JC-CBS Series Ultrasonic Acid-Alkali Concentration Meter

The JC-CBS series ultrasonic acid-alkali concentration meter is a high-precision online analysis instrument. This instrument uses the principle of ultrasonic sound velocity measurement combined with multiple detection technologies to precisely measure the concentration of acid and alkali solvents in production processes.

Ultrasonic detection is unaffected by the turbidity, color, or conductivity of the medium and is not disturbed by flow state or impurities. The built-in high-precision thermistor temperature measurement element and durable sensor design ensure the real-time accuracy of the instrument.

Ultrasonic Signal Transmission and Reception:

The ultrasonic emission probe emits an ultrasonic signal, which travels through a certain concentration of liquid to reach the opposite ultrasonic receiving probe. This determines the total time taken for the ultrasonic signal transmission. Dividing the distance by the time gives the ultrasonic speed.

working principle

Relationship between Ultrasonic Speed and Concentration or Density:

Within a certain range of concentration or density, the speed of ultrasonic signal propagation (v) in the liquid medium is a function of concentration or density (c) and temperature (t).
