11.6 Menu 4: K-factors flowmeter A
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
o Resulting K-factor, also see rating plate of the flowmeter

Menu item Description
4.01 K-factor
Volumeter A Point 1
...
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.

o Entry of the K-factors of the flowmeter B 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
