Embodiment 1

[0023] Such as figure 1 Shown, a kind of metering method of natural gas comprises the following steps:

[0024] (1), data collection: the natural gas is sequentially passed through the natural gas metering device with the first flow rate changer and the second flow rate changer, and n groups of flow m passing through the first flow rate changer are obtained 11 、m 12 、m 13 …m 1n and n sets of flow m passing through the second flow transmission 21 、m 22 、m 23 …m 2n ;

[0025] (2), weighted average processing data: obtain the average value M1 of the flow through the first flow rate change-speed member and the average value M2 of the flow through the second flow rate changer by weighted average, finally obtain flow value M=1 / 2 (M1+M2).

[0026] Among them, the natural gas metering device includes a pipeline for natural gas to pass through, and the first pipeline section, the second pipeline section 4, the third pipeline section, the fourth pipeline section, and the fifth ...

Abstract

The invention discloses a method for metering natural gas. The method for metering the natural gas comprises the following steps: (1) collecting data: making the natural gas pass through a natural gasmetering device with a first flow speed changing member and a second flow speed changing member sequentially, so as to obtain n sets of flow m<11>, m<12>, m<13>...m<1n> passing through the first flowspeed changing member and n sets of flow m<21>, m<22>, m<23>...m<2n> passing through the second flow speed changing member; and (2) processing the data in a weighted average manner: obtaining an average value M1 of the flow passing through the first flow speed changing member and an average value M2 of the flow passing through the second flow speed changing member through weighted averaging, andfinally obtaining the flow value M = 1 / 2 (M1 + M2). The method for metering the natural gas can reduce the influence of environmental factors on the metering and improve the metering accuracy.

Description

technical field [0001] The invention relates to the technical field of natural gas flow metering, in particular to a natural gas metering method. Background technique [0002] Natural gas is a mixture dominated by hydrocarbons. Hydrocarbons in natural gas include methane, ethane, propane, butane, pentane, and hexane. In addition to hydrocarbons, it also contains carbon dioxide. [0003] Natural gas metering has an accuracy problem. The measurement results of different test locations may be affected by environmental conditions, resulting in deviations in the measurement results. Therefore, it is necessary to improve the accuracy of the measurement results. Contents of the invention [0004] The object of the present invention is to provide a natural gas metering method, and the device can improve the accuracy of metering results. [0005] The present invention realizes through following technical scheme: [0006] A method for measuring natural gas, comprising the follow...
