Helium leak detection system
Real-time flow rate of each flow meter is monitored by the host computer software to prevent the evaporator from not being filled with helium. In case of abnormality, the corresponding helium filling pipeline should have a clear distinction mark for easy targeted judgment. At the same time, an alarm signal is output, and a three-color light alarm prompt is given.
