Accurate response to fluid dynamics: When the flow rate of water or other non-liquid exceeds the set value, the flow switch activates the micro-switch via the paddle to control the connection and disconnection of the SPDT load, effectively managing circuit status and ensuring system stability. Stable operation. High compatibility and wide application: Suitable for measuring and controlling the flow of liquids such as water, ethylene diluent, and ethylene glycol. Widely used in water treatment systems, central air conditioning, water cooling units, and fire protection systems, making it an essential component in industrial and commercial facilities. Enhanced safety and protection functions: Flow switches play a key role in applications requiring precise liquid flow control, such as interlock systems or as "cut-off" protection devices to prevent equipment operation under abnormal flow conditions, helping to avoid potential safety risks. High-quality materials and excellent design: Constructed from high-quality stainless steel for durability and long-term reliability. Combined with optimized design, it delivers stable performance in extreme environments and extends service life. Professional specifications and technical support: Designed to meet industrial standards, supporting operation within a voltage range of 6380V. Includes detailed technical guidance and customer support to ensure quick installation and smooth operation. When the flow exceeds the set value, the fluid drives the blade and microswitch, allowing the SPDT to connect one circuit and disconnect another.
