In this paper,we briefly consider the feasibility on acoustic measurement device of furnace velocity field,and develop a test device using acoustic measurement.With acoustic measurement technology,we can work out exact sound signal spreading time,and so,furnace field would be reconstructed.The device is a combination of some kinds of technologies;sound signal generating and receiving,A/D,Cubic Spline and relativity calculating,etc.Besides,a test is made to validate our device,and the result is satisfactory and shows good maneuverability,low cost and so on.This device could be applied well in practice.
