HFS series water flow switch (fine quality high sensitivity)

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 the micro-switch on the top is driven by the mechanical device in the flow switch. The single-pole double-throw switch contact (SPDT) can make one loop conduct. At the same time, cut off another circuit. The flow switch is usually used in places where interlocking or "breaking" protection is required. The number of paddles and the length of the paddle can be adjusted to suit different pipe diameters and flow rates.

2. Overview:

The HFS series water flow switch has SPDT output, excellent performance and high precision 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.
HFS water flow switch is only used for liquid medium above 0 °C, and can also be used for high salt liquid, but not for dangerous liquid.
The HFS water flow switch can be installed outdoors and can be installed horizontally or vertically in the pipeline.
The HFS water flow switch is only used for operational control. 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 flow switch cannot be hit by water. If a quick closing valve is installed downstream of the flow switch, a restrictor must be used.
