After passing through the medium, the amplitude of ultrasonic wave exhibits exponential attenuation as the concentration increases, and its measurement accuracy is calibrated through formula coefficients. Adjust sensor related parameters according to the actual working conditions of pulp and tailings concentration monitoring to achieve accurate measurement. Ultrasonic concentration meter is a mainstream equipment for monitoring pulp concentration in metal mines.

In view of the diversity of iron ore production processes, the principle of one-to-one correspondence between slurry pipelines and sensors was adopted to re select the ultrasonic concentration meter sensor. Adjust the sensor spacing considering the size of the pulp. Calibrate the ultrasonic concentration meter according to the actual process test data. The test results show that the measurement accuracy of ultrasonic concentration meters in iron ore plants has been improved, and the use of zero point calibration and three point calibration methods for data calibration of ultrasonic concentration meters will become the direction of application in iron ore plants.
