Development trend and prospect of mass flowmeter - focus on microfluidic control technology

At present, mass flow meters account for a large proportion in China's imported instruments. Specifically, the installation of small-caliber gas mass flow meters is relatively large, and is generally applied in petrochemical and chemical test equipment, and also has a small amount of application in the production departments of medicine and food, although the quantity is small. , but with good prospects.
In recent years, gas mass flow meters of medium and small caliber have maintained a relatively fast development speed in China. At present, more than half of the mass flow meters installed in China are produced domestically, and the imported products are mainly concentrated in the products of Brooks, EPI and other companies. Because of the constraints on the calibration equipment, there are relatively few manufacturers of large-caliber gas mass flowmeters in China, which results in a large proportion of imports of such products, but has shown a downward trend in recent years.
As for the liquid mass flow meter, because of the complicated technology, the benefit cycle is long, and the progress is relatively slow. Although many scientific research departments have carried out the work of researching the product, the manufacturer has not yet scaled up and the production is limited. However, with the increasing demand for this product, the production capacity of domestic manufacturers has also increased, and the number of domestically produced products has also increased significantly. At present, China's liquid mass flowmeters are widely used in the measurement and control of petrochemicals, building materials and other fields.
However, in terms of the comprehensive performance of batch products, the gap between domestic and foreign is mainly reflected in the following points: First, there is a lack of consistency in raw material performance. For example, in the force flowmeter, there are differences in performance requirements of domestic raw materials, followed by Domestically, the level of production automation is relatively low.
For liquid mass flowmeters, due to the broad application prospects, it is necessary to strengthen the development and research of domestic liquid mass flowmeters. Although this production technology has great difficulty, in recent years, China has made a very big technological breakthrough in the production of liquid mass flow meters. Domestic products have caught up with foreign advanced products in terms of performance and technical indicators.
