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 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 [-
].
Please note that this value must
be < 0
3: Joule Thomson
Isenthalpic expansion using input
'Temperature Exponent' as the
Joule Thomson coefficient
[°C/bar].
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
