K Factor conversions
A.2.1
K-Factor and inverse K-Factor
Equation A-1 Frequency volumetric flow rate K-Factor
and
Equation A-2 Frequency volumetric flow rate inverse K-Factor
where
=
frequency “K-Factor” (pulses/volume
**
) (
Freq1KFactor
and
Freq2KFactor
)
=
frequency “Inverse K-Factor” (volume
**
/pulse) (
Freq1InvKFactor
and
Freq2InvKFactor
)
=
frequency full-scale volumetric flow rate (volume
**
/time unit
*
)
(
Freq1FullScaleVolFlowRate
and
Freq2FullScaleVolFlowRate
)
=
maximum frequency (Hz = pulses/time unit
*
) (
Freq1MaxFrequency
and
Freq2MaxFrequency
)
=
time conversion factor depends on the VolFlowRate Time Unit
data point:
•
volume/second = 1 s/s
•
volume/minute = 60 s/m
•
volume/hour = 3600 s/h
•
volume/day = 86400 s/d
