Flow meter looks forward to the future

Current meter flow measurement's future

The innovation from mechanical flowmeter to electronic flowmeter is one of the most important development trends of flowmeter. Target flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, vortex flowmeter and V-cone Flowmeter (orifice flowmeter) work based on electrical principle, so as to avoid the moving parts that need to be replaced in the work of mechanical flowmeter. For the purpose of self inspection and self diagnosis, the flowmeter is introduced into the pipeline at the same time. Moreover, after the electronic flowmeter is combined with advanced communication technology, the control personnel can obtain the flow data and historical data of the production site remotely and in real time.

According to Frost & Sullivan's research, at present, about 89.0% of the flowmeters in the world use the mhart communication protocol, because the installation difficulty and operation requirements of the flowmeters using the mhart communication protocol are lower than those using the fieldbus protocol, and the introduction of the fieldbus system is also a great cost for users. However, with the continuous improvement of automation level of industry users, they hope to obtain more information from traffic measurement, such as diagnosis information and status detection. These data transmission needs to rely on Fieldbus support. Moreover, manufacturers such as Siemens and aimer are focusing on the flow measurement technology of fieldbus protocol. It is believed that this will promote the application prospect of fieldbus protocol flowmeter in various industries.

In addition, wireless technology flowmeter is gradually accepted by users. Fluid measurement in harsh environment is a good application space for wireless technology. However, it will take some time for users to fully accept and popularize wireless technology.
