Abstract

The invention discloses a measurement modular structure for a natural gas extraction process. The measurement modular structure for the natural gas extraction process comprises a DSP chip and an A / D conversion module connected to the signal input end of the DSP chip, and further comprises an SDRAM connected with the DSP chip, a FLASH module and a clock chip, wherein the DSP chip is further connected with a keyboard and a display screen. The measurement modular structure is simple, is convenient for realizing the real-time flow feedback of a condensate natural gas and reflecting the change of the flow along with the time in the feedback information, and is good for the accuracy of the flow statistics of the condensate natural gas.

Description

technical field [0001] The invention relates to the field of fluid conveying pipe fittings, in particular to a metering module structure used in the natural gas exploitation process. Background technique [0002] Electronic monitoring equipment is widely used in fluid delivery pipeline systems. Compared with mechanical metering equipment, it can facilitate remote transmission, small size, and easy equipment maintenance. It is widely used in people's daily life and industrial production. : Such as urban tap water, natural gas pipeline network system; industrial fluid transmission pipeline system, etc. [0003] During the exploitation of natural gas fields, with the continuous increase of the production period, the content of impurities in the output of gas wells will gradually increase. Usually the above impurities are condensed liquid hydrocarbons and water. Such natural gas is called condensed natural gas. The metering method of this kind of natural gas in the prior art is...
