Example: dST for window function

Condition

Reaction

1 Volumetric flow quantity Q reaches LFC

dST starts, output becomes active

2 dST elapsed, Q reached good range

Output remains active

3 Q above SP (leaves good range)

Output is reset

4 Q again below SP

Output becomes active again

5 Q below rP (leaves good range)

Output is reset again

6 Q reaches again LFC

dST starts, output becomes active

7 dST elapsed, Q has not reached good 

range

Output is reset

8 Q reaches good range

Output becomes active

4.8  Low flow cut-off (LFC)

With the function Low Flow cut-off small volumetric flow quantities can be sup-

pressed 

(→ 10.5.7)

� Flows below the LFC value are evaluated by the sensor as 

standstill (Q = 0)�

4.9  IO-Link

This unit has an IO-Link communication interface which enables direct access to 

process and diagnostic data� In addition it is possible to set the parameters of the 

unit during operation� Operation of the unit via IO-Link interface requires an IO-

Link capable module (IO-Link master)�
With a PC, suitable IO-Link software and an IO-Link adapter cable communication 

is possible when the system is not in operation�
