The total expenses on fuel system maintenance
(tech support, onsite inspections etc) over years
can be higher than the price of a sensor.
Eurosens Dominator is designed to minimize all
these expenses and extend the system lifecycle.
Fuel level monitoring issue Standard sensor Eurosens Dominator
Fuel level sensor replacement

Eurosens Dominator head is sent
to the customer.
Simple one-step replacement,
no training is required.
Re-calibrate tank after the sensor is
replaced
Required Not required
There is a plenty of short-cutted sensors
(200 mm, 300 mm length etc)
Not possibile for bigger tanks Just order some new electrodes
Dirt inside sensor electrodes... Hard to remove Easy disassembling and cleaning
Cable inlet damage
(typical reason for sensor failure)
Sensor replacement is required

Reliability
■ Eurosens Dominator uses powerful STM32 microcontroller.
■ Dominator AF has both analog voltage and frequency output in one unit, customizable.
■ Dominator RS has both RS232/RS485 interfaces.
■ Optional MODBUS interface.
■ Refillings and fuel thefts autodetection.
■ Thermocorrection algorithms make Eurosens Dominator effective even in extreme
temperature conditions.
■ Every sensor has built-in K-Line interface. Sensor networking mode available.
Smart electronic module
Eurosens Dominator networking
Mechatronics provides more effective solution, because Eurosens Dominator RS has both RS232
and RS485 interfaces onboard, as well as K-Line. Sensors can be connected in Network, where
one sensor works as a master and calculates total fuel volume in all tanks.
Possible connection schemes:
Using RS485 sensor (FLS)
interface for networking.
GPS tracker (TMS) receives total
fuel volume via RS232 interface.

one device connection. So, you can't connect
more than one precise fuel level sensor with

Eurosens fuel flow sensors
Direct and Delta
Usually flow meters are used for:
■ Measuring real fuel consumption.
■ Definition of fuel limits for given tasks.
■ Engine test stands.
■ Motor-hours detection
■ Economy-assistant systems
Eurosens fuel flow meters Direct and Delta are
working on a rotary piston technology that is the
best choice for precise measurement of small
fuel rates (from 1 to 500 liters per hour).
It can measure a real fuel consumption on
vehicles, diesel-generators, ships, boilers etc
together with AVL tracking devices or as
standalone unit.
Some engines have a return fuel line from engine to tank, so it is impossible to measure the fuel
consumption without much re-engineering of the fuel supply system. Mechatronics has two types
of fuel flow meters – single-channel Direct and differential Delta. With two metering chambers
Delta measures both supply and return fuel lines and calculates the difference which is the real
fuel consumption.

Diesel fuel
Heating oil
Motor oil
Other liquids with viscosity from 1.5 to 6 mm²/sec

12. 12 | Axle load sensors
Axle load sensors
Axle load measurement is an important problem in AVL tracking business. Mechatronics
produces axle load sensors for vehicles with air suspension or leaf-spring suspension.
Difference 01 axle load sensor
for air spring suspension
Difference 02 axle load sensor
for leaf spring suspension
There is an input shaft in the sensor
with every turn of which the sensor changes
its output analog signal.
The pneumatic axle load sensor is installed in
a pneumatic suspension system and measures
the current pressure in the suspension balloon.
This pressure is proportional to axle load.
Both axle load sensors are compatible with any AVL trackers with analog (voltage)
measuring input.

Eurosens Dizzi
liquid level sensor
Ultrasonic level sensor Dizzi can be used
for non-contact level measurement of
acoustically transparent liquids.
■ Dizzi allows to measure almost any fluid, including liquefied gas
■ No tank modification is required. All sensor components are placed outside the tank.
It is very important when you measure aggressive, explosive, food and high –
pressured liquids. Nice choose for fuel tank trucks – no need to drill a tank.
■ Smart self-diagnostic algorithm provides stable data without signal attenuation
■ Explosion-proof certified: 0ЕхiaIICT6Ga, [ExiaGa]IIC
■ Output interface: RS485 (LLS, MODBUS)
Benefits
Sample of the fuel level data
The level is measured by
echolocation through the bottom of the tank.
Dizzi is glued to the tank or reservoir, therefore
no changes caused at the original factory
design of the reservoir tank are needed.
Mechatronics exclusive sensor design!

The sensor probe is fixed in the determined position with the help of glue and a metal tie.
Dizzi measures the liquid level correctly even
with some dust on the bottom of the tank, with
no data lost. For further details please refer to
