Application:

The ALCOHOL MONITOR is a variant of RHOTEC or SONATEC and allows the measurement of the alcohol (ethanol) content in mixtures of water and ethanol. Alcohol measurement is performed during the production of beer and beer-based mixed drinks.

ALCOHOL MONITOR

The ALCOHOL MONITOR utilizes the functionality of either RHOTEC (density measurement) or SONATEC (speed of sound measurement). The instrument is designed for applications requiring maximum sensitivity and the highest accuracy. It is easy to use and maintenance-free. For density measurement, the liquid flows through a thin, U-shaped tube within the sensor. Electromagnets excite the tube to vibrate at its resonant frequency. Simultaneously, an internal reference oscillator measures the vibration behavior. Even the smallest changes in the liquid's density affect the measured signal and are detected with the highest precision. For speed of sound measurement, a sound pulse is generated by a piezoelectric element in an ultrasonic transmitter. It travels perpendicular to the product flow toward 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 density, or 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 drifts of the measurement signal are automatically compensated for by an internal Pt1000 sensor.
