Description
Technical Description – Sonatec
Measurement of Sound and Concentration
SONATEC is a highly precise sound velocity sensor for determination of sound velocities and concentrations (e. g. of acids, caustics, emulsions, or solvents). The sensor can be used for instance for phase detection and for monitoring of crystallization processes.
A Closer Look
The sound velocity sensor SONATEC continuously measures the velocity of sound through liquids. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For sound velocity measurement a sound pulse is created by a piezo element in a sonic transmitter. It moves perpendicular to the product flow towards a sonic receiver where it is detected. Since the distance between transmitter and receiver is known, the sound velocity can easily be calculated by measuring the travel time of the sonic signal. As a specific property of each liquid, the correlation between concentration and sound velocity can be described by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec know the polynomials for many products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor. SONATEC can display sound velocity and concentration in various units. For sound velocity measurement in tanks, Centec offer a variety of specially designed SONATEC sensors.
