Configure Frequency/Digital output sources
The meter has three user-configurable selections for configuring either a Frequency output or
Digital output (FODO).
•
FODO1 (eight possible parameter configurations)
•
FODO2 (eight possible parameter configurations)
•
FODO3 (eight possible parameter configurations)
•
FODO4 (eight possible parameter configurations)
•
FODO5 (eight possible parameter configurations)
•
FODO6 (eight possible parameter configurations)
Frequency or Digital Outputs (FODO 1, FODO6) source options
•
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 1 B 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 (Frequency1A Validity and Flow
Direction)
•
Digital output 2A is based on Digital output 2A content (Frequency Output 2 Validity and
Flow Direction)
•
Digital output 2B is based on Digital output 2B content (Frequency Output 2 Validity and
Flow Direction)
Frequency or Digital Outputs (FODO2, FODO3, FODO4, FODO5) source
options

Corrected Flow Rate)
•
Frequency output 1B is based on frequency 1 content and Frequency 1B Phase
•
Frequency output 2A is based on frequency 2 content (Actual - Uncorrected Flow Rate)
•
Frequency output 2B is based on frequency 2 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 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)
Mode options
