The estimated duration of battery life is at least 24 months.
As long as fuel flows through the FUEL-VIEW, the counter will count.
It is recommended to seal pipe connections on the FUEL-VIEW output. If you control seals condition deceiving FUEL-VIEW will be impossible.
There is no reason to drain the fuel in front of DFM, 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: DFM 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 preheate.

The pulse specifications for using our DFM (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
This is because the meter is in power save (standby) mode. All DFM models with display stay in standby mode unless you ‘wake’ the meter with the selector magnet.
Also switching between the counters is carried out through applying the selector magnet to the surface of the meter.

It is not possible to reset the counter values of the FUEL-VIEW DFM B, C or C-K models.
FUEL-VIEW meters can measure the following fluids:
-
Diesel fuel
-
Mineral oil
-
Other types of liquids with kinematic viscosity from 1.5 to 6mm2/sec
- LPG is unfortunately NOT possible
