•
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.
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.
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

/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.
