The Flow Switch can be installed in pipelines or liquid conduits that are non-corrosive to materials. Its primary function is to detect the flow of liquid in the pipeline and ensure it meets the required flow rate. It can operate below the set point, with one circuit closing and another opening. It boasts excellent performance and high-precision reliability. The Flow Switch is mainly used in water treatment systems, central air conditioning, and water-cooled units, among other fields.

The principle of the flow switch is that when the flow rate exceeds the set value, the fluid pushes the blades, which then activate the top microswitch through the mechanical mechanism within the flow switch. Its SPDT (Single Pole, Double Throw) function allows one circuit to be closed while simultaneously opening another. This type of flow switch is commonly used in applications requiring interlocking or "cut-off" protection. The number and length of the blades can be adjusted to meet the needs of different pipe diameters and flow rates.
