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 SPDT contact load, enabling circuit connection and disconnection. This ensures stable system operation and reliable performance. High compatibility and wide application: Suitable for measuring and controlling the flow of liquids such as water, ethylene diluent, and ethylene glycol. Commonly 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. They can be used in interlock systems or as "cut-off" protection devices to prevent equipment operation under abnormal flow conditions, reducing potential safety risks. High-quality materials and excellent design: Constructed from stainless steel and plastic 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 to support proper installation and smooth operation. When the flow exceeds the set value, the fluid drives the paddle and activates the microswitch, allowing the SPDT contact to connect one circuit and disconnect another.
