The Series L6 Flotect® Liquid Level Switch utilises a paddle or float mechanism (depending on model variant) to detect liquid level presence or absence in pipes, tanks, or vessels. Designed for ease of installation and long‑term reliability, it features corrosion‑resistant materials and a dependable mechanical/electrical switch interface. Suitable for water, oil, or chemical liquids, it provides cost‑effective level sensing where continuous measurement is not required but detection of level change is essential. Use cases include sump filling, pump protection, liquid inventory monitoring, and overflow prevention.
