Description
Manual input temperature
expansion factor. Check this to
enter temperature expansion factor
from flow calculation report.
Uncheck this to have the device
auto calculate Fa. Fa is a
Correction factor for the error
resulting from thermal effects on
the Flow element diameter.
Absolute pressure compensation
switch: Applicable to
ASME1989/SMV3000 Standard
algorithms, when pressure failsafe
switch is unchecked. When
pressure compensation is checked,
Design pressure is used for Gas
Equations, Nominal Pressure is
used for Liquid equations when
Static pressure fails. When the
failsafe switch is checked, failure of
pressure will put the device to
burnout when flow is mapped to
AO. For all Dynamic Algorithms
pressure is used regardless of this
switch checked or unchecked.
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
