Frequency/Digital outputs
The meter has three user-configurable selections for configuring either a Frequency output or
Digital output (FODO).
•
FODO1 (eight possible parameter configurations) [Type 2] [Type 4]
•
FODO2 (eight possible parameter configurations) [Type 2] [Type 4]
•
FODO3 (eight possible parameter configurations) [Type 2] [Type 4]
•
FODO4 (eight possible parameter configurations) [Type 4]
•
FODO5 (eight possible parameter configurations) [Type 4]
•
FODO6 (eight possible parameter configurations) [Type 4]
Frequency or Digital Outputs (FODO 1, FODO 6) source - Group 1
•
FO1A, DO1A, FO1B, DO1B, FO2A, DO2A, FO2B, DO2B
•
Frequency output 1A is the A Phase of Frequency output 1 content (Uncorrected volume
floe rate, Corrected volume flow rate, Average flow velocity, Average speed of sound,
Energy flow rate, Mass flow rate)
•
Frequency output 1B is the B Phase of Frequency output 1Electrical installation
•
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 Output 1Validity and
Flow Direction)
•
Digital output 1B is based on Digital output1B content (Frequency Output 1 Validity and
Flow Direction)
•
Digital output 2A is based on Digital output 2A content (Frequency Output 2 Validity and
Flow Direction)
Frequency or Digital Outputs (FODO 2, FODO 3, FODO 4, FODO5) source - Group 2
•

•
Frequency output 1A is the A Phase of Frequency output 1 content (Uncorrected volume
flow rate, Corrected volume flow rate, Average flow velocity, Average speed of sound,
Energy flow rate, Mass flow rate)
•
Frequency output 1B is the B Phase of Frequency output 1
•
Frequency output 2A is the A Phase of Frequency output 2 content (Uncorrected volume
flow rate, Corrected volume flow rate, Average flow velocity, Average speed of sound,
Energy flow rate, Mass flow rate)

•
Digital output 1A is based on Digital output1A content (Frequency Output 1Validity and
•
Flow Direction)
•
Digital output 1B is based on Digital output1B content (Frequency Output 1 Validity and
Flow Direction)
