Flow sensors are vital components in various industries, providing crucial data on the rate of fluid or gas passing through a system. These sensors come in diverse types, from mechanical to ultrasonic and electromagnetic, each with its unique method of measuring flow. Mechanical flow sensors, like paddlewheel or turbine types, rely on physical movement to gauge flow rates. Ultrasonic sensors use sound waves, while electromagnetic sensors employ magnetic fields. Regardless of type, they all serve to monitor and regulate flow, essential for applications ranging from industrial processes to medical devices and environmental monitoring. These sensors play a pivotal role in ensuring efficiency, accuracy, and safety in fluid and gas handling systems.

A Solenoid valve is an electromechanical device used to control the flow of liquids or gases in a system. Operating at 220VAC, these valves are designed with a brass body, offering durability and resistance to corrosion. When an electrical current is applied to the coil, it generates a magnetic field that moves the plunger or piston within the valve, opening or closing the passage for fluid or gas flow. This type of valve is commonly used in applications such as irrigation systems, heating and cooling systems, and industrial machinery, where precise control of fluid flow is crucial.

The Domestic Reverse Osmosis Purifier with a 7-stage filtration system and UV water sterilizer is a comprehensive solution for ensuring clean, safe drinking water at home. The seven stages of filtration include sediment and carbon filters to remove larger particles and odors, followed by a reverse osmosis membrane to eliminate impurities like heavy metals and contaminants. Then, the water passes through a post-carbon filter to enhance taste and further purify. Finally, the UV sterilizer provides an extra layer of protection by effectively killing bacteria and viruses, ensuring that every drop of water from this system is not just purified but also sterilized. This system is designed to deliver peace of mind and excellent water quality for you and your family.
