Point level switches are often used as a warning indicator to trigger an alert when a fluid level is either too high or too low within a tank or vessel. A single point level switch detects if a predetermined single liquid level is reached and actuates a switch to notify a user. Single point level switches are available in multiple sensing technologies including float, electro-optic, ultrasonic, capacitive, and water in fuel.
