Application:
SONATEC is a high-precision sound velocity sensor for determining sound velocities and concentrations (e.g., of acids or alkalis). The sensor can be used, for example, for phase detection.
SONATEC - Measurement of sound & concentration (2-component mixture)
The SONATEC sound velocity sensor continuously measures the speed of sound through liquids. The instrument is designed for applications requiring maximum sensitivity and the highest accuracy. It is easy to use and maintenance-free. To measure the speed of sound, a sound pulse is generated by a piezoelectric element in an ultrasonic transmitter. It travels perpendicular to the product flow towards an ultrasonic receiver, where it is detected. Since the distance between the transmitter and receiver is known, the speed of sound can be easily determined by measuring the time it takes the sound signal to travel. As a specific property of each liquid, the relationship between concentration and speed of sound can be described by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec knows the polynomials for a large number of products. Temperature drift of the measurement signal is automatically compensated by an internal Pt1000 sensor. SONATEC can display sound velocity and concentration in various units. For measuring the speed of sound in tanks, Centec offers a range of specially designed SONATEC sensors.
