84 UMG70XV3-4EN 12.01.2009
10 Basic Measurement
10.2.5 Medium Temperature
At the beginning of the measurement, the medium temperature is used for the interpola-
tion of the sound velocity and thus, for the calculation of the recommended transducer
distance and for the interpolation of the gas compressibility factor.
During measurement, the medium temperature will be used for the interpolation of densi-
ty and viscosity of the medium.
The value entered here will be used for the calculations if the medium temperature is not
measured and fed to an input of the flowmeter.
10.2.6 Medium Pressure
The medium pressure will be used for the interpolation of the sound velocity and of the
gas compressibility factor. This display is indicated only if SPECIAL FUNCTIONS\SYS-
TEM SETTINGS\MEASURING\GAS-MEASURING has been activated or if GAS-MEASUR-
ING has been deactivated and SPECIAL FUNCTIONS\SYSTEM SETTINGS\DIALOGS/
MENUS\MEDIUM PRESSURE has been activated.
10.3 Other Parameters
10.3.1 Transducer Parameters
If transducers are detected at a measuring channel, input of parameters will be finished.
Press ENTER. The main menu will be displayed.
If no or special transducers are connected, the transducer parameters have to be en-
tered.
Enter the medium temperature. The value must be
within the operating temperature range of the transduc-
ers. Press ENTER.
Enter the medium pressure. Press ENTER.
Select STANDARD to use the standard transducer pa-
rameters stored in the flowmeter.
Select SPECIAL VERSION to enter the transducer pa-
rameters. The parameters have to be provided by the
transducer manufacturer.
Press ENTER.
Note! If standard transducer parameters are used, FLEXIM can not guaran-
tee for the precision of the measured values. A measurement might
be even impossible.
If SPECIAL VERSION is selected, enter the 6 transduc-
er parameters specified by the manufacturer. Press EN-
TER after each input.
