Flow Switch

Flow switch is an automatic control component used to monitor fluid flow status in pipelines. It detects whether liquid or gas reaches the set flow rate. When flow is above or below the threshold, it outputs on/off signal to start/stop equipment or trigger alarm. With simple structure, fast response and high reliability, it is widely used in pump protection, cooling circulation, hydraulic lubrication, HVAC systems to prevent dry running, blockage and ensure safe operation.
