The electromagnetic flowmeter uses the principle of Faraday’s electromagnetic induction law to calculate the flow rate by measuring the induced potential generated by the conductive liquid flowing in the magnetic field, and has the advantages of high precision, no mechanical wear, and two-way measurement.

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.

Typical fault diagnosis and treatment of electromagnetic flowmeter

In order to prevent water resources from being polluted, improve living conditions and protect scarce water resources, most cities have established drinking water projects and sewage treatment plants. In the process of sewage treatment and discharge, the measurement of sewage flowmeter is an important problem. In the process of sewage metering, the selection of sewage flowmeter is very important.

Non-full tube electromagnetic flowmeter is an advanced flow measuring instrument, especially suitable for measuring the flow of non-full tube or partially filled fluid, such as municipal rainwater, wastewater, sewage and so on. The following is a detailed introduction to the non-full tube electromagnetic flowmeter:

Because of the different ways of sewage discharge, the model selected by the sewage flowmeter is also different, there are two ways of general sewage, one is discharged through the pipeline, and the other is discharged through the ditch.

Electromagnetic flowmeter is widely used in the industrial field, in order to make the electromagnetic flowmeter work stable and reliable, accurate measurement, installation needs to be installed in accordance with the correct method.

The selection of circulating water flowmeter is a decision process involving many aspects, which needs to consider the characteristics of circulating water, measurement requirements, environmental conditions, economic costs and the performance characteristics of the flowmeter. Here is a comprehensive analysis and recommendations for the best options:

The grounding ring is a crucial component in the installation of an electromagnetic flowmeter as it helps establish proper grounding and ensures accurate and reliable measurements. Here’s a general guide on how to install an electromagnetic flowmeter grounding ring:

According to the principle formula of the electromagnetic flowmeter, the induced signal potential is not affected by the change of conductivity and temperature, pressure, density and viscosity when the liquid conductivity is uniform. However, in the actual measurement, due to the following reasons, the electrical conductivity will also have some impact on the measurement.

The choice of water flow meter is a comprehensive consideration process, involving many aspects of factors. Here is a guide to tap water flow meter selection to help you choose the most suitable solution:

1. The sensor structure of the electromagnetic flowmeter is simple, and there are no moving parts in the measuring tube, nor any throttling parts that hinder the flow of fluid. So when the fluid through the flow timing will not cause any additional pressure loss, electromagnetic flowmeter is a very low energy consumption flow meter.

How to correctly select the installation point of the electromagnetic flowmeter

Due to various reasons, some large diameter flowmeters used online can not be tested off-line. It has become an urgent problem to study an online calibration method which is both scientific and effective and ADAPTS to the needs of the field. At present, there are three common methods for online calibration of electromagnetic flowmeters:

Now, the input impedance of the electromagnetic flowmeter converter has improved a lot, and the error is basically not caused by changes in the conductivity of the medium when the conductive liquid is conductive, but for a certain converter input impedance, the conductivity of the measured medium has a lower limit min, which cannot be lower than this lower limit.

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.

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

Electromagnetic flowmeter is composed of electromagnetic flow sensor and electromagnetic flow converter. The main components are measuring tube, electrode, excitation coil, iron core and yoke, housing. The measuring tube of the sensor is a short non-magnetic alloy tube lined with insulating material.

One key advantage of electromagnetic flow meters is their versatility in handling various fluid types and conditions. Since they rely on the conductivity of the fluid rather than its physical properties, these meters are suitable for a wide range of applications, from clean water to corrosive chemicals. Additionally, they exhibit minimal pressure loss, making them an energy-efficient choice for flow measurement systems.

Electromagnetic flowmeter is composed of two parts: sensor and converter. It is based on Faraday’s law of electromagnetic induction, used to measure the volume flow of conductive liquid with an electrical conductivity greater than 5μS/cm, is a kind of induction instrument to measure the volume flow of conductive medium.

The correct selection of electromagnetic flowmeter is the prerequisite to ensure the normal use of the instrument. The diameter, flow range, lining material, electrode material and output current of the electromagnetic flowmeter should be determined according to the physical and chemical properties of the measured flow medium, and can adapt to the field environment and meet the technical indicators and performance requirements.

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 the flow measurement of domestic sewage, it is very important to choose the right flowmeter to ensure the accuracy and reliability of the measurement results. Here are some suggestions to help you choose the right flowmeter for domestic sewage:

Electromagnetic flowmeter is based on the principle of electromagnetic induction, through the electromotive force generated by the conductive fluid through the external magnetic field to measure the fluid flow meter. Electromagnetic flowmeter is widely used because of its high precision and good stability, so the choice of integrated or split electromagnetic flowmeter is particularly important.

Electromagnetic flowmeter selection is generally more concerned with the measurement medium, temperature, pressure, connection form, protection level and whether explosion-proof.
