| Operating principle |
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
- 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 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.
