Guidelines of Compact Liquid Level Switch

Product catalog summary

Introduction
Shenzhen Jiwei Automations Ltd. has developed two models of liquid level switches designed for measuring various liquids with different chemical properties: the Ring-21 Compact Liquid Level Switch for simple conditions and the Ring-11 Liquid Level Switch for more challenging conditions.

Specifications
The Ring-11 Liquid Level Switch features a larger junction case with a modular design and is compatible with both AC and DC power. It has 40mm long tines. The Ring-21 Compact Liquid Level Switch is shorter, with a fork body length of 38mm, a total length of 160.5mm, and a maximum diameter of 31.5mm.

Applications and Limitations
The Ring-21 is suitable for low-cost, economic measurement in simple conditions, capable of withstanding temperatures up to 150°C and fitting into small pipes and confined spaces. It can measure densities as low as 0.7g/cm³. However, its simple design does not meet explosion-proof standards, and its smaller, thinner tines are not ideal for viscous media or challenging conditions. It is not recommended for use with media significantly less dense than water.

Recommendations
For simple measurement conditions, the Ring-21 is adequate. However, for difficult conditions involving viscous media, low-density media, or hazardous environments, the Ring-11 is recommended. The Ring-11's fork has a precisely pre-adjusted harmonic resonant frequency, allowing it to measure densities as low as 0.5g/cm³. It is effective for measuring levels in acids, alkali liquids, syrups, medical liquids, and industrial wastewater.

Additional Features
The forks of the Ring-11 Liquid Level Switch can be coated with an anti-corrosive coating, enhancing its suitability for harsh chemical environments.

Guidelines of Compact Liquid Level Switch-1

Guidelines of Compact Liquid Level Switch For a better measurement solution, Jiwei developed 2 models of liquid level switches for measuring various liquids with different chemical properties: Ring-21 Compact Liquid Level Switch for simple conditions and Ring-11 Liquid Level Switch for difficult conditions. Ring-11 Liquid Level Switch and Ring-21 Compact Liquid Level Switch Ring-11 Liquid Level Switch has a larger junction case with modular design, also adaptive to AC and DC. The tines of Ring-11 is 40mm long, while the overall lightweight structure of Ring-21 is shorter. Ring-21 Compact Liquid Level with the fork body 38 mm long, total length is 160.5 mm and maximum diameter 31.5mm. Shenzhen Jiwei Automations Ltd.

Guidelines of Compact Liquid Level Switch-2

The forks of Ring-11 Liquid Level Switch and Ring-21 Compact Liquid Level Switch Ring-21 Compact Liquid Level Switch is a perfect choice for low-cost economic measurement in simple working conditions. It can withstand 150 ℃ high temperature, and can be mounted in small pipes and confined space applications. The measurable density is as low as 0.7g/cm³. Ring-21 Compact Liquid Level Switch has remarkable advantages, but also limitations. Firstly, because the structure of Ring-21 is compact and short, its circuit and cable connector design are relatively simple, which are not compliant with explosion-proof...

Guidelines of Compact Liquid Level Switch-3

Ring-21 Compact Liquid Level Switch is measuring steam water Lastly, Ring-21 is mainly designed for simple conditions, it is not recommended to use it when medium density is significantly lower than the density of water. To sum up, because the designs of Ring-21 Compact Liquid Level Switch are simple, it mainly meets the measurement requirements of simple conditions. For difficult conditions, such as viscous medium, low density medium and hazardous environment, Ring-11 Liquid Level Switch is a better selection. Its fork’s harmonic resonant frequency has been precisely pre-adjusted to achieve...
