Water flow switch

Item: Water flow switch

Short Description: Also named Pressure Control Flow Switch,Pressure Switch,Water Flow Sensor.It always works with water pump to control water pump state(work or stop) depends on its sensor for water flow or not.After open water equipment, the water will flow in water pipe, the flowing water impulse door sensors inside along the shaft to rotate the flow direction of water flow, magnetic device inside rotate with the shaft together, to a certain position, trigger the sensing element, the switch then is turned on, (if you connect it with the water pump),then the water pump starts to work. When the water is turned off, the pump then stop working.The switchs are widely used in the field of solar thermo system,water project,and industry field.

Materials: Brass
Models: AC220V;DC5V;DC12V;DC24V;For connector,please see below chart.

1. Stable. In the design of the induction chamber, magnetron chamber, electronic components separate room to avoid iron pipe materials are adsorbed magnetic material, in order to avoid switching failure.
2, high temperature. The use of high temperature materials production, so that products can be used in hot and cold water conditions.
3, low water pressure start. Return spring with high quality stainless steel, reached a low pressure pump action open.
4. Safety: The electronic components as a control device, so that the product no spark during use, fully enclosed.

Technical Specifications
Use of media: water and physical and chemical properties similar to liquid-like.
Medium pressure: ≤0.6Mpa
Medium temperature: ≤100 ℃

Function: Once open water faucet, water pump starts automatically; Once stop water faucet,water pump stops automatically;

Flow rate requirement: 1,inlet water pressure is more than 0.2Bar; 2, water flowing speed is more than 1.5L /min;

Application :
The switchs are widely used in the field of solar thermo system,water project,and industry field.With this water flow switch,you can let  Solar Hot Water Circulation Pump work only when the water in pipe flows. Once water flow stops,the pump will stop running,too.

General Knowledge on “Water flow switch ”

water-flow-switchFlow switch is a water control for electric water heaters, solar water heaters, air conditioners and other water systems, out of the water control, water heating control, pump control switch, solenoid valve on-off control or water power, water power-control process, when after a certain flow of water is converted to an electrical signal switch type sensors.

Flow switch with high sensitivity, durability and other advantages.
1, the amount (flow rate, which is the liquid flow pressure) to detect whether the liquid flow line and flow of whether the requirements at the same time by switching power contact output (s) off of a signal state.
2, the device by detecting the presence of a signal or by controlling the current from this switch (flow switch electrical contacts pass, off state) to determine the working conditions of the pipeline system, given the appropriate control or operating mode or measure;
3. For example, the central air conditioning water circulation systems, and fire sprinkler system, fire extinguishing system, certain types of liquid circulation cooling system piping, are commonly used in the flow switch for detecting the flow of liquid.
4, the liquid flow in the pipeline for real-time monitoring, to provide digital output, and uses six LED time display fluid flow state, to achieve the following monitoring functions: media flow, reduce / increase the flow rate; media presence / absence; media flow / static; internal monitoring fluid flow conduit size, drying to monitor or prevent pump idle. It is widely used in petrochemical, power, metallurgy, steel, paper, food and mouth products processing, water treatment, battery factory and other industries.
