What are the pulse specifications for the fuel flow meter?
The pulse specifications for using our (models A-K, D and C-K) fuel flow meters with a remote readout unit are specified below.
Model |
Timp min |
Timp max |
Scaled pulse |
 |
| DFM-50 | 360 ms | 18000 ms | 5 ml/pulse | |
| DFM-100 | 180 ms | 8000 ms | 5 ml/pulse | |
| DFM-250 | 180 ms | 9000 ms | 12.5 ml/pulse | |
| DFM-400 | 180 ms | 2400 ms | 20 ml/pulse |
Uhigh= U supply (Ubattery)
Ulow= 0.7V
tlow= 80 ms
Example:
if one takes the model DFM-250D, the highest flow is 60 seconds x 60 minutes / 180 ms = 20.000 pulses per hour = 250 l/h
What are the fuel flow meter operation modes ?
| Operating mode | Flow rate (Q) | B* | C* | |
| Normal Flow Rate |
Idling mode | 0 < Q < 0.1 x Qnom | X | |
| Optimal mode | 0.1 x Qnom < Q < 1.5 x Qnom | X | ||
| Overload mode | 1.5 x Qnom < Q < 2 x Qnom | X | ||
| Tampering Rate |
Tampering mode | 2 x Qnom < Q < 10 x Qnom | X | X |
| Air blowing submode | Q > 10 x Qnom | X | X |
Qnom = nominal fuel flow (see product page for the right value for your instrument)

How to choose a fuel flow meter?
You should choose a fuel flow meter for vehicles with a modern engine EURO 3/4/5.
The choice of FUEL-VIEW meters for different engines
Engine Power (kW) |
Recommended fuel flow meter |
Recommended mounting kit |
| Until 80 | DFM-50 | Installation kit 2 |
| 80 – 150 | DFM-100 | Installation kit 2 |
| 150 – 300 | DFM-250 | Installation kit 2 |
| 300 – 500 | DFM-400 | Installation kit 4 |
The choice of FUEL-VIEW meters for boiler/burner:
Boiler heat (kW) |
MAX burner flow consumption |
Recommended meter |
Recommended mounting kits |
| 400 | 40 | DFM-50 | Installation kit 2 |
| 800 | 80 | DFM-100 | Installation kit 2 |
| 1500 | 150 | DFM-250 | Installation kit 2 |
| 3500 | 350 | DFM-400 | Installation kit 4 |
You can also use our Product Selector to find the fuel flow meter you are looking for.
What is the replacement interval of the battery of the fuel flow meter?
The estimated duration of battery life is at least 24 months.
How will the fuel flow meter define engine operating time?
As long as fuel flows through the fuel flow meter, the counter will count.
Is it possible to deceive the fuel flow meter?
It is recommended to seal pipe connections on the output of the fuel flow meter. If you control seals condition deceiving FUEL-VIEW will be impossible.
At which place is it necessary to seal a fuel system after the fuel flow meter installation?
It is not necessary to drain the fuel in front of the fuel flow meter, because this volume of fuel is not considered. That’s why you have to seal all the joints of fuel line after the FUEL-VIEW: the fuel flow meter output, the return valve, input to a high pressure fuel pump and its cap. Besides, usually it is necessary to seal the bleed valve on tractors, on YAMZ or KAMAZ engines; it concerns the feeding tubes of the electrotorch prestarting preheater.
Why does the fuel flow meter only show dots on the screen?
This is because the meter is in power save (standby) mode. All fuel flow meter models with display stay in standby mode unless you ‘wake’ the meter with the selector magnet.
Also switching between ‘screens’ is carried out through applying the selector magnet to the surface of the meter.

Is it possible to reset the counter values of the fuel flow meter?
It is not possible to reset the counter values of the FUEL-VIEW DFM B, C or C-K models.
What fluids can be measured by the fuel flow meter?
Fuel flow meters can measure the following fluids:
-
Diesel fuel
-
Mineral oil
-
Other types of liquids with kinematic viscosity from 1.5 to 6 cSt (mm2/sec)
- LPG is unfortunately NOT possible
