Let's first understand the application scope of Kobold flow meters in Germany:

Kebao flow measurement is widely used in various fields such as industrial and agricultural production, national defense construction, scientific research, foreign trade, and people's daily lives. In the production of the petroleum industry, flow measurement runs through the entire process from oil extraction, transportation, refining and processing to trade and sales. Any link cannot be separated from flow measurement, otherwise the normal production and trade exchanges of the petroleum industry cannot be guaranteed. In the chemical industry, inaccurate flow measurement can cause an imbalance in the distribution ratio of chemical components, which cannot guarantee product quality and can even lead to production safety accidents. In the production of the power industry, the measurement and regulation of the flow rate of liquids, gases, steam and other media play an important role. The accuracy of flow measurement not only has great economic significance for ensuring the operation of power plants under excellent parameters, but also has become an important link in ensuring the safe operation of power plants with the development of high temperature and high pressure large capacity units. If the instantaneous feedwater flow of a large capacity boiler is interrupted or reduced, it may cause serious dry boiler or pipe burst accidents. This requires flow measurement devices to not only accurately measure, but also to promptly issue alarm signals. In the steel industry production, the flow measurement of circulating water and oxygen (or air) during the steelmaking process is one of the important parameters to ensure product quality. In industries such as light industry, food, and textiles, flow measurement is also indispensable.

The commonly used transducers are external clip on and plug-in. The structure of monaural ultrasonic flowmeter is simple and easy to use, but this flowmeter has poor adaptability to changes in flow distribution. The rapid development of microelectronics and computer technology has greatly promoted the upgrading of instruments, and new types of flowmeters have emerged like mushrooms after rain. So far, it is reported that hundreds of flow meters have been put into the market, and many difficult problems in on-site use are expected to be solved. The development of modern flow measurement technology in China was relatively late, and it was set at the upstream end of the measurement flow channel 6 relative to the holes 11 and 12 to reduce the flow of the measured fluid into the holes 11 and 12; Measurement control component 19 is used to measure the propagation time of ultrasonic waves between ultrasonic transducers 8 and 9; And the calculation component 20 is used to calculate the flow rate based on the signal from the measurement control component 19.

Baode flowmeter should avoid ferromagnetic objects and equipment with strong electromagnetic fields (such as large motors, transformers, etc.) as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor. The flow signal line and excitation line between the sensor spoon converter. However, based on the analysis of damaged components caused by lightning faults, most of the induced high voltage and surge current that caused the fault were introduced from the power supply lines in the control room, and the other two pathways were relatively few. Due to the fact that electromagnetic flow meters have a much higher chance of measuring suspended solids or pollutants compared to other flow meters, the probability of failure caused by the adhesion layer on the inner wall is relatively high. If the conductivity of the adhesion layer is similar to that of the liquid. Common debugging failures are usually caused by improper installation.

The service life of electromagnetic flow meters is generally around 10 years, but the specific lifespan is affected by various factors.

What isKobold electromagnetic flowmeter？

Electromagnetic flowmeter is a widely used flowmeter in modern industry. Its principle is to use Faraday's law of electromagnetic induction to measure flowing conductive liquids. It is widely used in chemical, petroleum, metallurgical, food, pharmaceutical and other fields. Due to its high measurement accuracy, fast response speed, simple structure and easy maintenance, it is highly favored.

What is the service life of Kobold flowmeter?

The service life of electromagnetic flow meters is generally around 10 years, but the specific service life is affected by the following factors:

1. Operating environment: Electromagnetic flowmeters are commonly used in various harsh environments, such as high temperature, high pressure, corrosion, etc. Environmental factors have a significant impact on the lifespan of electromagnetic flowmeters;

2. Operation method: How to correctly use and operate the electromagnetic flowmeter also has a great impact on its lifespan;

3. Maintenance: The maintenance and cleaning of electromagnetic flow meters are key to maintaining their long-term good working condition.

How to extend the lifespan of electromagnetic flow meters?

1. Choose the appropriate electromagnetic flowmeter: According to different usage environments and flow measurement requirements, choose the appropriate electromagnetic flowmeter to ensure its long-term stable operation;

2. Proper use and operation: Before using the flowmeter, it is necessary to understand its relevant parameters and working principles, strictly follow the operating procedures, and apply the operating methods correctly;

3. Timely maintenance: Regularly clean, maintain, and repair the electromagnetic flowmeter to ensure that it is in good condition;

4. Pay attention to management and protection: Electromagnetic flow meters usually need to be addressed in terms of management and protection measures, such as taking lightning protection, grounding and other protective measures during installation or daily use to reduce the possibility of damage.

Therefore, caution, attention to maintenance and upkeep are necessary when using an electromagnetic flowmeter in order to extend its service life and maintain its good working condition.

KOBOLD's new DUK series flow meters are used for measuring, monitoring, metering, and quantitative functions of low viscosity fluids. The working principle of this product is the difference in running time. It is based on the fact that ultrasound waves in a medium are affected by flow velocity. Two sensors installed relatively in the pipeline simultaneously function as transmitters and receivers of ultrasonic signals. If there is no fluid, then the running time of the two signals is the same. If the medium is flowing, the running time of the counter current signal is longer than that of the counter current signal. The running time difference is determined by the microprocessor and is proportional to the flow rate.
