What are the characteristics of the outer casing of the electromagnetic flowmeter?

For any kind of flowmeter, in addition to a stable system, the outer casing is also a very important criterion. Many people choose the electromagnetic flowmeter to pay attention to whether the magnetic circuit system can uniformly generate DC or AC magnetic field. Pay attention to whether the measuring catheter can let the measured liquid pass normally without interference, pay attention to the signal of the electrode, etc., but ignore the importance of the outer casing. What requirements does the electromagnetic flowmeter have for the outer casing? Let's take a look at it briefly.

It should be said that most of the outer casings of electromagnetic flowmeters are made of ferromagnetic materials. Of course, such ferromagnetic materials should be said to be not ordinary ferromagnetic materials, because they also need certain requirements in the industry. It is guaranteed that it will not be disturbed by the external magnetic field, so that the entire flowmeter can operate normally and exert its relatively stable performance. Therefore, it is required to have a magnetic coil cover of the distribution system, so as to better ensure the entire flowmeter. Normal use.

Of course, the electromagnetic flowmeter is not only for the outer casing, it should be said that for every link of the entire device can be normal operation, there are many regulations in the industry, such as the lining must be electrically insulated lining, The converter should also be able to isolate the other interfering signals while ensuring the signal. It can be said that there are many requirements.
