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

→ 10.3.1

 -IO-Link interface for parameter setting

→ 4.7

OUT2: 

Parameter setting

 -Analogue signal for flow

→ 10.2.3

4.1  Operating modes (ModE)

The unit provides three selectable operating modes for flow measurement:

Operating mode Medium

Display unit

REL

liquids, air

%  (of the taught range 

→ 10.2.4

)

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 

(→ 10.2.1)

� 

 

If required, calibrate curve of measured values 

(→ 10.4.7)
