The mass flowmeter directly measures the mass flow of the medium through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. To accurate measurement data, there can be no influencing factors, but when using the flow meter can not avoid the influence of some factors, in short, some factors affect the measurement and solution of the mass flow meter.

Electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines, including the volume flow of acid, alkali, salt and other highly corrosive liquids.

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.

Ultrasonic flowmeter in the industrial automation more and more wide range of use, many owners in the purchase of ultrasonic flowmeter, will encounter some easy to ignore in the selection of parameters, in view of this phenomenon, Aister instrument to give you a few ultrasonic flowmeter selection needs some parameters.

The measuring accuracy and stability of the electromagnetic flowmeter is directly related to whether the electromagnetic flowmeter housing is grounded.

Thermal mass flowmeters are widely used in various industries due to their ability to measure the flow rate of gases accurately. Here are some applications of thermal mass flowmeters across different industries:

Electromagnetic flowmeter has very good characteristics, can solve other flowmeter is not easy to apply problems, such as dirty flow, corrosion flow measurement, so the application of electromagnetic flowmeter is more and more extensive. To choose a suitable electromagnetic flowmeter for yourself, you must have an understanding of it.

With the continuous production progress of the reform and opening up industry, it has been applied in more and more industries, and the vortex flowmeter is widely used in large, medium and small pipeline water supply and drainage, industrial circulation, and sewage treatment.

Electromagnetic flowmeter, with high precision, long life characteristics, in chemical industry, environmental protection, metallurgy and other fields and industries have been applied. However, in the process of use, due to the influence of many factors, it is easy to cause the inaccurate measurement results of the electromagnetic flowmeter.

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.

How to correctly select the installation point of the electromagnetic flowmeter

1. After power-on, there is fluid flow in the pipeline, but the vortex flowmeter has no signal output

Installing and debugging a thermal mass flowmeter correctly in the early stages is crucial to ensure accurate and reliable measurements. Here are some precautions to take during installation and debugging:

There is no doubt that the Coriolis mass flowmeter can measure viscosity. As is known to all, the basic quantities such as temperature, density and mass flow rate can be obtained through the mass flowmeter, which provides the necessary conditions for measuring the viscosity of the medium.

What are the problems encountered when electromagnetic flowmeters are used in paper mills

Nominal diameter: DN25～DN300mm
Accuracy: liquid ±1.0%, gas (steam) ±1.5%, plug-in ±2.5%

LUGB flange clamped vortex street steam flowmeter is a commonly used structure, its body itself does not have a connection flange, in connection with the pipe, the flowmeter clamped between two special flanges, and then bolted.

Vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. There are special phenomena and problems in the process of measurement. One of the key problems is that the vapor density value deviates too much from the design value, which brings significant measurement errors to the measurement results. At present, the density measurement instrument with mature technology has not been successfully applied, which brings certain difficulties to the steam flow measurement.

Like the flue gas, this medium has a higher temperature, contains more impurities such as solid dust, the general application of large caliber, flow rate range is relatively wide, so the measurement is more difficult, so in the selection and use of flue gas flow timing should pay attention to the characteristics of the power plant flue wind speed, pay attention to the principle of choosing sensors, It is also necessary to pay attention to the wear resistance, corrosion resistance, dirt resistance and high temperature resistance of the sensor, and select the appropriate measurement position to ensure the measurement accuracy.

Ultrasonic flowmeter has the advantage of its working principle. In the large pipeline water flow measurement has a large proportion, today the ultrasonic flowmeter manufacturer Aister for the installation method and main points of the external clamp ultrasonic flowmeter for you to make the following explanation.

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.

The following is an analysis of the typical applications and technical advantages of vortex flowmeters in gas measurement.

Electromagnetic flowmeters, commonly known as magmeters, are a sophisticated and versatile type of flow measurement device widely used in industrial applications.

Usually there is more or less a mixture in the fluid in the measurement of some occasions. In general, in the presence of a small bubbling flow of oil and gas bubbles, it is still able to work normally, but the measurement is a fusion of the volume of oil bubbles, if the proportion of oil and gas rises to have caused a projectile flow, then the electrode may be covered by gas, resulting in the circuit is disconnected, the output shake is more likely to be directly damaged.
