The difference between the electromagnetic flowmeter domestic and imported
Electromagnetic flowmeter in the field of modern industry and medicine convenient food industries is the most widely used one of flow meters, noted the difference between domestic and imported electromagnetic flowmeter, you may is generally accepted that imports of high-end in domestic electromagnetic flowmeter, electromagnetic flowmeter must be in henan province in this article the SIKE measurement and control technology co., LTD. Introduction to the distinction between. Instrument development history has nearly 50 years, far more than the Chinese foreign instrument industry development, some imported electromagnetic flowmeter performance is better than domestic, such as Germany's Siemens, but some of the flow meter of domestic and imported no matter in which convenience has no difference.
First electromagnetic flow meter in the measurement accuracy, due to the comprehensive production abroad than domestic leading level, raw materials and processing technology were higher than the domestic level, material exquisite stringent, so on the precision of electromagnetic flowmeter is superior to domestic imports, but according to the requirement of the working condition of flowmeter can provide special 0.2% accuracy.
Zero drift, measuring instrument in use, the zero drift is normal, will have zero drift, but imported electromagnetic flowmeter than domestic small, generally does not affect the normal use.
Year of life, under the same conditions, the same use, the comprehensive performance advantage into the electromagnetic flowmeter and domestic life.
Price, imported electromagnetic flowmeter are three times more than domestic electromagnetic flowmeter, the choose and buy according to the requirements of accuracy, the actual situation to choose.
After-sales service, whether it's domestic or imported electromagnetic flowmeter, maintenance and after-sales service, has a domestic electromagnetic flow meter manufacturers in China, so the accuracy of the calibration reward, parts replacement is more convenient, and imports due to is the requirement of the principle of parts is quite troublesome, basically there is no way to replace parts.
On the work process, domestic electromagnetic flowmeter development and improvement for many years, craft was imported, due to the quality of and process and price determines the domestic meter technology coarse.
The gap between domestic electromagnetic flowmeter products and imports cause analysis has the following several aspects. Operating mechanism of enterprises is in the process of development, although can have what improvement on production, science and technology innovation ability needs to improve. Electromagnetic flowmeter production enterprise is what most small and medium-sized enterprises, and mostly not mastered advanced core technology, wear less fruits heart, also can't compete with foreign companies.
Overall production, study and research, such as not form a organic combination of system and policy, innovation achievements conversion rate is low, poor electromagnetic flowmeter industry technology application. Second, the absence of strong research support system. Instrument and meter industry many varieties, small batch, need long-term and unremitting. Electromagnetic flowmeter technology not only involves the wide range of disciplines, and only can find as soon as possible, using, integrated all sorts of new principles, new concepts, new technology, new material and new technology such as the latest scientific and technological achievements, to design and produce world-class products electromagnetic flowmeter. Talent shortage, nature affect the development of the industry. This is, of course, the gap between domestic electromagnetic flowmeter and imported products.
Along with the rapid development of oil and natural gas industry in China, the demand for oil, natural gas use steel tube expanding, prompting the rapid ascension electromagnetic flowmeter production technology and , the batch used in oil, natural gas, high-performance, high-quality, high value-added electromagnetic flowmeter has been completed and put into production line in our country at present, our country has all the world's most advanced rolling tube technology, the overall level of the domestic electromagnetic flowmeter is a vast improvement. Many electromagnetic flowmeter domestic enterprises to establish the well tube product line production line, the localization rate increased year by year, needed for the supercritical and ultra supercritical unit electromagnetic flowmeter and other varieties have been able to bulk supply.
Electromagnetic flowmeter industry, domestic construction of the advanced production line, seamless electromagnetic flowmeter rising proportion of special electromagnetic flowmeter production in our country, but some high-end products in variety and quality and quantity with the international level of imports is still some way, it also caused some businesses still rely on imports. Can say that in recent years, domestic electromagnetic flowmeter structure although improved substantially, but there is a certain difference and imported electromagnetic flowmeter.
