Key Technologies and Components

Float Switches and Their Functionality

Float switches are one of the most traditional and widely used technologies in drum level sensors. They operate on a simple yet effective principle: a buoyant float rises and falls with the liquid level. As the float moves, it activates a switch that signals whether the drum is full, empty, or at a predetermined level. This straightforward mechanism offers reliability and ease of installation, making it popular for various applications. Float switches can be used in water treatment, oil drums, and even chemical storage, making drum gauge them versatile tools in industrial settings. Their simplicity, along with low maintenance requirements, ensures they remain a go-to solution for level detection.
