Development Status of Flow Meters at Home and Abroad

Abstract: The information on the development status of flow meters at home and abroad is provided by the excellent manufacturers of flow meters and flow meters. 1. Foreign market According to the online survey of Flowresearch, in the past five years, the international economy is generally not very prosperous. The average annual growth rate (CAGR) of the flow instrument world market still reached 2.6%, and the sales increased from 3.1 billion US dollars in 2002. $3.5 billion by 2007, of which. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the development status of flowmeters at home and abroad. 1. Foreign market According to the online survey of Flowresearch, in the past five years, the international economy is generally not very prosperous. The average annual growth rate (CAGR) of the flow instrument world market still reached 2.6%, and the sales increased from 3.1 billion US dollars in 2002. $3.5 billion in 2007, of which traditional instruments (throttle, volume, turbine, rotameter, etc.) had a negative growth and a CAGR of -2.2%, from $1.643 billion in 2002 (53% of the total) to 2007 The annual growth rate of new instruments (electromagnetic, ultrasonic, Coriolis flowmeter, etc.) averaged 6.2%, from $1.457 billion in 2002 to $2.019 billion in 2007, of which , The annual growth rate and sales of electromagnetic, ultrasonic and Coriolis flowmeters are shown in Table 1. The CAGR of electromagnetic flowmeters is less than 2%, because the base is already large and the technology is relatively mature. The survey believes that turbine flowmeters are often used in many countries in the world to measure gases or liquids with low viscosity. Due to the rotating parts in the instrument and the heavy maintenance workload, the CAGR in the past five years is -3.2%, and the sales volume has increased from 2002. $410 million fell to $348 million in 2007. Experts believe that although the growth momentum of ultrasound has been aggressive in recent years, the turbine is much cheaper than ultrasound and has a price advantage; compared with the throttling device, the range ratio can reach 10:1, and it is more accurate. In terms of trade settlement, it is still small and medium. Customers are happy to choose. The volumetric flow meter is a non-velocity meter, and there is no requirement for straight pipe sections to be installed, and the accuracy can generally reach±0.5%, but bulkier. The diameter is generally less than 0.2m. In the past 5 years, sales fell from $520 million in 2002 to $452 million in 2007, with a CAGR of -2.7%. Experts believe that it is a general development trend that new instruments will replace traditional instruments in many fields, but the process will be long. 2. Domestic market According to statistics, in the domestic automation instrument market in 2005, the annual sales of flow meters were 2.3 billion yuan; pressure transmitters were about 1.8 billion yuan (of which about 500 million yuan of differential pressure transmitters pressure flowmeter); 1.2 billion yuan for temperature instruments; 1 billion yuan for level and liquid level instruments. From the perspective of the type of flow meter, due to the relatively cumbersome throttling device and relatively low technical content, foreign manufacturers have basically not set foot in the Chinese market for such products. The selection of such meters in my country's projects is also mainly based on domestic products. No less than 200,000 units, about 600 million yuan or more. There is a big gap between my country's research and development of flow instruments and foreign countries, and most of them are satisfied with imitation. This problem can be seen from the well-known exhibition MICONEX2006. Participating in this exhibition, Chinese and foreign manufacturers exhibited a total of 297 flow meters with more than 10 principles, which are listed in Table 2 according to the frequency of exhibition. It can be seen from Table 2 that among the 16 items classified, a total of 204 manufacturers exhibited the first 6 exhibits, accounting for 69% of the total, indicating that they are the hotspots of current Chinese and foreign instrument manufacturers, and among them Coriolis flowmeters, foreign exhibitors There are 17 companies accounting for 68% of the total, and only 8 companies in China. Does it indicate that the domestic attention is not enough for this kind of accurate mass flow meter? For inner cone flowmeters, 30 domestic exhibitors accounted for 91% of the total; only 3 foreign companies participated. , Is the domestic market overheated?·Electromagnetic flowmeters are still the hot spot in flow meters, ranking first. my country's major instrument factories have listed it as the main product. According to the assessment of the American ARC consulting company, China has paid special attention to environmental protection in recent years, relying on the rapid development of water supply/sewage, metallurgy, mining, pulp, and pharmaceutical industries. In the next five years, the CAGR of electromagnetic flowmeters in my country will reach 10.7%. 380 million in 2003 increased to 640 million in 2008.·Ultrasonic flowmeters have many advantages, such as accuracy, small pressure loss, especially suitable for trade measurement of precious fluids, which are paid more attention at home and abroad, but most of the domestic exhibits are for measuring liquids, although there are also a few for measuring gases, which are applied to the scene. , especially for trade settlement, there are still some problems.·There are also many exhibits of thermoelectric flowmeter. Because it can measure mass flow and has high sensitivity, it is valued by the industry. However, its plug-in form can only measure dry and pure gas, and its accuracy is not what the manufacturer advertises. So high, it will take time to be practical. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Development Status of Flow Meters at Home and Abroad'

Every day of the year, there is some city or town in the world that is changing over to for insertion ultrasonic flow meter.
