Ethanol Measuring System EMS
Continuous Measurement of Mass Flow and Alcohol Concentration
The AlcoTax ethanol measuring system continuously measures mass flow and alcohol concentration in the flowing product. Litres of alcohol-water mixture and pure alcohol at 20 °C are calculated from these measurements and totalised for official recording.
Measuring Principle
A Coriolis flow meter measures mass flow in the main stream. In parallel, Centec density measurement in the bypass determines the alcohol concentration. The evaluation computer processes both signals, totalises the volumes and displays the average concentration.
Applications
- Bioethanol Production
- Monopoly Distilleries
- After Dealcoholisation
- Alcohol-Water Mixture
- Pure Alcohol at 20 °C
- Official Recording
- Concentration
- Mass Flow
In simplified form, the system is also used to measure and control concentration, flow and quantity in applications without customs relevance. The installation and control cabinet are prepared for official sealing.
