1. Coriolis Mass Flowmeter (CMF)
The foreign CMF has developed more than 30 series. The development of each series is focused on the technical aspects: the design innovation of the flow detection and measuring tube structure; the improvement of the zero point stability and accuracy of the instrument; the increase of the deflection of the measuring tube to increase the sensitivity; and the improvement of the measurement tube stress Distribution, reduce fatigue damage, strengthen anti-vibration interference capabilities.
2, electromagnetic flowmeter (EMF)
Since EMF entered the industrial application in the early 1950s, the use of the field has been expanding. Since the late 1980s, it has accounted for 16% to 20% of the sales amount of flow meters in various countries.
China's rapid development in recent years, 1994 sales estimated at 6500 to 7500 units. In China, ENFs with a maximum diameter of 2 to 6 m have been produced, and there are equipment capabilities with a real-life calibration caliber of 3 m.
3, vortex street flowmeter (USF)
USF entered industrial applications in the late 1960s, and it accounted for 4% to 6% of the country's flow meter sales since the late 1980s. In 1992, the estimated worldwide sales volume was 3.548 million units, and domestic products were estimated at 8,000 to 9,000 units during the same period.
