The meter has user-configurable selections for either a frequency
output or digital status (FODO). Use the pull-down menus to edit
these parameters.
(3) Frequency/Digital Outputs:
• FODO1 (four possible output configurations)
• FODO2(eight possible output configurations)
• FODO3(eight possible output configurations)
Frequency or Digital Outputs (FODO 1) source selections:
• FO1A, DO1A, FO1B, DO1B
Frequency or Digital Outputs (FODO 2) source selections:
• FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B
Frequency or Digital Outputs (FODO 3) source selections:
• FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B
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:
