Abstract

The invention discloses a natural gas flow measuring device for a water-containing natural gas transmission pipeline; the natural gas flow measuring device is provided with a measuring pipe, a first differential pressure transmitter, a flow totalizer and a second differential pressure transmitter, wherein the measuring pipe is provided with a Pitotbar flow sensor; a top pressure guide pipe and a bottom pressure guide pipe which are communicated with the interior of the measuring pipe are symmetrically arranged on the top wall and the bottom wall of the measuring pipe, and are connected with the input end of the second differential pressure transmitter; the signal output end of the second differential pressure transmitter is connected with the signal input end of the flow totalizer; an airinlet hole and an air outlet hole at two ends of the measuring pipe are respectively connected with pipeline joints which can be in butt joint with the water-containing natural gas transmission pipeline; the inner diameter of each pipeline joint is equal to that of the water-containing natural gas transmission pipeline, and the inner diameter of the measuring pipe is larger than that of each pipeline joints. After the device is applied, the flow of natural gas in the water-containing natural gas transmission pipeline can be relatively accurately measured.

Description

technical field

[0001] The invention relates to a gas flow measuring device used in a gas pipeline, in particular to a natural gas flow measuring device used in a water-containing natural gas pipeline. Background technique

[0002] In the prior art, the measuring device for measuring the fluid flow in the pipeline mostly adopts a Bitobar flowmeter, and the structure of the Bitobar flowmeter mainly includes a Bitobar sensor, a differential pressure transmitter and a flow totalizer, and the Bitobar sensor A total pressure conduit and a static pressure conduit are connected to the differential pressure transmitter, and the signal output end of the differential pressure transmitter is connected with the signal input end of the flow totalizer. When the Bitobar flowmeter measures the fluid flow in the pipeline, the Bitoba sensor is inserted vertically into the pipeline, and the differential pressure transmitter converts the total pressure signal and the static pressure signal tran...
