Pressure Cooker is divided into traditional pressure cooker with external heat source and electric pressure cooker. In recent years, the rise of electric pressure cooker has surpassed the popularity of traditional pressure cooker. Advantages of electric pressure cooker: 1. There are ready-made function keys to select. After pressing, don't worry about it. Automatic pressurization, power failure and pressure relief. The function is stupid. 2. It has additional functions such as timing. It is scheduled at night and cooked the next morning. It is convenient for office workers to sleep in. The disadvantage is that the electric pressure cooker contains electronic components, and the failure rate is higher than that of the traditional pressure cooker. In addition to timing, the function of electric pressure cooker can be achieved by traditional pressure cooker. But you need to watch yourself. Brands: mainly domestic brands, Ewong,KingDao, Midea, Jiuyang joyong, Supor, Pentium Povos and other domestic small household appliance brands take electric pressure cooker as their main products, with many models. Prices range from a few hundred dollars to a thousand dollars. The basic functions are the same. The difference is capacity, material, additional functions, etc. Pressure cooker is a high-pressure vessel. Quality problem is very important. Don't buy miscellaneous brands. The above are domestic regular brands with large scale and good reputation. In addition, be careful not to buy aluminum alloy, but stainless steel. Because stainless steel is much stronger, it is safer. In particular, 18 / 10 medical stainless steel is the best. This stainless steel is food safe and has the strongest rust and corrosion resistance

In 2008, the market size of global flowmeters reached 2.83 billion U.S. dollars, an increase of 3.9% over 2007. It is predicted that by 2013, the global flow meter market will reach 3.48 billion US dollars. The compound annual growth rate for 2008-2013 will reach 4.2%. The market size of flowmeters has a good momentum of growth, but not all companies have development opportunities.
In the world, the main manufacturers of flowmeters include ABB, Emerson, EndressHauser or EH, Krohne, Siemens, Yokogawa. , as well as General Electric, Honeywell, Invensys, and Yamatake. The market concentration of flowmeters is relatively high. The top three vendors, Emerson, E+H, and ABB account for nearly 50% of the market. In the segmented market, these large companies will take up a large "cake" with their technological advantage. However, due to the low threshold of the domestic flow meter industry, the quality of flow meter products varies greatly, which leads to companies with weak technical forces to face enormous competitive pressure.
Domestic small and medium-sized flowmeter manufacturers want to be able to assign “a glass of cake†in the market segment, so they need to increase their investment in technology and pay attention to product quality and after-sales service. 
Introduction: Although today's flowmeters have matured, their types are still very numerous. There is no flow meter that is suitable for any occasion. With the development of industry, the accuracy and range of flow measurement are increasingly demanding. In order to adapt to a variety of uses, various types of flow meters have come out one after another, and the flow meter industry is also facing opportunities and challenges in the market segmentation.
