DEVICE VARIABLES
Device Variable
Number Name Description Units HART Class Code
0,246 Primary Variable Flow GPM,CMH,LPM 66
1,247 Secondary Variable Totalizer Follows PV Units 66
244 Percent Range Output % of FS None 66
245 Loop Current Current Output mA 66
DYNAMIC VARIABLES
Two Dynamic Variables are implemented.
Meaning Units
PV Volumetric Flow Reading GPM,CMH,LPM
SV Totalizer Value based on PV Follows PV units
The PV is derived using a calibrated linearization table applied to A/D converter readings of hall-effect sensors.
The SV is based on a 5ms timer and is updated based on the current reading of flow.
Both PV and SV values are smoothed.
