Description of Technoton DUT-E Fuel Level Sensor
is designed for precise fuel level measurement in tanks of vehicles, trucks, tractors, road~building machinery, and fixed installations, DUT-E is used as a standard fuel level sensor or as an additional sensor for AVL, FMS or vehicle tracking systems.
Technoton DUT-E Fuel Level Sensor are used for accurate fuel level and volume measurement in tanks of vehicles and stationary units. DUT-E allows determining current fuel volume and change in volume (refueling or draining) of fuel in the tank.

*** DUT-E CAN.
DUT-E is designed to measure the level of liquid fuel and other nonconductive liquids in the vehicle and stationary tanks.
Application area — used in GPS/GLONASS vehicle monitoring and fuel consumption control systems as additional fuel sensors or as a replacement for standard (factory built-in) fuel level sensors.
DUT-E is installed into a fuel tank of a vehicle. The sensor measures the fuel level in the tank and generates an output signal to forward it to a vehicle tracking device.
The tracking device records and processes the sensor data for further transmission to the telematics server. Server software processes and analyzes the received data to generate analytical reports for a selected period of time.
The user gets the reports on vehicle fuel tank volume and consumption for DUT-E CAN only.
Using the J1939 output protocol makes it possible for DUT-E CAN fuel level sensors to operate as a part of the telematics bus together with DFM CAN fuel flow meters and other factory-built or additional equipment.
With DUT-E CAN in the S6 telematics bus it is possible to obtain real-time monitoring of:
- fuel tank level and volume;
- the total volume of fuel in up to 8 tanks and a separate volume value for each of the tanks;
- fuel temperature;
- sensor specification data (passport);
- presence of water in fuel;
- sensor malfunctions.
The tracking device can receive data from up to 8 DUT-E CAN sensors and up to 4 DFM CAN fuel flow meters via a single CAN interface port. This feature is very important for complicated applications like special utility vehicles as it provides the ability to receive fuel monitoring data from the vehicle itself as well as from special equipment mounted on the vehicle.
DUT-E application as a part of vehicle telematics system allows the operator to:
- receive accurate information on the current amount of fuel in the tank;
- determine the exact refueling amount;
- reveal fuel theft facts;
- monitor fuel consumption rate.
