Installation Skills of Vibrating Fork Level Switch for Vertical Pipeline Vibrating fork level switches are reliable and perfect for overfill prevention, high and low level alarm and pump protection even in the most challenging of applications, such as water conservancy, chemical, environmental protection, food, medicine and other industrial fields. Vibrating fork level switches have no moving parts, needs no calibration and is virtually unaffected by process conditions. Vibrating fork level switches are ideal for pipeline liquid level measurement because of its compact tines. Horizontal pipeline is common and easy to install, but what are the installation skills for vertical pipeline? Difficulties in Liquid Level Measurement of Vertical Pipeline 1. Fast liquid velocity; 2. Liquid is supplied intermittently, and with many bubbles and foams; 3. Narrow space around the pipeline limits the installation position and the method of measuring sensor; 4. High pressure in the vertical pipe has great impact on instrument. Advantages of Ring-11 Liquid Level Switch On basis of the high requirements for liquid level measuring instruments to the working conditions of vertical pipeline, Ring-11 Liquid Level Switch is the ideal choice. Ring-11 Liquid Level Switch is a high reliability control switch specially used for liquid level measurements. The excellent, stable and reliable performance and quality are comparable to imported peers. Based on the fork resonant principle, when a fork vibrates in harmonic resonance comes in contact with measured liquid, its vibrating frequency will greatly decrease. The fork’s Shenzhen JiweiAutomations Ltd.

harmonic resonant frequency has been precisely pre-adjusted to achieve high sensitivity so the lowest measurable density can be as low as 0.5g/cm³, and can withstand the pressure of 64bar. Jiwei Ring-11 liquid level switch is excellent in level measurement for acids like HCL, H₂SO₄, H₂SO₃, and alkali liquids, syrup, medical liquids, industrial wastewater, etc. And particularly, it is suitable for pressured liquefied gas (such as LNG) and applications under complicated working conditions where measured liquid is easy to foaming, bubbling or with high viscosity and under vibration disturbance environment...

length of extension part L1 is about 10 mm, and the end of U-groove should extend into the vertical pipe as L2. The length of L2 is about 10 ~ 20 mm, and the plugging height at the end of U-groove is aligned with the lower part of tines. The specific size of the U-groove should be determined by the size of the pipe as well as the installation position, and the opening of the U-groove should face up to the flow direction. Figure 2: Installation method Ⅱ The design principle is to make the baffle at the end of U-shaped groove blocks the liquid in U-groove. When liquid flows down the vertical pipe,...
