From the 
Frequency Outputs Page
, choose the desired settings (Refer to 
 
for a detailed discussion on configuring the frequency outputs.)
Content:
Frequency output 1
Frequency output 2
Options: 
Actual flow rate (Uncorrected), Standard flow rate (Corrected), Average flow 
velocity, Average sound velocity, Energy rate, or Mass rate 
Direction: 
Reverse, Forward, Absolute, or Bidirectional
Channel B zero on error Options: 
unchecked - Not Forced to Zero When Invalid (FALSE) checked - Force to Zero 
When Invalid (TRUE) This option controls whether the frequency channel B 
output is zeroed when the frequency content is invalid. 
Channel B phase: 
Options: Lag Fwd, Lead Rev, Lead Fwd, Lag Rev
Guidelines: This option determines the frequency channel B phase relative to 
the corresponding channel A phase depending upon the flow direction.
Maximum frequency for frequency output: 
Options: 1000 Hz (1000) 5000 Hz (5000)
Full scale volumetric flow rate used with output:
Options: Enter a flow rate value (m
3
/hr or ft
3
/hr)
Guidelines: This option specifies the volumetric flow rate associated with the 
maximum frequency (discussed above) and with the maximum frequency 
determines the frequency’s K-factor.
K-factor: (
Freq1KFactor 
freq2KFactor
Options: Non-configurable, calculated value (pulses/m
3
 or pulses/ft
3
)
Vol/pulse:
Freq1InvKFactor
Freq2InvKFactor
Options: Non-configurable, calculated value (m
3
/pulse or ft
