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 liquid flow, including water, ethylene diluent, ethylene glycol, and similar fluids. 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 flow monitoring. They can be used in interlock systems or as protective devices to prevent equipment operation under abnormal flow conditions, helping to avoid potential safety hazards. High-quality materials and excellent design: Constructed from stainless steel and plastic for durability and long-term reliability. Optimized design enhances performance stability in demanding 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 installation guidance and technical support for proper setup and operation. When the flow exceeds the set point, the fluid moves the paddle, triggering the microswitch to activate the SPDT contact, connecting one circuit and disconnecting another.
