1 Introduction 1.1 Brief description Ring-11 is a high-reliable and compact level switch, which specializes in liquid level measurement and it is designed with only 40 mm length of the fork body. It is applicable to measure liquid level of vessels, containers, and storage tanks. In addition, based on the design principle, Ring-11 detects vibration frequency change of the fork body when fork body is immersed in medium. Thus, it is suitable to use in foams, air bubbles, viscous liquid and conditions with complex vibrating interference. Ring-11 is particularly aimed to measure the level of low...

(4) Process temperature is as high as 250℃, which is industry-leading. (5) Based on the detection of vibration frequency changing of fork body, the measurement has high reliability. 3 Installation 3.1 Before installation Before installation, please affirm that the instrument model is suitable for the occasion and environment. In order to ensure the instrument work normally after installation, please be aware of process pressure, process temperature as well as the chemical properties of the medium. 3.2 Installation In general, Ring-11 can be installed in any position. The instrument can be...

3.5 Pressure/Vacuum The process fitting must be sealed if there is high pressure or low pressure in the vessel or pipeline. Before mounting, please check if the seal material is suitable for the existing process conditions such as process pressure and process temperature. 3.6 Moisture When the instrument is mounted in outdoors or high humidity areas, please lead the connection cable downwards in front of cable entry, thus the rain and condensation water can drain off and give your instrument additional protection against moisture penetration. See Figure 4 as reference. 4 Electrical...
