The E+H Liquiphant FTL41 Level Switch has one measuring system for any liquid, universal use in all pumpable liquids. Simple to use with plug and play functionality based on active sensor technology. It has better long-term stability compared to float switches due to no mechanically moving parts. The FTL41 has repeatability of switching point and no need of maintenance. It is an ideal substitute for float switches, as reliable function is not affected by flow, turbulence, air bubbles, foam, vibration, solids content or buildup.
