A new airborne pattern mass flowmeter is presented, It’s theoretical model and practical system structure are given. The mass flowmeter consists of a driver and inductive wheels of mass. The driver provides energy for running of component in the interior of flowmeter, and flux of oil is measured by the inductive wheel of mass,this is difference between the mass flowmeter and other mass flowmeter. The Two signals from the mass flowmeter is filtered by no change of phase, and the phase difference is given by zero passage arithmetic. The relation between mass flowmeter and phase difference is validated. the experiment demonstrates that the mass flowmeter is higher Accuracy, is good at anti-vibration, anti-tilt, bearing greater acceleration and less power consumption.
