Value
C.ProgToFaultEn Decimal BOOL Sets outputs to selected Fault state when the
owner-controller is in Program mode.
0 = outputs use Program mode setting
1 = outputs use fault mode settings
0
C.Operations[0].FilterControl.0 Decimal SINT bit 0 = 1 - apply filter to F0
bit 1 = 1 - apply filter to G0
bit 2 = 1 - apply 1second debounce to G0
0
C.Operations[0].MeterSamples Decimal SINT 50
C.Operations[0].ThresholdControl Decimal SINT Sets flowmeter input threshold control
0 = 50mV threshold (magnetic pickup)
1 = 1.3V threshold (TTL)
2 = 4.0V threshold (PreAmp)
0
C.Operations[0].CalculationType Decimal SINT Sets calculation type
0 = Counts/K-factor x MeterFactor correction
x CCF
1 = Counts/K-factor x MeterFactor correction
x AGA 7 compensation or CCF if CCF is not
equal to 0.0
0
C.Operations[0].AccelCalculation Decimal SINT Number of past samples to use to calculate
an acceleration value.
Sample range is 0 to 255.
50
C.Operations[0].MinDetectableFreq Float REAL User-defined value from 0 - 120,000.
Sets FreqAverage, FreqPeriod, Speed,
GrossRate, and NetRate reading to 0 when
calculated value is less than value entered.
GrossVolume, and NetVolume do not
increment below this value even though
TotalCounts increments over time.
5
C.Operations[0].HighestAllowedFreq Float REAL User-defined value between
MinDetectableFreq and 120,000
When the frequency reaches this level, it sets
the Overspeed alarm limit
3700
C.Operations[0].AccelAlarmValue Float REAL Sets Acceleration alarm limit
-Maximum acceleration (cycles per second
2
)
<AccelAlarmValue< +Maximum acceleration
(cycles per second
2 )
100
C.Operations[0].MeterFactor Float REAL Calibration Adjust for metering reading
applied after K-factor correction. Typically,
this factor is between 0.8 and 1.2 but the
module restricts the value>0.
