Description of the characteristics of electromagnetic flowmeter measurement in the petroleum and chemical industry

Characteristics of electromagnetic flowmeter measurement in the petroleum and chemical industry: The petroleum and chemical industry is a large market for flow meters, with large demand and variety. Most types of flowmeters can find applications in the petrochemical and chemical industries. Object.
Flow measurement objects in the petrochemical and chemical industries Due to the diversity of the measured media, the measurement range is also extremely demanding, ranging from the measurement of small flows used by additives and small test devices to the measurement of large flows of feed gas flow, from the most common water. Vapor, air, gas, etc., to all kinds of chemical products and semi-finished products, as well as residues, liquid ammonia, liquid hydrocarbons and other objects with high difficulty in measurement, everything.
The petrochemical industry has strong financial strength and is an important market for high-end products with excellent quality and high price. In addition to some of the basic features described above, there are two distinct features below.
4 Most petrochemical and chemical enterprises have explosion-proof requirements. Even if the fluid to be tested is not a flammable or explosive substance, the whole area is a flammable and explosive place. Therefore, the instrument should be in accordance with the explosion-proof regulations when selecting the type.
2 is corrosive. There are many corrosive fluids to be tested, and some corrosion resistance problems must be considered when contacting the corrosive medium. In addition to the corrosion of the measured medium, there is atmospheric corrosion. For example, the rainwater in the chlor-alkali plant, the nitrogen fertilizer plant, and the sulfuric acid plant plant area has a certain corrosive effect on the exposed parts of the instrument. Therefore, it is necessary to consider the protection of the outdoor instrument to avoid premature damage.
