Flow-X General functions - fxVCone_C
Pressure Location 1: Upstream
Input 'Pressure' represents the pressure
at the upstream pressure tapping (p
1
).
Since the absolute pressure is usually
measured at the upstream tapping this
is the most common setting.
2: Downstream
Input 'Pressure' represents the pressure
at the downstream tapping (p
2
).

Temperature
Location
1: Upstream
Input 'Temperature' represents the
upstream temperature (t
1
).
2: Downstream
Input 'Temperature represents the
temperature at the downstream
tapping (t
2
).
3: Recovered
Input 'Temperature' represents the
downstream temperature at a location
Where the pressure has fully recovered
(t
3
).
Since temperature measurement is
usually downstream of the flow device
this is the most common setting.

Temperature
Correction
This parameter specifies if and how the
temperature should be corrected from
downstream to upstream conditions (or vice
versa)
1: (1-
)/
Isentropic expansion using (1-
)/
as
the temperature referral exponent
2: Constant
Isentropic expansion using input
'Temperature Exponent' as the
temperature referral exponent [-]
3: Joule Thomson
Isenthalpic expansion using input
'Temperature Exponent' as the Joule
Thomson coefficient [°F/psi].
This method is prescribed by ISO5167-
1:2003.

Density Location
This parameter specifies if and how the
density should be corrected from
downstream to upstream conditions (or vice
versa).
1: Upstream
Input 'Density' represents the density at
the upstream pressure tapping (
1
).
2: Downstream
Input 'Density' represents the density at
the downstream tapping (
2
).
3: Recovered
Input 'Density' represents the density
downstream at a location Where the
pressure has fully recovered (
3
).
