Measuring system for calculating high-temperature gas flow based on pressure difference

The utility model relates to a measuring system for calculating high-temperature gas flow based on pressure difference, which comprises a first pipeline, two second pipelines and two connecting pipelines which are coaxially arranged, and the gas inlet end and the gas outlet end of the first pipeline are respectively connected with the second pipelines through the connecting pipelines. The area of the gas passing section in the first pipeline is smaller than that of the gas passing section in the second pipeline, the area of the gas passing section in the connecting pipeline is gradually reduced from the second pipeline to the first pipeline, and the measuring system further comprises a first pressure sensor and a second pressure sensor. The high-temperature gas flow measuring device is convenient to industrially manufacture, when the high-temperature gas flow needs to be measured, the high-temperature gas flow measuring device is installed on a high-temperature air pipe to be measured, the gas flow can be rap
