Công tắc lưu lượng, water flow switch, flow switch HFS-25, HFS-20, HFS-15
HFS-25 HFS-20 HFS-15 water flow switch (factory direct supply, reliable quality, sensitivity number)
Guarantee quality, if there are any quality problems, we are responsible for free replacement, we are responsible for all shipping costs, gold quality, excellence
1. Application of water flow switch:
The HFS series water flow switch produced by our company is mainly used in water treatment systems, central air conditioners, water-cooled units, etc. It is suitable for water, ethylene glycol and any other non-corrosive effects on brass and phosphor bronze. A liquid that has no effect on the sealing performance.
2. Working principle of water flow switch:
When the flow rate exceeds the set value, the fluid pushes the paddle and drives the top micro switch through the mechanical device in the water flow switch. The single-pole double-throw switch contact (SPDT) can make one loop conduct. , while cutting off the other circuit. the flow switch typically used require interlocks or " interrupter " protected place.Adjustable trimming and the number of paddle blades of a length , in order to meet the needs of different diameters and flow rates.
2. Overview:
The HFS-25 water flow switch has SPDT output for excellent performance and high reliability.It can be installed in water pipes or liquid pipes that are non-corrosive to copper. When the liquid flow reaches a certain rate, it can be less than the rated point, one of the circuits is closed, and the other circuit is open.
The HFS-25 water flow switch is only used for liquid media above 0 °C, and it can also be used for high-salt liquids, but not for dangerous liquids.
The HFS-25 water flow switch can be installed outdoors and can be installed horizontally or vertically in the pipeline.
The HFS-25 water flow switch is for operational control only. It is necessary to strengthen the responsibility of the installer and the limit control and alarm monitoring system to prevent the occurrence of control failure.
Note: The water flow switch cannot be hit by water. If a quick closing valve is installed downstream of the water flow switch, a throttle must be used.
