Product Description
Features:1. The HFS water flow switch is an imitatioin imported product2. This product is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, glycol and other liquids that have no corrosive effect on copper3. Its role is to protect the place with "cut-off"4. It can be installed on horizontal or vertical pipes, but the two sides of the switch must be no less than the linear length of 5 times the pipe diameter5. Application of water flow switch: Mainly used in water treatment systems, central air conditioning, water-cooled units and other fields, suitable for water, glycol and any other liquids that have no corrosive effect on brass, phosphor bronze and have no effect on sealing performance.
The working principle of the HFS-25 water flow switch: When the flow rate exceeds the set value, the fluid pushes the paddle, and the micro switch on the top is driven by the mechanical device in the HFS-25 water flow switch. Its single-pole double-throw switch contact (SPDT) can make One circuit is turned on, while cutting off another circuit. The water flow switch is usually used in places that require interlocking or "cut-off" protection. The number of blades and the length of the blades can be adjusted to meet the needs of different pipe diameters and flow rates.
