Water Flow Switch Sensor
A water flow switch is a crucial component in devices like water dispensers, coffee machines, and household appliances, ensuring precise water flow measurement. Made from a copper body, plastic molding, water rotor, stabilizer, and Hall-effect sensor, it detects flow rates accurately.
When water passes through the rotor, the magnetic rotor spins at a speed proportional to flow rate, while the Hall sensor converts this motion into pulse signals for the controller. This allows smart flow regulation by adjusting valve current, improving efficiency and safety.
Unlike traditional differential pressure valves, this flow sensor eliminates common issues like dry firing and false activation. Key advantages include:
- High sensitivity & fast response
- Long lifespan & reliable performance
- Easy installation & low startup flow
- All materials comply with ROHS test standards.
- Copper material, small size, easy installation.
- The water flow sensor is suitable for water heaters and can be used as a flow switch.
- Stable, high temperature, low water pressure start, safe.
Ideal for smart water control, this water flow switch ensures energy-saving operation and prevents dry running, making it a top choice for modern appliances. Upgrade your system with a durable, accurate, and maintenance-free flow sensor today!
