Accurate response to fluid dynamics: When the flow rate of water or other non- liquid exceeds the set value, the flow switch drives the micro-switch through the paddle to realize the connection and disconnection of the SPDT load, effectively controlling the status of the circuit and ensuring the stability of the system. 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, fire protection systems, etc., it is an indispensable component in industrial and commercial facilities. Enhanced safety and protection functions: Flow switches play a key role in situations where precise control of liquid flow is required, such as interlocking systems or as "cut-off" protection devices to prevent equipment from operating under abnormal flow conditions, thereby avoiding potential safety risks. . High-quality materials and excellent design: Made of high-quality stainless steel to the durability and long-term reliability of the flow switch. Combined with the optimized design, the performance stability in extreme environments is improved and the service life is effectively extended. Professional specifications and technical support: The flow switch is designed to comply with industrial standards and supports operation within the voltage range of 6-380V. Provide detailed technical guidance and customer support to that users can quickly install and use the equipment smoothly. When the flow exceeds the set value, the fluid drives the blade and the microswitch, and the SPDT can connect the circuit and disconnect other circuits.
