What is a water flow switch? And how does a water flow switch work?
The on/off water flow switch for the pipeline booster pump is an automatic water flow switch,it adopts the water flow magnetic control device to control the on-off of the induction element, so as to achieve the function of starting and stoping the water pump. This product has a wide range of uses, mainly suitable for household tap water booster in low water pressure areas, especially for low-pressure ignition of showers, which is more important for laser equipment and environmentally friendly ozone equipment.the Water flow switch controller with model HT-60,HT-120,HT-200,HT-800,HT-801,HT-802,HT-2010 has following features:
Technical features:
1.Stable.In the design, the induction chamber, the magnetron chamber, and the electronic component chamber are separated to avoid the iron-containing materials in the pipeline from being adsorbed by the magnetic materials to avoid switch failure. 2. Withstand high temperature.It is produced with high-temperature resistant materials, so that the products can be used under hot and cold water conditions. 3.Start with low water pressure.The return spring is made of high-quality stainless steel material to achieve the effect of turning on the water pump at low water pressure. 4. Safety: Electronic components are used as control devices to make the product spark-free and fully enclosed during use.
Working principle:
Turn on the water equipment, there is water flowing in the pipeline, and the water flow impulse sensor door rotates along the shaft in the direction of the water flow. The magnetron device rotates with the shaft. When it reaches a certain position, the sensor element is triggered, the switch is turned on, and the household pipeline booster pump starts. When the water flow is interrupted with the shutdown of the water-using equipment, the induction door, under the action of the return spring, drives the shaft and the magnetic control device to rotate together to a certain position, the induction fails, the switch is disconnected, and the household pipeline booster pump stops running.
Technical indicators:
Medium used: tap water or similar liquids with similar physical and chemical properties. Medium pressure: <0.6Mpa Medium temperature: Commen type≤60℃; High temperature type≤100°C Conditions of use: the pressure of water inlet is at least greater than 0.3kg and the water flow speed is at least 2L/min;
Precautions for the use of water flow switch:
1.When installing, pay attention to whether the water flow direction of the pump and the water flow switch is the same. The arrow on the water flow switch points to indicate the direction of the water flow switch.
2.When there are impurities in the tap water pipe, it will cause the water flow switch to fail. Therefore, it is recommended that the newly installed pipeline should be fully discharged to flush out the impurities in the pipeline before connecting to the water pump and the water flow switch. At the same time, it is recommended to install a filter in the pipeline, but the filter should be cleaned frequently to avoid water flow being blocked and the flow rate reduced, which will cause the switch to start and fail.
3.When the flow rate of tap water is insufficient or unstable, the staring and stoping of the water flow switch will cause the water pump to stop and start, and this phenomenon will automatically disappear when the flow rate of tap water is restored.
4. The base of the water flow switch is made of brass material, please do not come into contact with corrosive materials.
5. Do not extend external objects into the water flow switch pipeline to avoid failure.
6. Do not open the internal connector in the water flow switch nut to avoid leakage.
7. When the water flow switch fails, non-professionals should not disassemble it to avoid water leakage, which may endanger the human body from harming the environment.

General Knowledge on “Water flow switch Water pump flow sensor”
What is a water flow switch?
Water flow switch is used for electric water heaters, solar water heaters, air conditioners and other water systems for water circulation control, water inlet and outlet control, water heating control, water pump switch control, solenoid valve on-off control or water outlet power-off, water outlet power-on control and other processes. A sensor device that converts the water flow into an on-off electrical signal after reaching a certain flow rate.
How does flow switch work?
The working principle of the water flow switch When there is water flowing in the water flow switch, and the water flow rate is ≥1.0L/min, the magnetic core in the water flow switch is displaced by the water flow, and the displacement of the magnetic core drives the magnetic source to produce a magnetic control effect, so that the water flow switch outputs “on”. “Signal. The automatic selection of the flow switch is included in the quick and easy selection. The signal is input to the equipment control system, and the control system realizes the control function. When the water flow is less than the starting flow, the water flow switch outputs the “off” signal. The control system produces the opposite control action to the above. In other words: water flow switch When the water flow in the pipeline is greater than 1L/min, the magnetic core will be displaced under the action of the water flow and drive the magnetic source to produce a magnetic control effect, so that the sensor outputs a “1” switch signal, which is input to The equipment control system realizes the purpose of water flow control after power expansion. When the water flow in the pipeline is less than 1L/min, the magnetic core drives the magnetic source to return under the action of the return spring, so that the sensor outputs a “0” switch signal and stops the system. The flow switch has the advantages of high sensitivity and strong durability.
What are features of the water flow switch?
1. The flow switch has the advantages of high sensitivity and strong durability. 2. Detect whether the liquid in the pipeline flows and whether the amount of flow (flow, that is, the liquid flow pressure) meets the requirements, and at the same time output (provide) the on-off state of a signal by the switch electrical contact. 3. The equipment system judges the working status of the pipeline system by detecting whether there is a signal or control current passing through the switch (the on and off state of the electrical contacts of the water flow switch), and gives the corresponding control or operation mode or measures. 4. It can monitor the liquid flow in the pipeline in real time, provide switch output, and use 6 LEDs to display the fluid flow rate status in real time to realize the monitoring function. It is widely used in petrochemical, electric power, metallurgy, steel mills, papermaking, food processing, water treatment, battery factories and other industries.
How to install a water flow switch?
1. Vertical installation. When installed vertically, it should be installed on the pipe section that flows from bottom to top. 2. Horizontal installation. When installed on the upper end of a horizontal pipe, it should be ensured that the medium is full to prevent the probe from only touching the air but not the medium. 3. Invert. When installed at the lower end of a horizontal pipe, it should be ensured that there is no sediment at the bottom of the pipe to prevent the probe from being covered by sediment and unable to fully contact the probe
What are different between Water flow switches and water pump flow sensors?
Water flow switches and water pump flow sensors are essential components of any water system, whether they are needed to maintain or regulate water pressure, or to prevent problems such as flooding. These items are designed to detect the flow of water, and to alert users when there are changes in the flow rate.
Water flow switches act as safety devices that are usually placed in-line with a water pipe or other plumbing system. The switch will detect any changes in the flow rate, and then send a signal to a control system to alert users. This signal can be used to shut off the water supply or to trigger other devices, such as alarms or pumps. Depending on the type of switch, the signal can be a simple mechanical switch or an electrical one.
Water pump flow sensors are very similar to flow switches, except that they are placed in-line with the pump rather than the water pipe. These sensors are also designed to detect changes in the flow rate, but they are better suited to monitoring the performance of the pump itself. For example, if the flow rate changes too quickly, it could indicate that the pump is malfunctioning or that there is a problem with the water source. In this case, the sensor will activate an alarm or other alert system to notify users.
Both water flow switches and water pump flow sensors are essential components of any water system, and they play an important role in ensuring the safety and efficiency of the system. They are relatively inexpensive and easy to install, and they can be used to monitor water pressure, detect changes in flow rate, and alert users of any potential problems.

I started to buy a 150w from another store, and it burned after a few uses. This time I bought a 200w. The water pressure of the water pipe and the small water pump did not start. I baked the small accessories with magnets inside with a lighter, and the angle was small. A little bit, now the water pump starts as soon as the water pipe is turned on. It’s really good.SWuggest to buy bigger watt.
