3.4.1.4 Conversion of the flow volume in kilograms via the correction factor
For special applications, the flow meter is able to display the measured volume in a unit of mass such as kilograms.
The correlation between volume V and mass m is ascertained using density r.
m = ρ • V
If the correction factor for volume measurement is known (see chapter C 3.3.1 or correction factor diagram 3),
this is offset with the density r. Convert the correction factor according to the below formula
k
1
: Correction factor after calibration
k
2
: Correction factor for display of the unit of mass
r : Fluid density
k

= ρ • k

+ The unit of volume (litres or gallons) displayed on the flow meter is now no longer valid.
Recommendation: Cover over the displayed unit of volume using a foil indicating the valid unit of mass.
