代表了目前市场最高技术水平 Vortex flowmeter represents the highest technology level in the market
1: Market scale of flow meters:
Flow meter is a kind of meter whose performance strongly depends on changes in the use conditions. In the actual measurement environment on the spot, the accuracy of the meter is affected by various factors such as the stability of the measurement medium, pressure, and bubble content. Therefore, due to the diversity of measurement media, the diversity of flow meters is also determined. But on the whole, from the measurement principle, it can be divided into three types: area type (speed type), volume type and mass type. From the product form, the main flow products currently include more than 10 ways such as differential pressure, electromagnetic, vortex, mass, ultrasonic, volume, rotor and so on.
2: Market growth of flow meters:
According to MIR research, despite the economic downturn in the fourth quarter of 2008, for the full year of 2008, the flow meter industry still maintained a growth of 8.4%. The order value increased from RMB 3.1 billion in 2007 to RMB 3.4 billion in 2008. Among them, the growth rate of traditional meters (throttle, volume, turbine, rotor flow meters, etc.) has slowed down significantly, and the growth rate in 2008 was 4.8%; while the new meters (electromagnetic, ultrasonic, vortex, Coriolis mass flow meters) in 2008 The average growth rate is 10%, especially for mass flow meters and vortex flowmeters. Judging from the current market development, the growth rate of traditional instruments has slowed down significantly, such as low-end throttling devices, lower technical thresholds, many domestic manufacturers can produce, fierce price competition, resulting in weak sales growth. The ultrasonic flowmeter market has grown faster in recent years. Compared with the throttle device, the range ratio of the turbine can reach 10: 1, which is more accurate. It is still used by small and medium customers in trade settlement. The electromagnetic flowmeter is the fastest-growing one. Fast instruments, because there are no intermediate parts, and at the same time easy to maintain, are widely used. With the development of flow meter technology, it is a general development trend that new meters replace traditional meters in many fields, but the process will be long.
3: Market Share of Flow Meters
At present, several major multi-product suppliers in the flow meter market, such as EMERSON, YOKOGAWA, E + H, and KROHNE, all appear in the rankings. In different sub-fields, they each have their advantages. A large number of private enterprises have emerged in China's ever-growing traffic instrument market. Although it is not the main force in the market at present, it can also be seen that China's domestic instrument market is developing rapidly.
A. Vortex Flowmeter Market
技术以ABB、Krohne和横河三家厂商为主要代表。 At present, the domestic vortex flowmeter technology is mainly represented by three manufacturers: ABB, Krohne and Yokogawa. Domestic manufacturers' technology is generally derived from ABB technology. Krohne low-frequency rectangular wave excitation type vortex flowmeters are mainly large-diameter products and are widely used in the water industry. Yokogawa's dual-frequency excitation technology, especially for small diameter products below 100MM, has a high share in the paper industry. In 2008, the overall market size of vortex flowmeters was 730 million. The top three KROHNE, YOKOGAWA, and E + H accounted for 45% of the market, and their market shares exceeded 10%. Although the performance is less than 10%, it is growing rapidly. Other market shares are less than 5%, but Siemens' growth in the process industry in recent years should not be underestimated.
B. Vortex Flowmeter Market
Vortex flowmeter technically, Krohne's vortex flowmeter represents the highest technology level in the market, but due to the high price level. Intelligent vortex flowmeter is a new type of internationally advanced flowmeter which is successfully developed based on the principle of Carmen vortex street. It is the most ideal substitute for orifice flowmeter.
Flow meter applications
1.Steam and saturated steam flow measurement
2.Steam boiler monitoring
3.Compressor air monitoring
4.Measure the amount of compressed air system
5.Measure industrial gas consumption
6.SIP and CIP processing in food, beverage and pharmaceutical industries
特点 Features of Intelligent Vortex Flowmeter
1. Simple and firm structure, no moving parts, high reliability, and very reliable long-term operation.
2. Within a certain Reynolds number range, the output signal frequency is not affected by the fluid physical properties and composition changes. The meter coefficient is only related to the shape and size of the vortex generator. No compensation is required when measuring the fluid volume flow. There is no need to recalibrate the meter factor.
3. Simple installation and convenient maintenance.
3, the detection sensor does not directly contact the measured medium, stable performance and long life.
4. The output is a pulse signal proportional to the flow rate, no zero drift, and high accuracy.
5. Wide measuring range, range ratio can reach 1:10.
6. The pressure loss is small, the operating cost is low, and it is more energy-saving.
7, a wide range of applications, the flow of steam, gas, liquid can be measured
