The UQK-02-C Float-Ball Level Controller is a marine-grade, horizontal, dual-position level control instrument that has been upgraded and optimized based on traditional level switch designs. Unlike models with fixed ranges, this instrument features a wide, adjustable control range and supports flexible level stroke settings. Utilizing a magnetic-induction mechanical float principle, it enables automatic high/low level limit monitoring, alarm feedback, and synchronized start/stop control for pumping equipment. Thanks to its fully sealed, integrated structure—combined with exceptional resistance to vibration, moisture, and pressure—the instrument is capable of withstanding harsh operating conditions, such as the rolling motion of ships, industrial vibrations, and humid environments. Currently, this product is widely deployed across the marine, petrochemical, and general industrial sectors to provide automatic level control for water tanks, oil tanks, and various other liquid storage vessels.

- **Adjustable Control Stroke, High Adaptability:** Supports an adjustable liquid level control range of 25–550mm, allowing users to freely set high and low limit strokes based on specific on-site operating conditions. This resolves the limitation of fixed, non-adjustable strokes found in standard models, thereby meeting the diverse requirements of various tank types and process control systems.
- **Marine-Grade Sealing and Vibration-Resistant Design:** Manufactured to professional marine standards, featuring an integrated fully sealed structure that effectively withstands seawater moisture, dust, and liquid splashes. It boasts exceptional resistance to vibration and shock, ensuring stable operation during vessel navigation and equipment runtime.
- **High Sensitivity and Stable Signal Output:** Employs a proven magnetic-sensing mechanical mechanism that delivers rapid liquid level response and precise actuation, free from jamming or signal delay issues. The switch signal output remains stable with a low failure rate, making it ideal for long-term, continuous automated control applications.
- **Purely Mechanical Structure, Strong Anti-Interference Capability:** Contains no fragile internal electronic components, rendering it completely immune to electromagnetic interference and voltage fluctuations. It enables 24-hour continuous and stable operation, offering high safety levels and exceptional resistance to environmental interference.
- **Simple Installation, Low Maintenance Costs:** Features a standard horizontal flange mounting method, ensuring a quick and simple installation process that requires no complex commissioning. The overall structure is wear-resistant and durable, with minimal consumable parts, resulting in low long-term operational and maintenance costs as well as an extended service life.
- **Diverse Expansion Options:** Optional self-diagnostic devices and explosion-proof configurations are available to accommodate special operating environments—such as those involving flammable or explosive substances—thereby extending its applicability across a wider spectrum of industrial fields.
