DUT-E S7 wireless sensor allows measuring current fuel volume and its changes in a fuel tank. DUT-E S7 is used as a part of vehicle telematics system (GPS vehicle tracking system) and provides reliable information on remaining fuel volume, fuel tank fill-up and draining volumes and helps fleets to set up clear fuel accounting and prevent fuel theft from vehicle’s tank. DUT-E S7 wireless fuel level sensor is also used for fuel level monitoring in stationary tanks.

Wireless data transfer is carried out using S7 Technology via BLE channel. BLE signal from DUT-E S7 can be received by compatible vehicle tracking unit (telematics unit) and/or any Android or iOS device.

DUT-E S7 can also be used as a “night watchman” to alert driver on fuel theft from vehicle’s tank, for example, when resting at night parking.


Monitoring of fuel tank fuelling and draining

Fuel theft detection

Fuel usage monitoring


  • wireless data transfer via BLE (Bluetooth 4.X Low Energy);
  • operation in BLE-radio mode without pairing with receiver – simultaneous data transfer to telematics unit, smartphones, tablets with Bluetooth
  • built-in battery – DUT-E S7 works without external power supply;
  • very low power consumption allows autonomous operation of sensor within 5…10 years;

DUT-E S7 has all the advantages of “classical” DUT-E fuel level sensor models:

  • shortening/extending length of measuring probe;
  • bottom spring for higher rigidity of mounting into tank;
  • screen filter for probe protection from water and mud in a tank;
  • digital self-diagnostics feature for sensor operation quality check;
  • automatic compensation of ambient temperature effect on sensor’s parts.
  • holes for sealing sensor in order to avoid unauthorized dismounting;
  • bayonet mounting plate allows to reduce mounting time;
  • ergonomic grooves for comfortable grip when fastening in bayonet mounting;
  • full set of mounting accessories;
  • conformity with European and national automotive standards.

Fuel Tank Monitor smartphone app

Fuel Tank Monitor app is used for displaying accurate fuel level, volume, temperature and notifications on fuel tank fill-up or fuel draining from tank. All settings for particular DUT-E S7 sensors are stored in the app and can be exported / imported to another device.

Fuel Tank Monitor app features

  • displaying information about the sensors (serial number, firmware version, address within S7 network);
  • saving and uploading sensor profile to / from other android devices;
  • keeping fuel level sensor’ “Empty” / “Full” calibration parameters;
  • keeping fuel tank calibration table;
  • display notifications on fuel tank fill-up / discharging;
  • fuel level sensor self-diagnostics information;
  • data logging from DUT-E S7 fuel level sensor
  • function of automatic defining the remaining distance of the route;
  • function of summation of the fuel volume indications of the specified group of sensors;
  • data display in metric/USC systems of units of measurement;
  • function of automatic defining the time left before the tank is full during fuelling;
  • separate configuration of functions of the Events detection: “Fuelling”, “Discharging” and others.
