Working Principle 

 The product is equipped with a magnetic piston inside. When water flows, it pushes the piston forward, and the external magnetic reed switch detects the magnetism on the piston to output a switching/contact signal, i.e., the contact closes. When the water flow is too small or there is no flow, the small magnet inside repels the magnetism on the piston to reset and disconnect the signal.

Usage Precautions 

 1. If the water contains particles, debris, or iron fragments, a filter mesh must be installed at the inlet. 

 2. Avoid installing the flow switch near magnetic or ferromagnetic objects and in environments with strong vibrations to prevent false actions. 

3. Do not exceed the maximum voltage and current, otherwise the flow switch will be damaged. 

4. Do not directly load pumps, motors, solenoid valves, alarms, or contactors. Use an intermediate relay instead, otherwise the flow switch will be damaged. 

5. Do not use the product without understanding it. Contact a technician for clarification before use.
