To improve our production ability on air flow meter, my company is working on new sonic nozzle calibration equipment.

This equipment could be used to calibrate vortex flow meter, thermal mass flow meter, orifice palte flow meter, and so on.

Its equipment accurcy is much better than normal air clibration system. 

This equipment will be finished within one month and the production of air flow meter in my company will be improved largely.
