3.6.1Frequency/Digital outputs

The meter has three user-configurable selections for configuring either a Frequency output or Digital output (FODO).

FODO1 (four possible parameter configurations)

FODO2 (eight possible parameter configurations)

FODO3 (eight possible parameter configurations)

Frequency or Digital Outputs (FODO 1) source

FO1A, DO1A, FO1B, DO1B

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

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

Digital output 1A is based on Digital output1A content (Frequency1A Validity and Flow Direction)

Frequency or Digital Outputs (FODO 2) source

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

Frequency output 1A is based on frequency content (Actual - Uncorrected 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 2A is based on Digital output2A content (Frequency 1A 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)
