Float switches are used for point-level detection and are commonly used to control other devices such as alarms and pumps when a liquid level rises or falls to a specific point. APG’s Stainless Steel Float Switches are used in a variety of industries and applications including applications in food and beverage, water and wastewater, and chemical industries. APG’s Stainless Steel Float Switches feature NSF 169 approval making them a great selection for food and beverage applications. Below are examples of food and beverage industry applications APG’s Float Switches are used in.

Water and wastewater are often used as shorthand for culinary water delivery and sewage transportation and treatment systems, which works well from a utilities and residential/commercial stand point.
