FAQWhat can we do? At Ningbo LiHang Intelligent Technology Co., Ltd ,we proudly provide a comprehensive selection of standard, vertical, and horizontal liquid level float switches designed with precision and versatility. These standard float switches come in robust materials like stainless steel and various plastics, such as PVC, polypropylene, or PVDF, catering to different needs. Our float switches ensure tanks or containers maintain a safe fluid level while enhancing efficiency by automating liquid dispensing. Whether for filling or emptying, these switches help achieve the optimal level effortlessly. Customizable in length, they seamlessly adapt to various vessels, from the smallest containers to the largest tanks, and can integrate with alarms for added safety when levels deviate from the norm. Ideal for diverse applications, our versatile float switches are securely mounted into tank walls or extended using reliable extension tubes and liquid-tight fittings, making them adaptable to any tank configuration.How does it work?Many of our vertical liquid level indicators offer flexibility by allowing a simple transition from normally open to normally closed states. This is achieved by easily removing the retainer and flipping the float. In the normally open mode, the switch remains OFF until the fluid lifts the float, contacting the elastic ring and switching it ON. Once activated, the system ensures the tank never runs dry by initiating an automatic emptying process until the switch returns to the OFF position, prompting refilling. This innovative solution opens up endless applications, offering unparalleled reliability and convenience styles to meet your needs.Quality ControlWe have established a full-process strict quality control system. Starting from the careful selection of raw materials, core materials such as stainless steel and engineering plastics all undergo corrosion resistance and strength tests. During production, the float buoyancy accuracy and switch response speed are monitored in real time. Finished products also undergo aging tests simulating extreme working conditions to ensure each product has stable performance and a long service life.After-sales ServiceWe provide a 1-year free warranty. For non-human damage, free repair or replacement is available. Whether it is installation and commissioning guidance or fault diagnosis and solution, we will follow up immediately. We also offer lifelong technical consultation to ensure you use the products with peace of mind and have no worries when encountering problems.Vertical ConfigurationOur vertical float switches offer flexible installation options for both top and bottom tank mounting, covering a full range of PP floats, stainless steel floats, pressure nozzle models, and curved tube designs. These switches enable precise liquid level detection and control, ensuring stable and reliable operation in various industrial and household application scenarios

Horizontal ConfigurationOur product line covers a full range of fluid detection and control solutions, including flow meters, TDS sensors, temperature sensors, proximity switches, water level probes, PP float switches, side-mounted nozzle switches, and stainless steel float switches. These products feature high precision, stability, and durability, and are widely used in industrial automation, water treatment systems, HVAC equipment, and smart home appliances to meet diverse monitoring and control needs.
