3  Functions and features

3.1  Application area 

The unit monitors the flow of liquid and gaseous media�

3.2  Operating principle flow monitoring

•  The unit detects the flow speed to the calorimetric measuring principle and 

switches the output: 

 -output closed if medium is flowing / output open if no medium is flowing�

This applies to the unit on delivery: output = normally open� In case of need you 

can change the output to normally closed (→ 8�2)� It then applies: output open 

if medium is flowing�

•  If the flow speed increases, the switching status changes when the switch point 

is reached� 

•  If the flow speed falls again, the switching status changes if the value "SP 

minus hysteresis" is reached�

The hysteresis changes with the flow speed and it is essentially influenced by 

the set monitoring range� 

It is 2���5 cm/s for the setting 5���100 cm/s (= factory setting), it increases with 

higher flow speeds�

•  The typical response time  of the unit is 1���10 s� It can be influenced by the 

setting of the switch point:

 -Low switch point = quick reaction with rising flow�

 -High switch point = quick reaction with falling flow�

3.3  Communication (IO-Link)

•  The unit is laid out for bidirectional communication� So, the following options 

are possible:

 -Remote evaluation (transmission of the process data)�

 -Remote parameter setting (adjustment / output function)�
