Top Mount Float Level Switch – Weatherproof (Outdoor)
We introduce our Weatherproof Magnetic Float Level Switch designed for outdoor and harsh environments. This level switch provides accurate sensing of liquid levels in both conductive and non-conductive liquids, performing reliably even under extreme temperatures, pressures, high viscosity fluids, and corrosive conditions.
Equipped with a cast aluminium weatherproof enclosure, it ensures long service life in open outdoor areas and high-temperature surroundings. The switch uses sealed reed-switch technology for precise ON/OFF level detection.

Working Principle
The magnetic float moves along the stem with changes in liquid level. Reed switches inside the stem are actuated by a magnet inside the float, generating ON/OFF signals.
Models available: Single Level, Dual Level, and Multi-Level (up to four floats).
Construction
The level switch consists of stainless steel stem, magnetic float, stopper, and cast aluminum weatherproof enclosure. It is suitable for outdoor installation in open, high-temperature, or dusty environments.
Enclosure Types
- WP: Weatherproof Cast Aluminium – Outdoor use
