Electromagnetic flow meter is a flow measurement instrument widely used in the field of industrial automation control. According to the installation method and structural characteristics, electromagnetic flow meter can be divided into three types: insertion type, straight pipe type and split type.

Insertion Electromagnetic Flow Meter

The sensor of the insertion electromagnetic flow meter is inserted into the inside of the pipe to measure the flow of the fluid. Insertion type electromagnetic flow meter has the advantages of simple structure, low price and easy maintenance. At the same time, the insertion electromagnetic flow meter also has a wide measurement range and can be suitable for flow measurement of liquids, steam and other media. The disadvantage of the insertion electromagnetic flow meter is that due to the insertion of the measuring sensor, the cross-sectional area of ​​the pipeline is reduced and the pressure loss is large. Therefore, it is suitable for measuring small-diameter pipelines and media with small flow rates.

Straight tube electromagnetic flow meter

The sensor of the straight tube electromagnetic flow meter is installed inside the pipeline and connected to the pipeline to measure the flow of the fluid. Straight tube electromagnetic flow meter has the advantages of high measurement accuracy, good stability and strong anti-interference. At the same time, the straight tube electromagnetic flow meter has a compact structure and does not occupy pipeline space. However, straight-tube electromagnetic flow meter are more expensive and difficult to maintain and install. Suitable for small and medium diameter pipelines and high-demand flow measurement scenarios.

Split Electromagnetic Flow Meter

The split electromagnetic flow meter is divided into two parts: sensor and converter. The sensor is installed inside the pipe and the converter is installed outside the pipe. The split electromagnetic flow meter has the advantages of easy maintenance, simple operation, and flexible installation. At the same time, the split electromagnetic flow meter has the characteristics of multiple output modes and multiple signal processing methods, and can be applied to different flow measurement scenarios. The disadvantage is that it requires multiple connections, which causes certain interference to signal transmission.

Applicable scenarios

Insertion electromagnetic flow meter is suitable for measuring small diameter pipes and medium with small flow rate, such as drinking water, biological treatment, industrial water and other fields. The plug-in electromagnetic flow meter has the characteristics of easy installation, no need to change the pipeline structure, high measurement accuracy and good stability. Since the insertion electromagnetic flow meter needs to insert a probe into the pipeline, it has certain requirements for the pipeline material and is only suitable for pipelines of some specific materials.

Straight tube electromagnetic flow meter is suitable for measuring medium and large diameter pipes and medium with large flow rate, such as chemical industry, steel, electric power and other fields. Straight tube electromagnetic flow meter has the characteristics of easy installation, no need to change the pipeline structure, high measurement accuracy, and wide adaptability. The straight tube electromagnetic flow meter has a compact structure and has no requirements on the pipe material, so it has a wide range of applications.

Split electromagnetic flow meter is suitable for measuring large-diameter pipelines and media with large flow rates, such as cement, mining, chemical industry, steel and other fields. The split electromagnetic flow meter consists of a sensor and a signal converter. The signal converter can be placed in a safe area and is suitable for some hazardous situations. The split electromagnetic flow meter has the characteristics of easy installation, high measurement accuracy, and wide adaptability. Because of its complex structure, the price is relatively high.

In general, electromagnetic flow meter have the advantages of high measurement accuracy, good stability, and wide adaptability, and can meet the flow measurement needs in various fields. When purchasing an electromagnetic flow meter, you need to choose the appropriate type and specifications based on the actual situation, and consider its advantages, disadvantages, and applicable scenarios in order to choose the most suitable product.
