Features: This flow switch is an automatic element that controls flow in pipes, which can be used on water treatment system, central air conditioning, water cooled chiller and relative industries.Applicable fluid includes water, ,oil or other liquid not classified as hazardous or corrosive.Flow control value is adjustable, repeat action point is stable.Protection grade is IP54; the contactor life is up to 100,000 times.When flow rate exceeds set value, fluid drives blade and micro switch, the SPDT contact can connect a circuit and disconnect other circuit.It can not be used when fluid temperature drops below freezing point.Specifications: Output Form: Micro switch SPDT output Micro Switch: 15A(max.), 250VAC/DC Contact Lifespan: 100,000 times Model: HFS-20Thread: R3/4Fluid: Water, oilFluid Temperature: 1℃~100℃ Max. Pressure: 10bar IP Grade: IP54 Package Includes: 1 x Flow Switch3 x PaddlesNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
- Automatic Flow Detection: This SPDT paddle type flow switch automatically monitors liquid flow in pipes and triggers circuit changes when flow exceeds the set point, making it ideal for protecting pumps and chillers in water treatment or HVAC systems.
- Adjustable Sensitivity: The flow control value of this automatic flow switch is fully adjustable, ensuring precise response to varying flow rates while maintaining a stable repeat action point for consistent performance over time.
- Wide Fluid Compatibility: Designed for use with water, , oil, and non-hazardous liquids, this flow sensor switch suits diverse applications including central air conditioning, industrial chillers, and fluid circulation systems.
- Durable Construction: Built with an IP54-rated enclosure, this paddle type flow switch resists dust and splashing water, while its micro switch mechanism supports up to 100,000 operation cycles for long-term reliability.
- Easy Integration: Featuring an R3/4 threaded connection and SPDT contact rated at 15A 250V, this flow control switch installs quickly into standard piping systems and seamlessly interfaces with alarms, controllers, or safety circuits.
