Comprehensive analysis of the technical level of the scale of vortex flowmeter

Abstract: the comprehensive analysis of the technical level of the vortex flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: the instrumentation industry as a whole comprehensive technical level has reached international level of the mid - 80 - s, microelectronics and computer technology widely used in the instrumentation products, about 15% of the product realization intellectualization, reached the international level in the 90 s. 30% of the product realization. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a comprehensive analysis of the technical level of the scale of vortex flowmeter are details. Instrumentation industry as a whole comprehensive technical level has reached international level of the mid - 80 - s, microelectronics and computer technology widely used in the instrumentation products, about 15% of the product realization intellectualization, reached the international level in the 90 s; 30% of the product realization digitization, reached the international level in the late 80 s. This paper mainly introduces the domestic current situation of the development of vortex flowmeter. Zui young group are vortex flowmeter in flow meter, but its rapid development, now has become a general class of flowmeter. According to the frequency of vortex flowmeter detection methods can be divided into: stress, strain type, capacitance type, thermal, vibration postures, photoelectric, ultrasonic type, etc. Zui young group are vortex flowmeter in flow meter, but its rapid development, now has become a general class of flowmeter. Instrumentation industry as a whole comprehensive technical level has reached international level of the mid - 80 - s, microelectronics and computer technology widely used in the instrumentation products, about 15% of the product realization intellectualization, reached the international level in the 90 s; 30% of the product realization digitization, reached the international level in the late 80 s. Comprehensive service ability significantly to ask: can carry on 300000, so this paper mainly introduces the domestic current situation of the development of vortex flowmeter. Domestic current situation of the development of vortex flowmeter, vortex flowmeter is placed in the fluid a streamlined swim body vortex, fluid in the event of a body on both sides of the separation alternately releases two series of rules of staggered vortex of the instrument. The advantages of domestic vortex street flowmeter: ( 1) Simple structure and firm; （ 2) Apply fluid variety; （ 3) High precision; （ 4) Wide range of degrees; （ 5) Loss of pressure is small. Disadvantages: (domestic vortex flowmeter 1) Not suitable for low Reynolds number measurement; （ 2) Need a long straight section; （ 3) Instrument coefficient is low, Compared with the turbine meter) （ 4) Instrument in the pulsating flow, multiphase flow is still lack of experience. Domestic current situation of the development of vortex flowmeter after half a century of development, the reliability research and application has become a throughout each discipline engineering disciplines, from all walks of life to have from the reliability of electronic product development to the reliability of mechanical and electronic products, from hardware to software reliability, the reliability of the development from attaches great importance to the reliability statistical test to emphasis on reliability engineering test, through the environmental stress screening and enhanced reliability test to expose product failure, improve the reliability of products. According to the institute of mechanical industry instrumentation comprehensive technical and economic professor town of stone mountain, in the practical use, the user's response is also the main product is stable and reliable. Reliability research and application in instrument and meter industry has a long history and glorious traditions. In 1981, the original state administration of instrument and meter industry DDZ - is put forward Type 2 temperature transmitter, vortex flowmeter is typical of exploratory experiment study, to carry out the reliability appraisal test work, grope for the application of reliability methods, ways and effects. Through the improvement, temperature transmitter reliability index increased 1. 6 times, regulator to improve 2. Nine times. In 1986 ~ 1991, the original machinery industry has released & other; Instrumentation deadline throughout the inspection reliability &; Notice of instrument and meter of 11 professional category of more than 200 kinds of products into the ministerial appraisal. Through practice of this phase, forming instrument reliability method, working procedures, technical specifications and so on a series of technical documents, for the research of reliability, test and examining the created conditions. In the 1990 s, instrument and meter main re-innovation attract to a new way, manufacturing and technology without the design of the product of the introduction of technology, the reliability of the result in consciousness. Practice and promote the reliability of the era of planned economy is out of date, both at home and abroad new reliability concept, methods and tools development soon, cause with foreign gap is narrowing quickly widening again. Reported in 2008, the vortex street flowmeter wen wrote further implement the scientific concept of development is discussed in the pointed out that at present the development of equipment manufacturing industry lags behind, and product reliability is poor, weak complete sets of problem is very outstanding. Must change this situation as soon as possible, improve the ability of research and development of major equipment design, manufacturing and integration ability, the development of major equipment required equipment, high technology and equipment and high technology industries, promote the greening of the equipment manufacturing industry, informationization and localization. In September 2008, the domestic current situation of the development of vortex flowmeter are unanimously passed at the Chinese academy of instrument management & other; Suggestions for set up reliability national laboratory instruments & throughout; That instrument reliability work urgently needs the government's policy guidance and strong support. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

The increasing consumption demand in key segments such as tuning fork liquid density meter, endress hauser ultrasonic flow meter and endress hauser coriolis mass flow meter have been driving the sales of and its derivatives worldwide.
