Introduction to product and technology trends for flow meters

1. Electromagnetic flowmeter: From the perspective of the electromagnetic flowmeter itself, the electromagnetic flowmeter is a mature product. With the development of technology in recent years, on the one hand, the electromagnetic flowmeter transmitter is intelligent, and the inverter has added functions such as self-diagnosis and self-calibration. Thereby, some online self-diagnosis functions are realized, the maintenance workload of the electromagnetic flowmeter is reduced, and the traditional offline inspection method is replaced by the online inspection. Both Krohne and ABB are promoting this concept of online self-diagnosis. The online inspection method of electromagnetic flowmeter is becoming more and more mature from birth to application, but it will take some time to promote it in various industries across the country. The biggest difficulty lies in the electromagnetic flowmeter as a measuring instrument, and its online inspection specification needs to be recognized by the national technical supervision department and relevant industry associations.
 
    2. Vortex flowmeter: The biggest problem in the development of vortex flowmeter technology is how to resist the noise and vibration problems in actual production. Vortex flowmeters are still developing flowmeters, regardless of their theoretical basis or practical experience. In the next few years, as the technology of vortex flowmeters continues to mature, the acceptance level and technical level of users will gradually increase, and the vortex flowmeter will gradually be maturely applied.
 
    3. Mass flow meter: Unlike electromagnetic and vortex flowmeters, the mass flowmeter technology has a higher threshold. The biggest obstacle to the development of mass flow meters is the price issue. In the decades since the development of mass wanderers, local suppliers have not yet mastered the high-end mass flowmeter production technology. Therefore, the price of mass flow meters is high, except that it is widely used in the petroleum and petrochemical industry, and it is less used in other industries due to price restrictions. At present, the mainstream mainstream mass flowmeter suppliers in foreign countries have also seen such market demand, and have begun to promote low-end mass flowmeter products in the market. From the perspective of mass flowmeter technology, the mass flowmeter has a larger and larger diameter and can be used on various large diameter pipes.
