The density sensor RHOTEC ALC-TAX is a version of RHOTEC and allows continuous measurement of alcohol content during the production of beer, sparkling wine, cider and spirits. 

Advantages:

  • Most accurate technology to determine alcohol content
  • PTB-design type with calibration error 0,0001 g/cm³ for alcohol, alcohol-water-mixtures and water
  • In combination with different types of certified flow meters, the requirements of PTB and BfB (Federal
  • Monopoly Administration for Spirits) are met
  • Patented compact design with local display available
  • Hygienic execution and full CIP capability

Description

Description

The density sensor RHOTEC ALC-TAX continuously measures the content of alcohol. Meeting the requirements of PTB (Physikalisch Technische Bundesanstalt), the device is accepted and certified by German government authorities. It is easy to operate and maintenance-free.

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. As a specific property of each liquid, the correlation between concentration and density can be described by a mathematical polynomial. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor. RHOTEC ALC-TAX can display liquid density and solution concentration in various units.
