Paper Abstract

To obtain the suspending state and position of object in opaque liquid is significantly important and there often meet many problems especially in the condition that suspending object will interact with the liquid. Traditional detection methods measurement accurate is too low or it's harmful to human health. One novel ultrasonic detect method was brought forward. Through analyzing the test environment and the features of ultrasonic test, positive and negative differential ultrasonic measure principle is presented. The experimental plat is setup and applied to secondary magnetic buoyancy object position measurement in the novel magnetic fluid inertial sensor. The results show that the secondary magnetic buoyancy position and its suspending state are accurately measured.
