Fuel level sensor DUT-E

Fuel level sensors

Fuel level sensor DUT-E. Fuel volume and level measurement

Fuel level sensor DUT-E is designed for precision fuel level measurement in all kinds of vehicle tanks, also in tanks of fixed installations.
DUT-E can be used as a part of a fuel monitoring system or to substitute the standard fuel meter of a vehicle.
DUT-E as a part of telematics system is used:

  • to obtain reliable information about current fuel volume in vehicle tank;
  • to define the vehicle fueling volume;
  • to detect fuel theft from the tank;
  • to carry out the remote tank monitoring;
  • to determine fuel consumption.

DUT-E Application for Fleet Monitoring

DUT-E has a standard 5-bolted flange and can be installed either in a place where the standard fuel meter is situated or in a separate aperture in the fuel tank. All necessary details for the installation and sealing of DUT-E sensor are present in DUT-E mounting kit.It is recommended to install DUT-E in the geometrical center of a tank.After the installation of DUT-E is complete, you must perform tank calibration. A calibration table is built in the process, where the output signals of the sensor correspond to correct fuel levels in the tank.
This table is used by a fuel monitoring system to determine how much fuel is in the tank.
DUT-E 232 and DUT-E 485 are able to calculate fuel volume by themselves (either in liters or in per cent values of full tank) and send this data in an output message. To do this, the calibration table must be saved in the memory of the sensor using the SK DUT-E service kit.		 Fuel level sensor DUT-E in a tank
DUT-E fuel level sensor transmits the data about the current fuel level to a GPS tracker. The fleet monitoring system determines the place and the time of this transmission using GPS. The user will get the information about events and the parameters of the vehicle in a form of graphics and tables.
