Beer Monitor

To determine 3 crucial components of beer production: OG, extract and alcohol

The Centec Beer Monitor is a specific variant of the CombiTec which combines the functionality of both the RhoTec (density measurement) and SonaTec(sound velocity measurement).

Using the density and sound velocity properties of each liquid, the correlation between those 2 properties and concentration are defined by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec has developed polynomials for a large number of products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor.

The Beer Monitor is designed for those applications which require maximum sensitivity at the highest accuracy. It is easy to operate and maintenance-free.

A Closer Look

For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Using electromagnets, the tube is excited to oscillate at the resonant frequency. At the same time, an integrated reference oscillator measures the oscillation characteristics. Even the smallest changes in fluid density have an impact on the detected signal and are identified with highest precision. 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.

Using the density and sound velocity properties of each liquid, the correlation between those 2 properties and concentration are defined by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec has developed polynomials for a large number of products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor.
