Beschreibung
Zusammenfassung:	The invention discloses a multi-channel gas flow automatic detection system. The multi-channel gas flow automatic detection system comprises a pneumatic device and an electric control device. The pneumatic device comprises an electric control proportional valve connected with the electric control device, a pressure reducing valve is arranged at the gas inlet end of the electric control proportional valve, and the gas outlet end of the electric control proportional valve is connected with a multi-channel solenoid valve through a flow measurement device. A pressure transmitter connected with the electric control device is arranged between the multi-channel solenoid valve and the flow measurement device. By means of the multi-channel gas flow automatic detection system, the function of stably outputting pressure gas flow through a single channel or multiple channels can be achieved, meanwhile, the pressure of the output gas flow can be adjusted in real time, and downtime of a flow tester is effectively avoided.
