On-line Ethanol Monitor

Supplier: B-R Controls

The Alcohol Monitoring system from Anton Paar is the most accurate on-line density transducer available, which continuously measures the density, % H2O and alcohol (ethanol)concentration.

The Anton Paar Alcohol monitor consists of a density transducer DPRn427(I) and an mPDS evaluation unit. Its high accuracy and reliability ensure efficient quality control and product monitoring of the ethanol concentration at the rectifier column (190 Proof) and condenser (200 Proof) for industrial ethanol producers or at the outlet of the pot still and in blending process for spirits distilleries.

How is the density measured?

The DPRn 427(I) transducer contains an oscillating U-tube system. It is excited and kept oscillating at its resonant frequency by two coils and an electronic circuit. The oscillation period and sample temperature are measured and transferred to an evaluation unit (mPDS 2000V3) for data processing.
