The function of closing valves during idle time: prevent the basal meter from ventilation when it is blocked;

The function of self-checking of valves: prevent the basal meter from being blocked when it is not used for a long time and clear the mechanical faults of valves;

Control plan for pulse error: double tongue tubes are adopted for reading, control module can inspect the breaking and damaging of thread automatically, the valves can be closed automatically.
