Which of the following level indicating system sensor types is ideally suited for discrete-level detection as opposed to continuous-level detection?

Correct Answer: Option C — Float actuated limit switches

Float actuated limit switches are designed for discrete-level detection, such as high or low-level alarms. They provide a simple binary output (open or closed) when the liquid reaches a specific point. Unlike continuous sensors, they are ideal for triggering pumps or alarms at fixed, predetermined setpoints.
