REV. 10-SIX/SRX
Following reviews the various parameters used in the
HART menu structure and provides fast keys for
accessing this information:
PRIMARY VARIABLE - READ ONLY
Provides information regarding the Primary Variable
(Flow)
PV Measurements
Flow Rate
[Fast Key 1,1,1,1]
Actual measurement of the flow rate in the reference
unit of measurement
PV Loop Current
[Fast Key 1,1,1,2]
Analog value output ranging between 4 and 20 mA
representing the flow rate. The 4 and 20 mA loop
can be verified by using the Loop Test described
below in the Diagnostic section [Fast Key 2,3,1].
PV % of Range
[Fast Key 1,1,1,3]
Provides the value of the flow rate representing the
% of range between the LRV (Lower Range Value)
and the URV (Upper Range Value).
Flow Rate Units
[Fast Key 1,1,1,4]
Units of measurement associated with the flow rate.
Flow Rate Parameters
Low Flow Cutoff
[Fast Key 1,1,2,1]
Any measured flow rate below this value will be set
to 0.
PV URV
[Fast Key 1,1,2,2]
Upper Range Value of the Primary Variable.
Represents the 20 mA value
PV LRV
[Fast Key 1,1,2,3]
Lower Range Value of the Primary Variable.
Represents the 4 mA value. Value is 0.
PV Damping
[Fast Key 1,1,2,4]
Primary Variable Damping factor. Used to smooth
out normal occurring fluctuations in the flow rate.
Values range between .001 and .999 which represents
no smoothing. Lower values increase damping.
K Factor
[Fast Key 1,1,2,5]
K Factor is a linear adjustment factor which may be
used to adjust the flow rate for various reasons
requested by the user. Default is 1.
Dynamic Variables
Flow Rate
[Fast Key 1,1,3,1]
Displays the current flow rate measured by the flow
meter.
Total
[Fast Key 1,1,3,2]
Displays the total flow measured by the instrument.
RTD Power
[Fast Key 1,1,3,3]
Measurement of the power in mW corresponding to
the measured flow rate. Useful for diagnostic purposes
Temperature
[Fast Key 1,1,3,4]
Displays the gas temperature where the sensor is
located
Flow Rate Units
[Fast Key 1,1,3,5]
Units of measurement of the flow rate
Total Units
[Fast Key 1,1,3,6]
Units of measurement of the total flow
Loop Current Bargraph
[Fast Key 1,1,4]
Displays a graphic chart showing the mA output of
the flow rate vs. time – Range between 4 and 20 mA
Percent Range Bargraph
[Fast Key 1,1,5]
Displays a graphic chart showing the flow rate as a %
of range between the LRV and URV
Dynamic Variables Chart
[Fast Key 1,1,6]
Displays a graphic chart showing flow rate in select-
ed units of measurement vs. time
HART IDENTIFICATION
Tag
[Fast Key 1,2,1]
A Tag value entered by the user to identify the flow
meter. Up to 8 digits in length
