12.1.1 Measurement of the Standard Volumetric Flow Rate
If the medium is a gas, the standard volumetric flow rate can be selected as the physical
quantity in addition to the operating volumetric flow rate. The standard volumetric flow
rate is calculated as follows:
V
N
= V * p/p
N
* T
N
/T * 1/K
V
N
- standard volumetric flow rate
V - operating volumetric flow rate
p
N
- standard pressure (absolute value)
p - operating pressure (absolute value)
T
N
- standard temperature in K
T - operating temperature in K
K - gas compressibility factor
Standard pressure p
N
and standard temperature T
N
are set in Special Funct.\SYS-
TEM settings\Gas-Measuring\Normal pressure and Normal temper..
If the operating pressure p and the operating temperature T are measured and fed to the
transmitter, they will be used for the calculation of the standard volumetric flow rate. Oth-
erwise, they will be set in Parameter\Fluid pressure and Medium Temperat..
The gas compressibility factor K is stored in the medium data set. If Other Medium is
selected or if there is no data set for the selected medium, the compressibility factor will
be set in Parameter\Gas compr.factor. Note that the value is to be selected corre-
spondingly to the operating pressure, the operating temperature and the composition of
the gas.
12.2 Toggling Between the Channels
If more than one channel is available/activated, the display for the measured values can
be adapted as follows:
AutoMux mode
- all channels
- only calculation channels
HumanMux mode
Key toggles between the modes.
12.2.1 AutoMux Mode
In the AutoMux mode, the display and the measuring process are synchronized. The
channel on which a measurement is being made is displayed in the upper line on the left.
The measured values are displayed as configured in the program branch Output Op-
tions (see section 12.1). When the multiplexer switches to the next channel, the display
is updated.
The AutoMux mode is the default display mode. It is activated after a cold start.
