Application and Character of all kinds of Water Flow Switches

(I) Application of Gravity water flow switch
The gravity type water flow switch can only be installed vertically and cannot be moved during operation. The advantage is that the starting flow is very small, and the switch can be turned on when the pressure is only two meters high. Therefore, it is suitable for the ultra-low water pressure starting domestic gas water heater, electric water heater, water dispenser, etc. which are used in small household appliances to control the automatic start-up and shut-down of water inlet.

(II) Application of Piston type water flow switch
The piston type water flow switch is a representative product of the whole industry. Its starting flow set point is adjustable and widely used in all kinds of field. It can be used in the water-cooling system of various large machinery, to control the automatic start and stop of water supply pump or drainage.

(III) Application of Flap type water flow switch
The most advantage of the flap type water flow switch is that it can be used as a check valve in the reverse direction. The water could pass the flow switch with the whole diameter of pipe, less pressure loss. It has no special requirements for water pressure and quality. It is mainly used in heat pump air conditioning, coal mine drainage, sewage treatment, etc.

(IV) Application of Target water flow switch
Target type water flow switch is a kind of mechanical water flow switch, which can be loading with large working current and can directly load ordinary power electric equipment. Its disadvantage is that when the required starting water volume is low, because the target is too large, it has a great impact on the flow through the pipeline. If the required flow is large, only the target area is reduced, so the starting flow will become high, so it can only be used on some non required water supply and drainage equipment.

(V) application of differential pressure water flow switch
This Pressure Differential type water flow switch can be changed into a water flow switch with stable pressure by adding a few parts inside. Its working performance is quite stable. Now it is mainly used in the hot water dispenser and electric water heater which require constant water volume.

(VI) Application of impeller type water flow switch（Flow Sensor）
Impeller Rotor water flow switch is the most widely used water flow switch at present, because it can automatically calculate the flow water. It can be used in water machine, coffee machine, steam equipment, campus card water selling system, water treatment equipment, cooling system, mechanical equipment, instruments and meters, pharmaceutical (manufacturing) equipment, etc.
