In the experiments, it is measured that the ultrasonic velocities of hydrochloric acid solution of the different concentrations and temperatures. And it is also calculated that the velocity-concentration coefficients and velocity-temperaturecoefficients of hydrochloric acid solution.展开更多
文摘In this paper, it is discussed that an on-line ultrasonic hydrochloric acid concentration meter according to the relationship between the concentration, temperature and ultrasonic velocity of hydrochloric acid solution. In the experiments, it is measured that the ultrasonic velocities of hydrochloric acid solution of the different concentrations and temperatures. And it is also calculated that the velocity-concentration coefficients and velocity-temperaturecoefficients of hydrochloric acid solution.
