KFactor
frequency “K-Factor” (pulses/volume**) (Freq1KFactor andFreq2KFactor)
InvKFactor
frequency “Inverse K-Factor” (volume**/pulse) (Freq1InvKFactor and
Freq2InvKFactor)
FreqQ
FullScale
frequency full-scale volumetric flow rate (volume**/time unit*)
(Freq1FullScaleVolFlowRate and Freq2FullScaleVolFlowRate)
MaxFreq
maximum frequency (Hz = pulses/time unit*) (Freq1MaxFrequency and
Freq2MaxFrequency)
(*) TimeUnit
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
(**) Volume
where the volume is selected via data points:
