DUT-E fuel level sensor is 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 is used in GPS tracking and vehicle telematics systems as additional fuel sensor or as a replacement of standard built-in (factory) fuel level sensor. When used as a part of telematics system, DUT-E provides reliable and accurate information on current fuel volume in the tank and to reveal misuse and fuel theft from tank. DUT-E also gives a general overview on fuel usage by vehicle or stationary unit.
Fuel Level Sensor Tasks
Monitoring of tank refueling and fuel draining
Fuel theft prevention
Fuel consumption monitoringAdvantages of DUT-E Fuel Level Sensor
Built on new technology – IoT Burger
DUT-E fuel level sensors are built on IoT Burger technology and support S6 technology. IoT Burger technology allows maximum “on board” data processing. Raw data on fuel level is refined by sensor and only useful information is sent to telematics unit. This allows to avoid blind spots caused by data transfer interval and get more accurate and stable information in telematics software.
Multi-tank measurement with S6 technology
S6 technology is used for creating a network of IoT devices within an object. DUT-E are compatible with S6 technology and that allows to create a network of sensors on one vehicle/stationary unit. This feature allows to monitor fuel volume in several tanks at the same time and also gives an opportunity to connect other telematics onboard equipment. Main advantages are that all sensors are configured and all data are sent through a single cable, connected to CAN-port of telematics device.
Cut to required length, extend to 10 000 mm
Measuring probe of DUT-E can be cut to the required length and/or extended up to 10 000 mm. Length cutting/extension can be done right at the place of installation, just before mounting to fuel tank. That increases installation speed, reduces costs for sensor delivery to place of installation, what is especially important for projects where fuel tanks are higher than 1000 mm.
DUT-E Fuel Level Sensor Installation
DUT-E can be installed either in the flange of the standard fuel sensor 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.
When installation of DUT-E is complete, you should 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.
Install DUT-E in geometric center of a fuel tank.

What is the purpose of the DUT-E fuel level sensor?
The DUT-E fuel level sensor measures the fuel level and volume in the tank. Based on DUT-E readings, it is possible to determine the refueling volumes, the current fuel remaining, and the volumes of fuel drained from the tank.
What types of machinery is the DUT-E fuel level sensor designed for?
The DUT-E fuel level sensor is used on commercial vehicles and heavy machinery equipped with one or more fuel tanks. Tank shape is not a limiting factor — since DUT-E has no moving parts, it can be installed in tanks with rectangular, cylindrical, or irregular geometries.
How to use data from the DUT-E fuel level sensor?
Typically, the DUT-E fuel level sensor is connected to a vehicle monitoring terminal or a telematics gateway, which transmits the data to cloud-based GPS tracking software. The cloud software generates reports on fuel refueling volumes, refueling locations, and fuel drain volumes (e.g., theft from the tank). This information enables prompt response to improper vehicle operation, as well as detailed analysis of fuel costs and operational efficiency for individual units and the entire fleet.
Is it mandatory to connect the DUT-E fuel level sensor to a monitoring terminal?
Not necessarily. The wireless DUT-E S7 fuel level sensor transmits data via Bluetooth to a smartphone application, while the DUT-E GSM — a 2-in-1 solution — can send information directly to cloud-based software via the Internet, as well as to the user’s smartphone via SMS and email.
What is the operating principle of the DUT-E?
DUT-E is a capacitive-type fuel level sensor consisting of an outer and an inner tube, with a dielectric liquid (e.g., diesel fuel) filling the space between them. This design, with no moving parts, allows DUT-E to be used in tanks of various shapes and enables easy adjustment of the measuring section’s length.
Can DUT-E measure CO₂ emissions during engine operation?
No, DUT-E measures only the fuel level and volume in the tank. It cannot directly measure fuel consumption or determine CO₂ emissions — these tasks are handled by DFM fuel flow meters.
What is the key distinguishing feature of Technoton’s DUT-E fuel level sensors?
The Technoton product line includes four types of DUT-E fuel level sensors, each with different functionality, but all offering the following advantages :
- Transmission of up to 25 parameters — providing highly detailed fuel tank monitoring.
- Easy installation on tanks of various heights — sensor length can be freely cut or extended on-site.
- High measurement accuracy — step of measurements 0.1 mm of fuel level, ±1% error margin, and temperature correction.
- Capability to build a multi-tank monitoring system — up to 32 DUT-E units in a single network using S6 Technology.
- Durable design — no moving parts, over 20 years on the market, quality control certified to ISO 9001.
