Compensation
Mode Shows currently selected
Compensation Mode.This is
user configurable parameter.
Dynamic option allowed on
Advanced Algorithms or
ASME 1989 Algorithms.If
you need to calculate
Standard Flow, Select ASME

applicable.
When Algorithm Option =
ASME 1989 R/W uint8 (Byte 0 :-> Bit 0 to 4 )
0 = ASME-MFC-3
1 = ISO5167
2 = GOST
3 = AGA3
4 = VCONE/WAFER

Discharge
Exponent: Shows Discharge Exponent
setting. This is user
configurable parameter.
When the Reynolds
Exponent is Off, the value
is 0.75. When ON, the value
is 0.5. (Byte 0 :-> Bit 7 )
0 = 0.75
1 = 0.5
Manual Input
Switch 287 Shows currently selected
Manual Input Switch. This is
user configurable parameter.
Configures Manual Input
On/OFF for Density,
Viscosity, Fa, Y, Cd,
Note that only when
Algorithm Option = ASME
1989 Algorithms and
Equation Model =
Standard, AP and TEMP
Compensations can
be set to ON or OFF. This
setting determines
the usage of alternate values
for AP and/or
TEMP for Standard Gas
Flow calculations
when Failsafe setting is OFF. R/W uint8 (Byte 0 :-> Bit 0 to 4 )
Bit 0 :-> 0 = Off, 1 =
