Monitors liquid flow by means of a paddle. A spring supported stainless steel paddle located in the flow chamber and moved by medium in the direction of flow. When a preset flow rate is approached, the magnet connected to the paddle nears the magnet with opposite poles, which is outside the flow chamber linked to a microswitch. This generates a limit value when the actual flow rate is above or below a nominal value preset.

Character:
* Relatively small pressure loss
* Insensitive to pollution
* Powerful micro switch
* All functional parts made of stainless steel
* Site adjustable switch
* Designed to switch on flow fall
* Generally used as an indication that some thing is not working and can be found in cooling circuits, HVAC, Laser circuits, Thermal exchange (water chillers)
