Difference between electromagnetic flowmeter and ordinary flowmeter
First, the principle is different: The principle of electromagnetism is tested by Faraday's electromagnetic induction principle. Because his principle is the principle of electromagnetism, Ken
Must consider his ability to resist electromagnetic interference, so their principle determines their own production process, not to prevent electricity
The magnetic interference coils, so that they will not be electromagnetic interference, so as to achieve product performance stability.
Second, the test medium is different: The electromagnetic flowmeter mainly tests the charged ionic liquid. If it is a liquid that is not taken, they have no way to test it.
For example, test oil, they can not test.
Third, the pressure loss: electromagnetic flowmeter because there is no moving parts, the fluid in the pipeline, is flowing from a pipe through the pipeline, did not
With any pressure loss, other flowmeters are not the same. They are all measured by a volumetric method, so they must produce.
Raw pressure loss.
Fourth, corrosive: electromagnetic flowmeter for corrosive liquids, can replace the electromagnetic flowmeter lining to match the corresponding medium, its
He can't flow meter, if you want to resist corrosion, they must change the overall material
Fifth, the cleanliness of the liquid: Electromagnetic flowmeter is mainly to test the liquid containing impurities, such as sewage, mud, sand, etc. can measure
Six, diameter: the diameter of the electromagnetic flowmeter can be DN2200
