4 Function
• The unit detects flow based on the calorimetric measuring principle�
• The unit also detects the medium temperature�
• It features an IO-Link interface for parameter setting�
• The unit displays the current process value�
It generates 2 output signals according to the parameter setting:
OUT1:
Parameter setting
-Analogue signal for temperature
-IO-Link interface for parameter setting
OUT2:
Parameter setting
-Analogue signal for flow
4.1 Operating modes (ModE)
The unit provides three selectable operating modes for flow measurement:
Operating mode Medium
Display unit
REL
liquids, air
)
LIQU
liquids
m/s, l/min, m3/h (fps, gpm, cfm)
GAS
air
m/s, l/min, m3/h (fps, gpm, cfm)
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
�
►
