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

Density
Exponent.
This factor is used when density
correction is enabled. The formula
1/
will be used when the input
value is set to 0, else the input
value will be used.
For more details refer to section
function 'ISO5167- Orifice' 'Density
correction'.

Fluid
The type of fluid being measured
1: Gas
2: Liquid
For liquid the expansion factor is
set to 1, i.e. the fluid is considered
to be incompressible.

Drain hole
When input is > 0 then an
additional correction on the orifice
diameter will be applied to account
for the drain hole, as explained
further on.
