Technical data

• Digital output 1B is based on Digital output 1B content (Frequency 1B Validity and

Flow Direction)

• Digital output 2A is based on Digital output 2A content (Frequency 2A Validity and

Flow Direction)

• Digital output 2B is based on Digital output 2B content (Frequency 2B Validity and

Flow Direction)

Frequency or Digital Outputs (FODO 3) source

• FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B

• Frequency output 1A is based on frequency content (Actual - Uncorrected Flow Rate

or Corrected Flow Rate)

• Frequency output 1B is based on frequency content and Frequency 1B Phase

• Frequency output 2A is based on frequency content (Actual - Uncorrected Flow

Rate)

• Frequency output 2B is based on frequency content and Frequency 2B Phase

• Digital output 1A is based on Digital output1A content (Frequency 1A Validity and

Flow Direction)

• Digital output 1B is based on Digital output 1B content (Frequency 1B Validity and

Flow Direction)

• Digital output 2A is based on Digital output 2A content (Frequency 2A Validity and

Flow Direction)

• Digital output 2B is based on Digital output 2B content (Frequency 2B Validity and

Flow Direction)

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.
