Flow monitor

SI0558 SI0564

3 Intended use

The device monitors liquids and gases.

The device detects flow based on the calorimetric measuring principle and switches the output.

The switch point is adjustable.

The typical response time of the device 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.
