Frequency Sweep Level Switch LMFS

Working Principle

The Level Switch LMFS is capable of faithfully detecting industrial fluids and powders using Frequency Sweep technology. Utilizing the resonance of electrical capacitance created by media di-electric and conducitvity, LMFS learns the signature of the media to be sensed and thus performs better than other level detection methods for fluids and powders.
