This document provides information about the DUT-E 2Bio fuel level sensor. The sensor features a third measuring electrode that enables automatic correction of measurement data when switching between fuel types of different permittivity. It can accurately measure fuel volume in tanks regardless of the type of fuel. The sensor also utilizes IoT Burger technology for onboard data processing and temperature correction functions to increase measurement accuracy. It is suitable for use in vehicles and stationary fuel storage tanks.

Fuel level sensor
Specialty
DUT-E 2Bio – smart sensor for accurate fuel volume measurement in fuel tanks of
vehicles and stationary objects.
Distinctive feature of the sensor – third measuring electrode.
It ensures automatic correction of measurement data when switching
between fuel types, which have different permittivity (summer/winter diesel,
biodiesel, kerosene, mineral oil).

Fuel level sensor
Various fuel types (even the same fuel type, but of different quality) differs
according to its permittivity. Data from DUT-E 2Bio allows to detect switching to
other fuel type or filling fuel of different quality.
Tasks/ Detecting fuel type upon its permittivity

Design/ Third electrode and temperature sensor
Fuel level sensor
Third measuring electrode detects changes in permittivity of fuel and runs
automatic measurement correction function.
Digital temperature sensor is placed near third electrode. The sensor allows to
measure fuel temperature in tank with high accuracy.

Features/ IoT BURGER technology
Fuel level sensor
DUT-E 2Bio fuel level sensors are built on IoT Burger technology.
This technology allows maximum “on board” data processing. Raw data is
processed by sensor and only useful information is sent to telematics unit.
IoT Burger technology gives DUT-E 2Bio the following advantages over other sensors:
џ sensor self-diagnostics function, allowing to store information in Events Journal;
џ advanced signal adjustment (filtration, temperature correction & compensation).

Information from DUT-E 2Bio
Data from FLS without temperature correction/compensation
Fuel level sensor
Temperture compensation - automatic function necessary for eliminating influence
of ambient temperature on sensor’s parts, especially on electronic components.
Temperture compensation and correction functions are helping to increase mesurement
accuracy and get temperature-indepent information without false fluctuations on chart.

12. 12
Features/ Signal filtering adjustment
Fuel level sensor
Signal filtering can be adjusted in 0 to 300 s range.
That allows to send accurate data on fuel volume without false fill-up and draining
events to the server. The feature is important when vehicle equipped with DUT-E 2Bio
in fuel tanks is operated on rough terrain.

Installation/ Changing probe length
Fuel level sensor
That means, one standard probe length fits majority of fuel tanks allowing to hold
less pieces in stock and save money on delivery.
Length of DUT-E 2Bio probe (measuring tubes) can be:
shortened by 50%
increased by 50% with
additional sections

Summary
Fuel level sensor
a DUT-E 2Bio measures volume of any fuel type with the same high accuracy
and without any manual re-calibrations.
a DUT-E 2Bio minimizes influence of fuel expansion/shrinking caused by ambient
temperature change on data accuracy thanks to 2 temperature sensors – one
in DUT-E 2Bio’s body and one near third electrode.
a DUT-E 2Bio is suitable for majority of tanks, because sensor length can be
increase/shortened by 50% of initial. Maximum sensor size – 6000mm.
a Firmly mounted in fuel tank and protected from mud and water in the bottom
of a tank.
