1. According to Flowresearch's online survey in foreign markets, the average annual growth rate (CAGR) of the world market for flow meters has reached 2.6%, and sales have grown from 3.1 billion U.S. dollars in 2002. By the end of 2007, US$3.5 billion, of which traditional instruments (throttle, volume, turbines, rotor flowmeters, etc.) were negative growth, CAGR was -2.2%, from US$1.643 billion in 2002 (53% of the total) to 2007 The annual growth rate of new instruments (electromagnetic, ultrasonic, Coriolis, etc.) averaged 6.2%, from 1.457 billion U.S. dollars in 2002 to 2.019 billion U.S. dollars in 2007, of which 1.505 billion U.S. dollars (43%) are annual. The annual growth rate and sales volume of electromagnetic, ultrasonic and Coriolis flowmeters are shown in Table 1. The electromagnetic flowmeter's CAGR is less than 2% due to its large base and mature technology.
The survey believes that turbine flowmeters are commonly used in many countries in the world to measure gases or liquids with low viscosity. Due to the rotating parts in the meters, the maintenance workload is large. The CAGR for the past 5 years is -3.2%, and the sales amount is from 2002. The 410 million U.S. dollars fell to 348 million U.S. dollars in 2007. Experts believe that although ultrasound has been growing aggressively in recent years, turbines are much cheaper than ultrasound and have price advantages. Compared with throttling devices, the range ratio can be as high as 10:1, and it is more accurate. In trade settlement, it is still small and medium-sized. Customers are happy to choose. Volumetric flowmeters are non-velocity instruments. Installation requires no straight pipe sections. Accuracy can generally reach ±0.5%, but it is cumbersome. The caliber is generally less than 0.2m. In the past five years, sales fell from 520 million U.S. dollars in 2002 to 452 million U.S. dollars in 2007, and the CAGR was -2.7%. Experts believe that new instruments replace conventional instruments in many fields and are an overall development trend, but the process will be long.
2. Domestic market According to statistics, in the domestic automation instrument market in 2005, the annual sales flow meter expressed 2.3 billion yuan; the pressure transmitter is about 1.8 billion yuan (of which about 500 million yuan is the differential pressure transmitter and difference Pressure meter matching); temperature instrument 1.2 billion; level, level instrument 1 billion. From the point of view of the type of flow meter, because the throttling device is relatively heavy and the technical content is relatively low, foreign manufacturers have not basically involved in the Chinese market for this type of product. The selection of such instruments in China's projects is mainly based on domestic products, and the annual sales volume. Not less than 200,000 units, about 600 million yuan or more.
China's efforts to develop and develop flow meters have a large gap with foreign countries and are more satisfied with imitation. This issue can be seen from the well-known exhibition MICONEX2006. At the exhibition, Chinese and foreign manufacturers exhibited a total of 297 flow meters with more than 10 principles. The frequency of the exhibition was listed in Table 2. As can be seen from Table 2, out of the 16 items classified, 204 manufacturers exhibited the first 6 items totaling 69% of the total, indicating that they are the focus of current Chinese and foreign instrument manufacturers, and the Coriolis flowmeters are exhibited abroad. There are 17 companies accounting for 68% of the total, and only 8 in the country. Does it mean that the domestic measurement of this kind of meter with accurate mass flow rate is insufficient in China; while the internal cone flowmeter, the number of domestic exhibitors reaches 30, accounting for 91% of the total; there are only 3 foreign countries. Is the domestic market overheated?
• Electromagnetic flow meters are still hot spots in flow meters and they are in the first place. China's major instrument manufacturers have listed it as a major product. According to the assessment of the US ARC Consulting Company, due to the special emphasis on environmental protection in recent years, China has depended on the rapid development of Sheung Shui/Sewer, metallurgy, mining, pulp and pharmaceutical industries. In the next five years, the electromagnetic flowmeter in China's CAGR will reach 10.7%. In 2003, the increase from 380 million yuan to 640 million yuan in 2008.
Ultrasonic flowmeter has many advantages, such as accuracy, pressure loss and small, especially suitable for the trade measurement of precious fluids. Both at home and abroad pay more attention to it, but domestic exhibits mostly measure fluids, although there are several methods to measure gas. There are still some problems in the field, especially for trade settlement.
· Thermoelectric flowmeters have many exhibits. Because it can measure mass flow and have high sensitivity, it is highly valued by the industry. However, its plug-in type can only measure dry, pure gas, and the accuracy is not advertised by manufacturers. It's so high. It's still a long way from practicality.
