Two-phase Flow Flow Measurement Technology Research

Problem of two-phase flow frequently appears in such many industrial processes This paper uses differential auto-correlation method to measure the velocity of two-phase flow, and also gives a preliminary analysis to the measurement of phase-density Based on the above content , the paper designs capacitance senor and signal detecting translation circuit that can be put into the computer through data acquisition It also compiles test software by using LabVIEW as well as design a measure device to test the flow rate and phase-density of gas-liquid two-phase flow At the end of the paper a measurement experiment on flow rate and phase-density is conducted whose result demonstrates that the measurement method chosed is correct...
