Flow Switches
Flow switches are essential monitoring devices used to detect and regulate the movement of liquids or gases in pipelines and processing systems. By triggering actions such as pump activation, system shutoff, or alarms, they help protect equipment, maintain safety, and ensure efficient fluid management. Suitable for HVAC, industrial automation, laboratory systems, and water treatment applications, flow switches support consistent performance and enhance workflow reliability across various operational environments.
