4�1 Operating Modes (Mode); 4�2 Select The Medium (Medi); 4�3 Define The Internal Pipe Diameter (Dia) - Autosen AS005 Notice D'utilisation

4.1 Operating modes (ModE)
The unit provides three selectable operating modes for flow measurement:
Operating Medium
mode
REL Liquids, air
LIQU Liquids
GAS Air
The selected operating mode has no effect on the temperature measure-
ment, only absolute values in °C or °F are indicated.
The parameter settings are saved in the respective operating mode, i�e�
when the operating mode is changed, the settings are not lost�
If the operating modes LIQU and GAS are selected:
► Define the medium and the internal pipe diameter (→ 10.2.1).
► If required, calibrate curve of measured values (→ 10.4.9).
4.2 Select the medium (MEdI)
The unit has characteristic curves for different media� Depending on the operating
mode, the following media can be selected in the menu (→ 10.4.3):
Operating mode
Medium REL
H2O x
OIL1* x
OIL2** x
GLYC x
AIR x
4.3 Define the internal pipe diameter (diA)
In the operating modes LIQU and GAS the internal pipe diameter has to be
entered to define the volumetric flow (→ 10.2.2)�
