The invention relates to instrument making, in particular to devices for measurement of amount of gas that is pumped in large diameter and high pressure pipes. Device for measurement of gas flow rate comprises several same turbine meters, each of those has body in which turbine is installed, on its one blade magnet is fixed, electronic device for calculation of revolutions of turbine, pipes that direct gas to turbine, inlet and outlet pipes that with common flanges are connected to main pipes with large diameter and high pressure. Reliable measurement of amount of gas in main pipelines is provided, at that error of measurement does not differ from error of measurement of gas with those when it flows in pipes with medium diameter at respective pressure. |
