Compact Liquid Level Switch

Ring-21 Compact Liquid Level Switch

 Compact and portable, with overall length 160.5mm, maximum diameter 31.5mm and the fork body only 38mm long.

 Particularly suitable for pipelines and other applications within constricted space.

 With CE certificates. Economical, practical and high cost-effective ratio.

 Strong disturbance resistant ability, not influenced by foam, bubbles, viscosity, vibration and other liquid characteristics.

 Highly reliable because of detecting changed of vibrating frequency of the fork.

  • Ring-21 is an economical compact tuning fork liquid level switch. It is designed with a lightweight compact structure with the fork body 38 mm long, total length is 160.5 mm and maximum diameter 31.5mm. Ring-21 can be applied to the level measurement for vessels, process tanks and storage tanks. It can tolerate foam, air bubbles, higher viscosity and vibrating disturbance. Particularly it is a better choice for small containers or tanks within constricted space. It is also based on the principle that vibrating frequency changes when tines are immersed into measured medium. The measurable density is as low as 0.7g/cm³.


  • Same as Ring-11, Ring-21 Compact Liquid Level Switch is based on fork resonant principle. When fork body which vibrates in harmonic resonance immerses into the measured liquid, vibrating frequency of tuning fork will greatly decrease, so does the output of piezoelectric detection device. An integrated circuit is designed to analyze signal from piezoelectric device and output a switching signal.
