2. Working Principle of Jiwei Ring-11 Tuning Fork Level Switch
The Ring-11 tuning fork level switch works based on the vibration frequency principle. The fork body vibrates at its natural resonance frequency. When the fork is exposed to air, it vibrates at one frequency. When the liquid level rises and covers the fork, the vibration frequency changes. The electronic module detects this frequency shift and converts it into a switching signal.
This principle is widely used in liquid point level detection because it is simple, stable, and reliable. It does not require complex calibration and is not easily affected by changes in dielectric constant, conductivity, bubbles, pressure, or moderate changes in viscosity.
Ring-11 Tuning Fork Level Switch uses precision tuning and anti-interference technology to ensure accurate liquid level detection. It is suitable for both high-level and low-level detection, including:
High-level alarm, low-level alarm, overfill protection, dry-run protection, pump protection, tank level control, pipeline liquid detection, and safety interlock applications.
Because Ring-11 and VEGASWING 61 are both vibration-based tuning fork level switches, Ring-11 can replace VEGASWING 61 in many existing applications, provided that process connection, electrical output, approval requirements, and installation conditions are matched.

This compatibility helps Ring-11 serve as a practical replacement for imported tuning fork level switches in both new and existing plants.
10. Reliable Performance in Foam, Turbulence, Vibration, and Buildup
Industrial sites are rarely perfect. Liquid surfaces may be turbulent, foamy, sticky, or unstable. Pumps may create vibration. Agitators may cause splashing. Process media may form buildup on the sensor.
Ring-11 is designed to remain reliable under these difficult conditions. It supports stable liquid level detection in the presence of:
Foam, turbulence, vibration, medium fluctuation, and buildup.
This advantage is important for real-world applications. Many level switch failures are not caused by normal liquid detection, but by process interference. A level switch that performs well only in clean water may not be reliable in actual chemical or industrial processes.
Ring-11’s anti-interference design helps reduce false alarms and missed alarms. This can reduce unnecessary shutdowns, protect pumps, prevent overflow, and improve production continuity.
For users replacing VEGASWING 61 in challenging applications, Ring-11 provides dependable field performance.
