The Explosion-Proof Vane Type Flow Switch is designed to monitor liquid flow in pipelines, ensuring system safety and efficiency. Using a high-sensitivity vane mechanism, it detects fluid movement by shifting when liquid flows, triggering a microswitch to output a contact signal. When no flow is detected, the vane returns to its default position. This durable and reliable flow switch is ideal for applications in hazardous environments, including chemical processing, oil and gas, and industrial water systems, ensuring precise real-time flow monitoring and control.
