Summarize the future technological development of flowmeter manufacturers' products - focus on microfluidic control technology

1. Electromagnetic flowmeter: From the perspective of the electromagnetic flowmeter itself, the electromagnetic flowmeter is a sophisticated commodity. Following the development of skills in recent years, on the one hand, the electromagnetic flowmeter transmitter is intelligent, and the converter has increased the functions of self-determination and self-calibration. Then complete some online self-diagnosis functions, reduce the maintenance workload of the electromagnetic flowmeter, and replace the traditional offline inspection method with an online inspection. Now both Krohne and ABB are implementing this concept of online self-diagnosis. The on-line inspection methods of electromagnetic flowmeters are becoming increasingly sophisticated from birth to use, but it will take some time to implement them in various occupations across the country. Its greatest difficulty lies in the use of electromagnetic flowmeters as measuring instruments. Its on-line inspection standards have been recognized by the National Skills Supervision Department and various professional associations.

2. Vortex Flowmeters: The biggest question about the development of vortex flowmeters is how to resist the noise and oscillation problems that are used in practical production. The vortex flowmeter is still a developing flowmeter, regardless of its theoretical foundation or practical experience. In the next few years, the skills of vortex flowmeters will continue to be sophisticated, the user's affordability and skill level will gradually increase, and vortex flowmeters will gradually be used.

3. Mass flowmeters: Unlike electromagnetic and vortex flowmeters, mass flowmeters have a higher skill threshold. The biggest obstacle to widening the use of mass flow meters is the quotation. In the decades since the development of quality drift meters, local suppliers have not always grasped the high-end mass flow meter production skills in detail. Therefore, the quotation of mass flowmeters remains high, besides the extensive application in petroleum and petrochemical occupations, it is less used in other occupations because of quotation constraints. Now mainstream foreign mainstream mass flow meter suppliers have also seen such market demand and started to implement low-end mass flow meter products in the market. From the point of view of the mass flow metering technology, the mass flowmeter has a larger and larger diameter and can be used on various large-diameter pipes.
