o Entry of the K-factors of the flowmeterA with increasing frequency for the formation of the lineariza-
tion characteristic
o K-factors, associated frequencies and resulting K-factor, see calibration certificate of the flowmeter

...
4.07K-factor
VolumeterA Point7
Example without linearization:
o Point1: Resulting K-factor and frequency at Q
nom
o Point2: Frequency0
Example linearizion with three points:
o Point1: Any K-factor and associated frequency
o Point2: K-factor and associated frequency in ascending order
o Point3: K-factor and frequency at Q
nom
(highest value)
o Point4: Frequency0
Note:
The number of linearization points is limited by the input of the frequency 0.0 . Ensure that the K-
factor and frequency of Q
nom
are entered respectively in the preceding point.
The linearization is extended to 0Hz or to ∞ Hz via the first or last two linearization points resp. and
mirrored into negative values.

tion characteristic
o K-factors, associated frequencies and resulting K-factor, see calibration certificate of the flowmeter
