In case the Norsok or API formula will be used:
or
Figure 108 Meter line density, calculated
Precision Full/ Rounded or truncated
dps Precision decimal places
Only the parameters not greyed-out have to be filled for CTSm:
t0
Meter reference temperature
λmh Linear expansion coefficient of the meter housing
λmr Linear expansion coefficient of the meter rotor
Only the parameters not grayed-out have to be filled for CPSm:
p0
Meter reference pressure
Rm Meter inner radius
e Poisson ratio
Em Modulus of elasticity
AT Area of motor rotor
t Wall thickness
6 .10 Gas base density, relative density and specific gravity
6 .10 .1 Base density
Liquid Gas Steam
This section defines the selection process to arrive to an “in use” value for the base density.
There are 3 selections in order of priority with each 4 choices. The SUMMIT will start to check
the first selection. If the value is valid (not in alarm) then this selection will be choosen. If not,
then the second selection will bechecked etc. The last selection is always the keypad value as
defined later, even if all other choices are none.
