UQK Series Stainless Steel Flange Float Level Switch: Durable and Precise Liquid Level Detection for Industrial Applications

May 14, 2026

Accurate and reliable liquid level detection is crucial in industrial automation, process control, and fluid management systems. The UQK Series stainless steel flange float level switch is a high-quality float switch designed for precise liquid level monitoring in tanks, reservoirs, and vessels. Its stainless steel construction, flange mounting design, and durable float mechanism ensure reliable performance even in demanding industrial environments.


Product Overview

The UQK series is a stainless steel float level switch with a flange mounting design, making it ideal for direct installation on industrial tanks and vessels. The float moves with the liquid level, triggering the internal reed switch, which provides a stable ON/OFF signal for pump control, alarms, or automation systems.

Key Features:

  • Flange-mounted stainless steel design: Ensures secure installation and easy integration into industrial systems
  • Durable stainless steel construction: Corrosion-resistant and suitable for harsh industrial environments
  • Reliable magnetic reed switch: High sensitivity and stable operation
  • Robust float mechanism: Provides long-term stability and accurate level detection
  • Customizable installation height: Allows adaptation to various tank sizes
  • Compact design: Suitable for both large and small tanks

Working Principle

The UQK float level switch operates using a reed switch mechanism:

  1. The stainless steel float rises or falls with the liquid level.
  2. A magnet inside the float actuates the reed switch inside the stem.
  3. The reed switch outputs an ON/OFF signal to pumps, valves, or alarms.

This simple yet robust mechanism ensures stable, reliable, and maintenance-free operation, even in industrial fluids that may be corrosive or contain impurities.


Industrial Applications

The UQK series is suitable for a wide range of liquid level monitoring applications, including:

  • Water tanks and reservoirs
  • Chemical storage tanks
  • Oil and fuel tanks
  • Wastewater treatment systems
  • Industrial automation equipment
  • Boiler water monitoring
  • Pump control systems

Its stainless steel construction and flange design make it particularly suitable for heavy-duty industrial applications, where durability and stability are essential.


Advantages of the UQK Series

  • Corrosion-resistant stainless steel construction ensures long service life
  • Flange-mounted design allows secure, leak-free installation
  • High-sensitivity magnetic reed switch provides accurate and reliable level detection
  • Robust and compact float delivers stable operation even with liquid turbulence
  • Maintenance-free design reduces downtime and operating costs

Compared to standard float switches, the UQK series provides enhanced durability, precise control, and easy integration into industrial systems.
