流量计与DCS匹配问题研究

Research on the Matching of Flowmeter and DCS

众所周知,质量流量计是目前测量最准确的流量计量仪表,不过在日常应用中,我们发现质量流量计的流量累计数与远传到DCS上的流量累计数匹配研究。流量计校准装置无论是气装置还是液装置,其功能和基本原理基本相同,但受到技术条件和资金的限制。过程控制的现代化、自动化尚有大发展要做流量计,装置要先行,没有值得信任的校准装置,高准确度的流量计就成了空中楼阁。由此可见,大力发展高精度校准装置对于流量计产业的重要性。

As everyone knows, the flowmeter is a flow meter is currently the most accurate measurement, but in everyday applications, we find that the mass flow rate and the cumulative number of remote DCS traffic on the cumulative number of matching. Flow meter calibration device, whether it is gas or liquid device, its functions and basic principles are basically the same, but subject to technical conditions and funding constraints. The modernization of the process control, automation, there is still a big development to do the flowmeter, the device to go ahead, there is no trusted calibration device, high accuracy of the flowmcter became a castle in the air. It can be seen that the importance of the development of high precision calibration device for flowmeter industry.
