Prt B: Port B
Prt C: Port C
A/D Mode Analog to Digital Mode
Boxcar A number between 1 - 64 that represents a signal filtering parameter.
See Chapter 4, Sample Rate
Link Mode
Shows if link mode is enabled or disabled
Flow Min
Minimum calibrated Flow Rate in SFPS
Flow Max
Maximum calibrated Flow Rate in SFPS
dR Min
Delta R value low end cutoff. Should be set to approximately
5 ohms less than the lowest dR corresponding to Flow Max
dR Max
dR value high-end cut-off. Should be set to approximately
5 ohms greater than the dR corresponding to Flow Min
C1 - C5 Coefficients for Characteristic Equation; unique to each probe:
CAL REF OHM Calibration Average Reference Resistance
T0, T1 Temperature Compensation coefficients
T2
Serial number of unit
T3
Customer Order number of unit
The following terms are miscellaneous terms to know:
Full Scale
This is the value that the customer chooses to set the 20mA (or 10 VDC) output to.
The Max Flow value, by comparison, is the highest flow, in SFPS, that the meter was
calibrated to. This value is in the customers units
Power Isolated Input AC power terminals are electrically isolated from all other terminals
Turndown
This is Full Scale divided by the Min Flow
Miscellaneous
Terms
Slope 2
Slope for equation: D/A# = current X Slope 2 + Off 2.
Corresponding to current or voltage output
STD
Density of media (customer’s original request) at standard conditions usually at
Density
14.7PSIA and 70 degrees F: used by firmware for conversion
when a mass flow rate unit is chosen such as LB/HR etc.
Tot. Unit
Unit of Totalizer as NCM or SCF: Note that there is no time unit
