How to Choose the Flange Size of Magnetic Level Gauge

I. Introduction

In the field of industrial automation and measurement and control, magnetic level gauge, as a common liquid level measurement instrument, is widely used in petroleum, chemical, water treatment, food, medicine and other industries. Magnetic Level Gauge through the magnetic flap with the liquid level change and flip, realize the liquid level visual display, has a simple structure, easy to install, low maintenance cost and other advantages. However, in the installation and selection process of Magnetic Level Gauge, the flange size selection is a crucial part. In this paper, we will discuss the principle and method of flange size selection of magnetic flap level meter and its importance in practical application from the perspective of professional manufacturer.

Ⅱ. The Basic Concept of Magnetic Level Gauge Flange

The flange is a key component of the Magnetic Level Gauge connected with the container or pipeline, which carries the weight of the level meter and bears the role of medium pressure, temperature and other environmental factors. The flange size selection directly affects the installation stability, sealing and measurement accuracy of the level meter. Therefore, in the selection process, according to the actual working conditions, media characteristics and measurement requirements and other factors, a reasonable choice of flange size.

Ⅲ. The Principle of Flange Size Selection

Match with the container or pipeline: the size of the flange must be matched with the interface size of the container or pipeline to ensure that the level meter can be stably and firmly installed in the container or pipeline.

Withstand pressure and temperature: the flange must be able to withstand the working pressure and temperature of the medium to ensure that no leakage or damage occurs under extreme working conditions.

Sealing performance: the sealing performance of the flange is an important factor to ensure its normal operation. When selecting flanges, flanges with good sealing performance should be prioritized to reduce the risk of leakage.

Convenient installation and maintenance: the size selection of flanges should also take into account the convenience of installation and maintenance. Too large a flange will increase the installation difficulty and cost, while too small a flange may affect the measurement accuracy and stability of the level meter.

Ⅳ. The Method of Flange Size Selection

Determine the interface size of the container or pipeline: first of all, it is necessary to clarify the interface size of the container or pipeline, including the diameter, thickness, connection method and other parameters. This is the basis for selecting the flange size.

Calculate the working pressure and temperature: according to the working pressure and temperature of the medium, calculate the pressure and temperature range that the flange needs to withstand. This helps to determine parameters such as the material, thickness and sealing method of the flange.

Selecting the appropriate flange standard: according to international or industry standards, select the appropriate flange standard. Commonly used flange standards include DN (German Standard), ANSI (American Standard) and so on. When choosing, the installation environment and usage requirements should be fully considered.

Determine the connection mode of flange: the connection mode of flange includes welding, bolting and so on. When selecting, the suitable connection method should be determined according to the actual situation to ensure a solid connection between the level meter and the vessel or pipeline.

Consider the convenience of installation and maintenance: when choosing the flange size, the convenience of installation and maintenance should be fully considered. Too large a flange will increase the installation difficulty and cost, while too small a flange may affect the measurement accuracy and stability of the level meter. Therefore, in the selection process, it is necessary to consider various factors to find the most suitable flange size.

V. Practical Application Case Study

In order to better illustrate the importance of flange size selection, this paper will analyze several practical application cases as examples. These cases cover different industries, different working conditions of the Magnetic Level Gauge applications, through the comparison of different flange sizes on the performance of the level meter, to further elaborate the flange size selection principles and methods.

Case 1: Application of magnetic flap level meter in a chemical plant storage tank.

The medium in the storage tank of the chemical plant is corrosive liquid with high working pressure and temperature. During the selection process, we chose DN100 flanges with welded connections according to the tank’s interface size, working pressure and temperature parameters. In the actual application, the level meter shows good stability and sealing performance, effectively avoiding the risk of leakage.

Case 2: Application of a water treatment plant pool magnetic level gauge.

The medium in the pool of the water treatment plant is clear water, with low working pressure and temperature. During the selection process, we chose DN50 flange with bolt connection according to the interface size of the pool and the installation environment. The level meter is easy to install, low maintenance cost, and high measurement accuracy, which meets the measurement needs of the plant.

Ⅵ. Conclusion

The size selection of the flange of the Magnetic Level Gauge is an important part of ensuring the normal operation of the level meter. In the selection process, the flange size must be reasonably selected according to the actual working conditions, media characteristics and measurement requirements and other factors. By selecting the appropriate flange standard, connection mode and consider the convenience of installation and maintenance, etc., the flange size should be selected according to the actual working conditions.
