Water application example
Design
Running dry
detection
For applications like water treatment or pumping, some complementary functions are needed.
Diagrams of two typical functions are presented:
Running dry detection b
Detection of excessive or negative pressure b
This function is used to manage low water level
Operation sequences :
1 Normal level = Tempo increase
2 Tempo ending = Start pump
3 Abnormal level = Stop pump
4 Normal level = Tempo increase
5 Tempo nished = Start pump
Note: Delaying compensates sensoroscillations
