Operating Principle
The reed switch type float level switch consists of a magnetic float and reed switch as the main components, which decrease with the fluid level between two stop rings, and its magnetic field actuates a hermetically sealed reed switch incorporated in the guide pipe. It is the advantage of this principle that there is only one moving part, the float, which this actuates the reed switch with its magnetic field without causing any wear and the reed switch itself is totally isolated from the media. Those advantages provide the user with a safe, repeatable, accurate, and high operational reliablity with low maintenance over a long and trouble-free life.

Applications
Fresh water, Sea water, and Low viscosity liquids. Description of Model
