A Linked Industrial Flow Accurate Metering Method

Abstract

A linkage type industrial flow precision measurement method, which solves the problem that in the traditional flow measurement process, the flowmeter is only an isolated device for fluid measurement, without interconnection and interaction with the upstream and downstream processes and surrounding related measurement equipment, resulting in a significant increase in the measurement accuracy of the flowmeter. drop problem. This metering method analyzes the existing flow metering method based on a process-based algorithm, so that the flowmeter can compare the process with the production or operation of the upstream flowing medium closest to the flowmeter during the metering process, and then through the automatic flowmeter in the flowmeter The calibration function calibrates the flow results; then, communicates and interconnects the existing flowmeter with the upstream flowmeter, and performs self-correction; moreover, the shortage of straight pipe sections in the industrial field is considered during the measurement process. The method can be interconnected with other upstream and downstream metering equipment, which can improve the accuracy of industrial flow metering, optimize upstream and downstream production processes, reduce production costs, and improve the level of industrial automation.

Problems solved by technology

[0002] At present, although there are many types and different principles of industrial flowmeters, they all have a common feature, that is, during the flow measurement process, the data can only be read through the isolated device of the flowmeter installed on the pipeline. And transmit the data to the industrial control system through secondary meters, flow computers and other equipment

However, because the flowmeter cannot be calibrated for large pipe diameter real flow and various special media and working conditions, there are errors or even deviations in the actual measurement process of the flowmeter; will increase further

At the same time, due to the fluctuation adjustment of the upstream and downstream processes and the insufficient length of the straight pipe section on site, the working conditions used by the flowmeter often change, and the flowmeter is not in its original design during operation. Therefore, the measurement accuracy of the flowmeter is greatly reduced, which seriously affects the accuracy of the entire industrial flow measurement and is not conducive to the development of industrial automation.
