Frequency Outputs Page 139
1. From the Frequency Outputs Page, choose the desired settings (Refer to Section 6.2.1
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: (see Appendix A)
— 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
3
/pulse)
