Electromagnetic Flow Meter in the Industrial Brewing Process
Here we discuss the application of DN80 electromagnetic flowmeter in the beer production industry. Beer production (Brewing) is one of the most difficult processes in the food industry. In order to obtain high-quality beverages, the brewing process includes the Preparation of must, Boiling the must, Fermentation, Maturation, Filtration, and Bottling. Electromagnetic flow meters are an important process control instrument of brewing technology used in modern factories. Now we will talk about the application and characteristics of the electromagnetic flowmeter in the beer production industry.
Introduction of Beer Production Industry
According to the 2021 annual output data report of the craft beer industry released by the International Brewers Association, in 2021, the retail sales of the entire beer market will be about 26.9 billion dollars, accounting for 26.8% of the market share, an increase of 21% over 2020. Breweries provided more than 172643 direct jobs, an increase of 25% over 2020. This shows the importance of beer making industry. The process control instrument plays a vital role in the beer production process. Although the scale and management of these enterprises vary greatly, the degree of automation of the production equipment used is constantly improving, and the intelligent DN80 electromagnetic flowmeter, especially the sanitary DN80 electromagnetic flowmeter, is being used more and more widely. DN80 electromagnetic flowmeter is used in processes such as the measurement of crushing water, the measurement of washing water, the measurement of filtered wort, the measurement of cold wort, the measurement of sake, and the measurement of filling wine.
Sanitary (Food-grade) DN80 Electromagnetic Flowmeter
The sanitary DN80 electromagnetic flowmeter is used in the beer-filling production line to achieve quantitative filling at the same time. An electronic valve filling machine equipped with a sanitary electromagnetic induction flowmeter is used, which is a dynamic metering quantitative form. The electromagnetic flowmeter is used for the dynamic metering of the liquid flowing through the valve.
According to Faraday's electromagnetic induction principle, that is, when a conductor passes through a magnetic field, an induced electromotive force will be generated. The flowing liquid medium represents a moving conductor, and the induced current is proportional to the flow speed. After a pair of electrodes is input into the metering amplifier, the flow rate can be accurately obtained by calculating the cross-sectional area and flow rate of the fluid, and the quantitative accuracy is up to five thousandths. Therefore, the DN80 electromagnetic flowmeter plays an important role in the measurement process of beer brewing, with the advantages of low failure rate and high measurement accuracy.
Many people will wonder why it is a DN80 electromagnetic flowmeter. Doesn't DN80 mean pipe diameter? Can't other pipe diameters work? Of course not. DN80 is just one of them, but it is also the most commonly used pipe diameter in the beer industry. So we usually ask customers about the electromagnetic flowmeter used in the beer industry, which will basically be useful for the DN80 electromagnetic flowmeter, which is related to the equipment produced by beer enterprises.
The Characteristics of the DN80 Electromagnetic Flowmeter
The following describes the characteristics of the DN80 electromagnetic flowmeter:
1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity (no less than 5us).
2. There are no flow-blocking parts and pressure loss in the measuring pipe, and the requirements for a straight pipe section are low. It has unique adaptability for slurry measurement.
3. Electrode and lining materials shall be selected reasonably, which means good corrosion resistance and wear resistance.
4. Full digital quantity, strong anti-interference ability, reliable measurement, high accuracy, and flow measurement range of 10:1
5. The 16-bit embedded microprocessor is adopted, with fast operation speed and high accuracy. The programmable frequency low-frequency rectangular wave sharpens the magnetic field, improving the stability of flow measurement and low power consumption.
6. SMD devices and surface mount (SMT) technology are adopted, with high circuit reliability.
7. There are no movable parts or flow-blocking parts in the pipeline, and there is almost no additional pressure loss in the measurement.
8. The measuring range can be modified online according to the actual needs of users on site.
9. The measurement results are independent of the flow velocity distribution, fluid pressure, temperature, density, viscosity, and other physical parameters.
10. High definition backlight LCD display, English menu operation, easy to use, simple to operate, easy to learn and understand.
11. It has RS485, RS232, Hart, Modbus Profibus DP, and other digital communication signal outputs (optional).
12. It has self-inspection and self-diagnosis functions.
13. Hourly total volume recording function, which records the total volume of flow in hours, applicable to time-sharing measurement system (optional).
14. There are three integrators inside which can respectively display the positive accumulators, the reverse accumulators, and the difference accumulators. There is a power down clock inside which can record the power down time 16 times.
