RHOTEC ALC-TAX

Application

RHOTEC ALC-TAX is a variant of RHOTEC and allows measuring alcohol during the production, when alcohol content needs to be determined by a certified instrument for reasons of taxation.

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. With decades of experience and our own laboratory facilities, Centec know the polynomials for a large number of products. 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.
