Investigation on Measurement Method of Weight Volume Based on Acoustics

Abstract:

The measurement value of weight volume is important for correcting buoyancy influence in the mass measurement. Traditional measurement method of weight volume is hydrostatic method. It is the most accurate method currently, but it is a complicated process requiring the weight to be wetted in a reference fluid. To eliminate the influence of liquid against weight mass in the determination of weight volume of the hydrostatic method, the measurement method of weight volume based on acoustics is introduced in the paper. The results from 1 kg to 20 kg show accuracy of the measurement system is enough to measuring volume of class E weight. The relative extend uncertainty of measurement method of weight volume based on acoustics is less than 8×10^-4.
