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 (m3/hr or ft3/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/m3 or pulses/ft3)

Vol/pulse:

Freq1InvKFactor

Freq2InvKFactor

Options: Non-configurable, calculated value (m3/pulse or ft3/pulse)
