Classification of split electromagnetic flow meters

Electromagnetic flowmeter is a kind of induction meter to measure the volume flow of conductive medium, which can be used to measure the volume flow of strong corrosive liquid such as strong acid and alkali and uniform liquid-solid two-phase suspended liquid such as mud, pulp, pulp, etc.

After the initial debugging and normal operation for a period of time, the split electromagnetic flowmeter fails in the operation process, the common causes of failure are: the internal flow sensor connection layer, lightning strikes, environmental changes. Below, the staff of the flowmeter manufacturer will lead you to understand some common faults of the split electromagnetic flowmeter.

Electromagnetic flowmeter is designed for the measurement of conductive liquid instrument, its high accuracy, wide range ratio, internal no moving parts, open flow parts, no pressure loss. Excellent corrosion resistance, high pressure resistance, strong adaptability, has been widely used in various production fields. Because some installation sites are more complex, it is inevitable to produce a variety of interference, Aister instrument to explain several common electromagnetic flow meter anti-interference methods:

The role of electromagnetic flow meter grounding in actual installation. Compared with other flowmeter products, electromagnetic flowmeter has high precision, reliable performance, stable work and excellent anti-interference ability. However, as a precision instrument, in order to meet these high requirements, it is necessary to have strict installation requirements, this article will introduce the electromagnetic flowmeter grounding wire that is often not paid attention to when installing.

Electromagnetic flow meters, also known as magmeters, are advanced devices used for measuring the flow rate of conductive fluids such as water and slurries. These meters operate based on the principles of electromagnetic induction. A magnetic field is generated by the meter’s coils, and as the conductive fluid flows through the meter’s pipe, it generates a voltage proportional to the flow rate. The strength of this induced voltage is directly correlated with the speed of the fluid, allowing for accurate and reliable flow measurements.

Electromagnetic flowmeters generally operate normally for a long time without maintenance after installation, and then require maintenance and daily inspection. The electromagnetic flowmeter can not receive the signal or the signal is too weak is a small problem. So there is no surprise, carefully do the following steps can be solved.

The reason why the measurement error is large is that the amount of oil and suspended matter in the water from the sewage station is high, and the treated sewage has a small amount of oil and suspended matter in the water, and the error of electromagnetic flowmeter measurement is also small.

The temperature resistance range of electromagnetic flowmeters usually depends on their design and application environment. According to the provided information, the temperature resistance range of electromagnetic flowmeters varies:

1, the role of the electromagnetic flowmeter grounding ring: the grounding ring is directly in contact with the medium through the grounding electrode, and then the grounding ring is grounded with the flange of the electromagnetic flowmeter to achieve equal potential with the ground to eliminate interference.

In industry, a flowmeter is a type of flow measurement instrument, and an electromagnetic flowmeter is also a kind of flow instrument. Generally speaking, the types of electromagnetic flowmeters used in different occasions are also different. The classification of electromagnetic flowmeters varies depending on the method. Generally, they are conventionally classified into three types: integrated electromagnetic flowmeters, split electromagnetic flowmeters, insertable electromagnetic flowmeters, and so on. For different occasions, different types of flowmeters are required. The correct selection of electromagnetic flowmeters is a powerful boost in work efficiency.

Electromagnetic flowmeter in use, we need to pay attention to what? Today for you to do a simple description, I hope you pay attention to the following points about the maintenance of electromagnetic flowmeters:

The plug-in electromagnetic flowmeter is an instrument for measuring conductive liquids, which is made based on Faraday’s law of electromagnetic induction. This type of instrument, due to its simple structure, light weight, easy installation and low maintenance, is used to measure the volume flow of non-corrosive (water supply and drainage) conductive liquids in closed pipelines.

Intelligent electromagnetic flowmeter measurement accuracy is high, stable performance, is a very common product in the flow meter, widely used in petroleum, chemical, food and other industries, especially water resources system, almost everywhere can see the figure of intelligent electromagnetic flowmeter, but the measured medium in these occasions is a single liquid, then with intelligent electromagnetic flowmeter can measure the mixture, Aister meter is your answer.

Split electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquid and slurry in closed pipes. Including acid, alkali, salt and other highly corrosive liquids.

The role of the electromagnetic flowmeter grounding ring: the grounding ring is directly in contact with the medium through the grounding electrode, and then grounded with the flange of the electromagnetic flowmeter through the grounding ring to achieve equal potential with the ground to eliminate interference.

The installation of the electromagnetic flowmeter depends on the requirements of the customer’s working conditions, and then select the type, and install it according to the instructions or the guidance of the flowmeter manufacturer’s staff. The following points need to be noted when installing the electromagnetic flowmeter:

Today we bring you an introduction to the cleaning method of the plug-in electromagnetic flowmeter.

The grounding of the electromagnetic flowmeter is equipped with a grounding ring, and then the grounding ring is connected to the pipeline. If it’s lined, you need a third electrode to ground it.

Electromagnetic flowmeter is a speed meter to measure the volume flow of conductive media. While carrying out on-site monitoring and display, it can output standard current signals for recording, adjustment and control, realizing automatic control of detection, and realizing long-distance transmission of signals. It can be widely used in water, chemical, coal, environmental protection, textile, metallurgy, paper and other industries in the flow measurement of conductive liquid. The structure of the instrument has one type and one type.

Electromagnetic flowmeters, also known as magmeters, are devices that measure the flow of electrically conductive fluids using the principles of electromagnetic induction. There are several types of electromagnetic flowmeters, each with its own characteristics and applications. Here are some common types:

Measuring medium: Conductive liquid
Diameter range: DN3mm～DN3000mm
Accuracy: ± 0.5% of the indicated value, optional ± 0.3% or ± 0.2%
Measuring range (Flow rate): 0.01m/s～15m/s

An electromagnetic flowmeter is an instrument that can be used to measure the volume flow of various conductive liquids in pipes and channels. Its characteristics are as follows:

Electromagnetic flowmeters are classified according to the assembly method of converters and sensors, with split type and one type. Split type electromagnetic flowmeter is relative to the integrated, its components are: measuring tube, electrode, excitation coil, iron core and yoke housing. Used to measure the volume flow of conductive liquid and slurry in closed pipes.

Electromagnetic flowmeter as a commonly used flow measurement instrument, the choice of its material is also an important factor. Because in the electromagnetic flowmeter, the part in contact with the medium is only the electrode and the inside of the measuring tube, it is necessary to select the correct electrode and lining material according to the characteristics of different media.

Pipe diameter and pipe vibration

The pipe diameter range of some types of flowmeters is not very wide. Therefore, if it is too large or too small, it will limit the selection of flowmeter varieties. To measure low or high flow rates, a flowmeter pipe diameter different from the pipe diameter size can be selected.

Installing electromagnetic flowmeters correctly is essential for ensuring accurate and reliable flow measurement. Here are some precautions to consider when installing electromagnetic flowmeters:
