HFS-20/15/25 Liquid Water Oil Sensor Control Automatic Paddle Flow Switch

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 Specifications Model HFS 15 1 2 HFS 20 3 4 HFS 25 1 Maximum pressure 16kg f cm2 1600Kpa Insulation resistance Over 100M DC500VMWithstand voltage AC 1500V 1minuteContac
