Choose from our selection of liquid-level float switches, including over 130 products in a wide range of styles and sizes. Same and Next Day Delivery.

Float level switches are sensors with an electrical contact output at a specific liquid level. Applications include level control, valve control, deaerators, condensate tanks, oil level control, drip legs, and boilers.

Mar 28, 2025 · The Model FLS Flood Level Switch is a float operated, liquid level control designed for bracket mounting at floor level sumps or troughs. The proven Magnetrol magnetic coupling is employed to convert float movement to actuate a single snap …

Float switches are special switches that are used for point-based limit level detection in various liquids. They use floats to precisely determine the level inside of a tank. In particular, they are used for controlling pumps and can be used to monitor one or several fill levels.

Float switches are highly effective at detecting point-based limit levels for one or more switch points. WIKA’s portfolio has a float switch for almost all liquid media and interfaces, regardless of foaming, conductivity, pressure, vacuum, temperature, vapors, condensation, boiling effects, turbulence, corrosion, or vibration.

The Float switch FTS20 is a simple and cost-effective solution for point level detection in appropriate fluids. It is used in tanks and vessels as a pump protector or level alarm in open basins, e. g. in sewerage treatment plants.

Float level tilt switches provide reliable level detection in open vessels, sumps, and ponds. These switches include a 7-meter cable, a weight, and an EPDM rubber float with a micro-switch that changes state as the float rises or falls +/- 45° from its nominal position.

The float level switch is mounted or floating on the media to be sensed. Suppose it is floating on a liquid. Whenever the float is in a straight position or above a straight position, it means the level is proper.

Float level switch. The Magnetrol float switch mechanism uses a mercury tilt bulb, tilted by a magnet’s attraction to a steel rod lifted into position by a float. The float directly senses liquid level, positioning the steel rod either closer to or farther away from the magnet.
