description The utility model relates to a gas flow detection device. The gas flow detection device consists of a roots blower, an electric ball valve, a standard flowmeter, an automatic blind plate device, a detected meter group, a detection pipeline group, a PLC (programmable logic controller), a cable and an industrial personal computer, the detection device adopts a positive pressure method to control the stability of the flow rate through the variable frequency of the roots blower and the openness of the ball valve, a roots flowmeter is adopted as a standard meter, the detection pipelines are connected with one another through manifolds, main detection pipelines are DN15mm, DN25mm, DN40mm and DN50mm; the flow range is (0.05-50)m /h; and the accuracy class reaches 0.1.
