Flow Switches
Flow Switches are devices used to monitor and control the flow of fluids through a system. They typically consist of a flow sensor, which detects changes in the fluid flow, and a switch or relay, which activates or deactivates a circuit based on the flow rate or volume. Flow switches can be used to signal the presence or absence of flow, to control the operation of pumps, valves, or other devices, or to trigger alarms or shut down systems in case of flow interruptions or abnormal conditions. They are commonly used in industries such as HVAC, water treatment, chemical processing, and fire protection, where flow monitoring and control are critical for system efficiency, safety, and regulatory compliance.
