electromagnetic flow meter manufacturer

Sewage flowmeter can be widely used in municipal water supply, steel, petroleum, chemical, electric power, industry, water conservancy, water resources and other departments of liquid volume flow measurement, especially suitable for channels, small river flow measurement and environmental protection disposal of sewage measurement.

Electromagnetic flowmeter as a widely used precision instrument products, whether it is the purchase, installation and commissioning and use process need to spend a lot of energy, then, the use of electromagnetic flowmeter should pay attention to what problems?

The correct selection of electromagnetic flowmeter is the prerequisite to ensure the good use of electromagnetic flowmeter. What kind of electromagnetic flowmeter should be selected should be determined according to the physical and chemical properties of the measured body medium, so that the diameter of the electromagnetic flowmeter, flow range, lining material, electrode material and output current, etc., can adapt to the nature and flow requirements of the measured body.

The electrode is the main part of the electromagnetic flowmeter used to measure the liquid flow, therefore, the choice of normal electrode material is directly related to the accuracy of the measurement and the price of the electromagnetic flowmeter.

Electromagnetic flowmeter in the use of precautions and installation requirements

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 transducer in the split electromagnetic flowmeter can form a body or separate type with the sensor, the integrated electromagnetic flowmeter is the integrated electromagnetic flowmeter, the split type becomes the split electromagnetic flowmeter, the flowmeter is a two-way measurement system, and the three integrators are installed: the forward total, the reverse total and the difference total

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.

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.

The use of electromagnetic flowmeters is very wide, and this measuring instrument is used in many industries. Electromagnetic flowmeter is different from the general flowmeter, it follows the principle of electromagnetic induction, can measure the flow of liquid in the pipeline and its velocity.

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

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 grounded with the flange of the electromagnetic flowmeter through the grounding ring to achieve equal potential with the ground to eliminate interference.

A type electromagnetic flowmeter does not require a separate converter; The separation electromagnetic flowmeter type converter is installed near the sensor or the instrument room, the place to choose is larger, the environmental conditions are better than the sensor, and the protection level is IP65 or IP64 (dust and splash level).

Electromagnetic flowmeter in the industry has achieved good results, then as the core accessories of electromagnetic flowmeter – electrode, electrode is contact with the measured medium more accessories, then the cleaning details of the electrode is a crucial point, of course, also pay attention to a certain method.

Electromagnetic flowmeter is a widely used flow meter, in the process of use will inevitably appear some failures, then how to check the cause of the failure and eliminate it, the next Aister to teach you several simple troubleshooting methods.

What are the advantages of electromagnetic flowmeter measurement for sewage measurement? The plug-in electromagnetic flowmeter is composed of two parts: flow sensor and transmitter.

Electromagnetic flowmeters are used to measure the volume flow of industrial liquids and there are many media in industrial liquids, electromagnetic flowmeters are often used to measure the flow of conductive media.

Four physical cleaning methods of electromagnetic flowmeter electrode

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:

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:

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:
