Applications of ultrasonic liquid concentration detection
The principle of ultrasonic liquid mud concentration detection is based on the ultrasonic wave in the liquid velocity and the liquid concentration and temperature . According to the principle of acoustics, the velocity of ultrasonic propagation in the liquid is a density function of the elastic modulus and density of the liquid. The velocity of the ultrasonic transducer for depth varies with the elastic modulus or density of the liquid and is also a function of the mass concentration and temperature of the solution. Therefore, as long as detecting ultrasonic conduction velocity under different temperature , you can determine the liquid mass concentration. Scientists have designed a yeast concentration detection system based on ultrasonic transducer to study the barm cell concentration and ultrasonic propagation time and temperature in monument production, and discuss the factors that affect the measurement program to achieve the on-line measurement of yeast concentration in beer production.
