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, ethylene glycol, etc. Widely used in water treatment systems, central air conditioning, water cooling units, and fire protection systems. Ideal for industrial and commercial applications. Enhanced safety and protection functions: Flow switches provide critical control in applications requiring precise liquid flow monitoring, such as interlock systems or as protective devices to prevent equipment operation under abnormal flow conditions, helping avoid potential safety issues. High-quality materials and excellent design: Constructed from high-quality stainless steel for durability and long-term reliability. Optimized design enhances performance stability in extreme environments and extends service life. Professional specifications and technical support: Designed to meet industrial standards, supporting operation within a voltage range of 6–380V. Includes detailed technical guidance and customer support for easy installation and smooth operation. When the flow exceeds the set value, the fluid drives the blade and microswitch, enabling the SPDT to connect one circuit and disconnect another.
