation site;
  • S6 Technology – easy mounting and configuration, possibility to create a network of several sensors connected to one CAN-port of telematics device.

achieved by Starcom

  • Totally 2,200 sensors were mounted.
  • Sensors were mounted over a short period.
  • Total costs of installation were low thanks to S6 Technology.

The fleet owner decided to continue equipping all new tanker trucks with fuel tank monitoring system based on DUT-E 2Bio fuel level sensors and Helios Advance trackers.

from telematics system for fuel trucks:

  • 60% costs reduction for cargo transportation insurance;
  • fuel drain volume reduction by more than 2 times;
  • excluded illegal fuel change.

Main benefits of DUT-E 2Bio, which were highly appreciated by Starcom Systems:

  • Unique functionality. The sensor accurately measures fuel level and volume of any fuel type in the tank or cistern. Today truck tankers carry diesel fuel, tomorrow - gasoline, the day after tomorrow - kerosene - and inaccuracy is not more than 1%.
  • Quick and easy installation. Probe length of DUT-E 2 Bio is easily adjusted – there is no neсessity to measure height of cistern compartments beforehand. Thus, installation time is saved.
  • Detailed technical documentation Technical training for our installers conducted in Minsk by Technoton.
