FAQ
What 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?
A temperature sensor utilizes the physical characteristics of its own material that change with temperature (such as changes in resistance, voltage, electromotive force, etc.) to convert temperature signals into electrical signals. For example, a thermistor: as the temperature rises, its resistance decreases. By detecting the change in resistance value and then processing it through a circuit
Quality Control
We've built a strict full-process quality control system. Starting with careful raw material selection, core materials like stainless steel and engineering plastics 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 Service
We 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 Configuration
Our versatile Vertical float level sensors offer unmatched flexibility with installation options at both the top and bottom of the tank. Achieve seamless system performance by effortlessly managing tank emptying and filling with minimal downtime. Designed with various mounting threads, these sensors are crafted from premium materials including stainless steel and plastics, catering to diverse budgetary and operational needs.


Horizontal Configuration
Engineered for precision, our Horizontal float type level switches are expertly mounted on the side of the tank, offering unparalleled accuracy in setting your desired liquid level, regardless of tank size or shape. With an array of mounting threads and material options, we tailor-make the ideal solution to meet your specific requirements, ensuring optimal performance and reliability.
