Frequency or Digital Outputs (FODO2, FODO3, FODO4, FODO5) source options ~
Group 2
• FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B
• Frequency output 1A is the A Phase of Frequency output 1 content (Uncorrected
volume flow rate, Corrected volume flow rate, Average flow velocity, Average speed of
sound, Energy flow rate, Mass flow rate)
• Frequency output 1B is the B Phase of Frequency output 1
• Frequency output 2A is the A Phase of Frequency output 2 content (Uncorrected
volume flow rate, Corrected volume flow rate, Average flow velocity, Average speed of
sound, Energy flow rate, Mass flow rate)
• Frequency output 2B is the B Phase of Frequency output 2 content
• Digital output 1A is based on Digital output1A content (Frequency Output 1 Validity,
Flow Direction, Process Validity)
• Digital output 1B is based on Digital output1B content (Frequency Output 1 Validity,
Flow Direction, Process Validity)
• Digital output 2A is based on Digital output 2A content (Frequency Output 2 Validity,
Flow Direction, Process Validity)
• Digital output 2B is based on Digital output 2B content (Frequency Output 2 Validity,
Flow Direction, Process Validity)
Mode options
• Open Collector (requires external excitation supply voltage and pull-up resistor)
• TTL (internally powered by the meter 0-5 VDC signal)
Channel B Phase options:
• Lag forward, Lead reverse (Phase B lags Phase A while reporting forward flow, leads
Phase A while reporting reverse flow)
• Lead forward, Lag reverse (Phase B leads Phase A while reporting forward flow, lags
Phase A while reporting reverse flow)
Phase A and Phase B output (based on flow direction)
• Reverse flow - output only reports flow in the reverse direction. For frequency outputs,
Phase B of the output is 90 degrees out of phase with Phase A.
• Forward flow - output only reports flow in the forward direction. For frequency outputs,
Phase B of the output is 90 degrees out of phase with Phase A.
• Absolute - output reports flow in both directions. For frequency outputs, Phase B of the
output is 90 degrees out of phase with Phase A.
• Bidirectional - output reports flow on Phase A only in the forward direction and on
Phase B only in the reverse direction.
Maximum frequency for the frequency outputs
• 1000Hz
• 5000Hz
