Reverse Flow
continued
ON
OFF
used in the flow algorithm calculation
for Advanced Algorithms resulting in
negative flow value.
Note that, for some Primary Elements
and Algorithm Standards, Reverse
Flow may not be applicable. In this
case, flow value will be zero regardless
of the Reverse Flow Calculation option.
Compensation Switch
Absolute Pressure Comp
Switch
ON
OFF
Applicable when Equation Model is
Standard, Algorithm Option is ASME
1989 Algorithms
When ON, use Design Pressure for
Flow Calculation when PV2 (Static
Pressure) goes bad and PV2 Failsafe
is OFF.
When OFF, PV2 has no effect on Flow
Calculation
When Equation model is Dynamic,
Algorithm Option is Advanced
Algorithms or
ASME 1989 Algorithms, this switch is
always ON
Temperature Comp Switch
ON
OFF
Applicable when Equation Model is
Standard, Algorithm Option is ASME
1989 Algorithms
When ON, use Design Temperature
for Flow Calculation when PV3
(Process Temperature) goes bad and
PV3 Failsafe is OFF
When OFF, PV3 has no effect on Flow
Calculation
When Equation model is Dynamic,
Algorithm Option is Advanced
Algorithm or ASME 1989 Algorithm,
this switch is always ON
