5. The flow sensor measures the amount of fuel flowing through the measuring
chamber.
Pressurized fluid coming through the inlet nozzle flow sensor in the inlet of the
measuring chamber, the piston slides along the inner surface of the chamber and
simultaneously slides along the jumper. The piston displaces fluid enclosed in it
inside and outside of the piston chamber through its outlet to the outlet port

11. Порядок установки
1. Assessment of the engine condition
2. Flowmeter mounting
3. Connection of hoses
4. Electric connection
5. Testing operation
6. Precision test

12. Connection of the hoses
Use fuel connectors from
Eurosens mounting kit or
compatible.
Fuel hoses must be
resistant to oils
and fuels
Use only high-quality
mounting kits!

13. Flow meter installation
• Flanges and threaded connections must be clean during
connection.
• When installing, use only new copper sealing from the
mounting kit.
• Fuel lines must be protected from external destructive effects.
• It is not allowed to reduce the internal cross section of the fuel
lines on the bends.
• Fuel hoses on the vehicle must be fixed every 0.5 m.

14. Flow meter installation
• Fuel hoses in length should have a small length margin to
compensate temperature changes.
• Do not install a flow sensor on the elements of the vehicle,
subject to strong vibrations and heat.
• After flow sensor is installed it is necessary to remove air from
the fuel system.
• It is recommended to install extra fine fuel (or filters) filter
before the flowmeter chambers and let engine run for 30
minutes to collect all possible dirt after installation. Then filters
can be removed.

15. Flow meter installation
Installation schemes:
1. “at pressure side”(after fuel supply pump)
2. “at suction side”(before fuel supply pump)
3. Differential scheme

17. Check valve is required only for “P” modifications

18. Advantages
1. Flow meter is installed after fine fuel filter .
2. Fuel is under pressure that make system more tolerable for dirt
particles.
3. Return line still back in tank.
Disadvantages
1. High-pressure pump has less cooling.
2. Temperature of fuel in the return line is lower – less heating of fuel in
the tank
3. Engine warranty will be ended.

20. Check valve is required only for “P” modifications

21. Check air bubbles at hot engine,
at idle, middle and max RPMs

23. Install if needed:
• Radiator
• Deaerator
If it is difficult – just try
Eurosens Delta!
Check:
• ∆t C of fuel
• Air in return line

24. Advantages
1. Minimal changes of the fuel system
Недостатки
1. You may need extra fuel filter to be installed.
2. Increased load at fuel supply pump.
3. Fuel in the tank is not heated anymore by fuel from return line.
4. Troublesome diagnostics of fuel system operation.
5. Air in the return line problem requires deaerator installation

26. Installation of the differential flow meter
(supply chamber at pressure side)

27. Differential method of measurement does high demands to flow meter precision. It is because flow rates
in supply and return line usually are much bigger than engine fuel consumption.
For example, for John Deere tractor , at idling in fuel supply line – 200 liters/hour, in return line – 197
liters/hour. Engine consumption – 3 liters/hour. That means, that for adequate result at idling we need to
measure both fuel flows with precision no more than 0.3%. Moreover, temperature expansion of fuel
(0.7% per every 10 Celsius degrees) add extra error to differential measurement, because temperature
of fuel coming to engine and returning to tank is differ.
That means, you can’t use idea of 2 separate flow meters without good precision and temperature
correction.
Fuel flow meters Delta are made from hard aluminium alloy, measuring chambers have antifriction
coating, in both measuring chambers fuel temperature sensor is installed. Each manufactured flow
meter is pre-calibrated for differential application. Thereby Delta flow meters can provide accurate
results in any mode of engine operation.

28. Advantages
1. No changes in the fuel system.
2. Can be installed at engines during warranty.
Disadvantages
1. More costly flow meter model.
2. Precision is a bit lower.
3. Air in the return line will require deaerator
installation

38. Ground wire must be connected to the same
point with Ground wire of GPS tracker

39. Power wire must be connected to the
same point with Power wire of GPS
tracker. Use 1.5A fuse for flow meter
circuit protection.

43. "Refueling" method
1. Refill fuel tank for max, till visible level of fuel.
2. Leave vehicle to perform its usual operations to consume at least 1/2 of
tank.
3. After it make refueling till max and visible level of fuel in tank again and
measure volume of refueling.
4. Compare volume of refueling with consumed fuel volume by flow meter.

44. "Measuring tank" method
What do you need for this method:
1. Calibrated standard measuring tank of the 2nd precision class, 10 liters
2. Clean capacities, >10 liters
3. 500-1000 ml capacity measuring flask of the 2nd class with a continuous
scale
4. Transparent fuel hoses - 2 pieces.

45. "Measuring tank" method
1. Connect fuel system like shown at this picture

46. "Measuring tank" method
1. Supply and return lines will come from tank capacity with some fuel volume
inside.
2. Start engine and let it run until both fuel hoses will be fulfilled by fuel. No air
bubbles is allowed.
3. Prepare second tank with exactly 10 liters. Attach it to the vehicle tightly.
4. Connect second tank instead of first one. Fuel inside fuel hoses must be
saved.

47. "Measuring tank" method

48. "Measuring tank" method
5. Let vehicle perform its usual duties. No pure idling is allowed.
Vehicle must spend some fuel in idle, normal and hard load more
(preferably). So you can test flow meter in all operation conditions. Be sure
that supply hose fully immersed in fuel and air can't get into fuel system.
6. Stop engine. Remove fuel hoses from measuring tank. Fuel from the hoses
must not drop in measuring tank.
7. Measure rest of fuel from measuring tank and calculate fuel consumption.
Compare it with fuel meter data.

49. Measuring tank with simulated fuel comsumption method
Same with previous method.
•
But you must have much bigger tank capacities - at least 50 liters.
• Make extra fuel hose connection between relief valve and connect it with
extra fuel capacity with 50 liters.
• Install an usual crane in this hose.
• Connect PC with configuration software or Eurosens Display to see instant
fuel rates during experiment.
• See picture

50. Measuring tank with simulated fuel comsumption method

51. Measuring tank with simulated fuel comsumption method
You can now simulate engine consumption by opening crane. Fuel will pass
fuel secondary tank before return chamber of flow meter.
As flow rates in supply/return line is much bigger than fuel consumption - 10
liters is not enough.
Thats why we need least 50 liters for an experiment. Fuel in supply tank will
finish fast.
Measure rest of fuel in supply tank and compare with fuel flow meter data.

52. Fuel theft after sensor
What you can see:
Fuel consumption is always higher than normal

53. Fuel theft after Direct
flow meter
What you can see:
Sometimes fuel consumption is
abnormal

55. For fuel flow meter installation
you will need
USB Destination 01 adapter
Configuration
