Float type level switches are a trusted solution for simple tank level monitoring, thanks to their reliable mechanical design, wide liquid compatibility, and cost-effectiveness. Jiangsu Hongguang Instrument Factory Co., Ltd (Hongguang) is a leading manufacturer renowned for quality and innovation in float type level switches for tanks. These switches operate using the buoyancy principle—a float rises and falls with the liquid, actuating a switch for direct control or alarm functions. Hongguang’s range includes single-point, multi-point, side-mounted, top-mounted, magnetic, and explosion-proof float level switches, serving industries such as water treatment, chemicals, oil storage, and food processing. Compared to ultrasonic or capacitive sensors, float level switches are easier to install, require less maintenance, and are more budget-friendly, making them ideal for applications where simple level indication or control is sufficient. Hongguang’s float type level switches are built from durable materials like stainless steel, PP, PVC, and PTFE, ensuring compatibility with corrosive or food-grade liquids. With flexible installation options, rapid deployment, compliance with international safety standards, and technical support, Hongguang’s float level switches are the preferred choice for simple and reliable tank level monitoring worldwide.
Introduction to Float Type Level Switches for Tank Level Monitoring
Float type level switches are widely employed across industries for simple and reliable tank level monitoring. At Jiangsu Hongguang Instrument Factory Co., Ltd (abbreviated as Hongguang), we have dedicated decades to manufacturing high-quality float type level switches for tanks, offering innovative solutions for liquid level control and automation. In this article, we will explore why float level switches are the preferred choice for simple liquid tank monitoring, discuss their working principles, integration into industrial applications, and highlight how Hongguang’s float type level switches and related products can elevate your process control system.
Understanding the Float Level Switch: Definition and Working Principle
The float type level switch is a mechanical device used to detect the presence or absence of liquid at a specific point in a tank. It relies on the buoyancy principle—a float built from corrosion-resistant materials rises and falls with the liquid level. This movement actuates a switch, providing an electrical signal to trigger alarms, pumps, or control systems. Hongguang’s float level switches stand out due to their robust construction, excellent repeatability, and ease of installation, making them ideal for water, oil, chemical, and fuel tank level monitoring.
