3.6.1 Frequency/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)
