Daniel Liquid Ultrasonic Flow Meters calibration and configuration parameters
•
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
•
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)
Operations
•
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.
