Ethanol Measuring System EMS
The Ethanol Measuring System (EMS) continuously records mass flow and alcohol concentration in the process line. Based on these measured values, the system calculates the alcohol-water mixture (AWM) as well as pure alcohol at 20 °C and counts the quantities for official registration.
The EMS is designed as a frame-mounted system and is also suitable as a replacement or modernization solution for existing, technically outdated measuring lines – including reliable evaluation and documentable counting.
Key technical points
- Coriolis flow measurement in the main line (mass flow)
- Density measurement in the bypass for determining alcohol concentration
- Evaluation computer processes both signals, counts volumes, stores data power-failure-proof, and displays the average concentration
- AWM and pure alcohol metering (20 °C) for official registration
- Sensors, valves, and pumps integrated in a stainless steel frame
- Evaluation computer (including printer and counters) installed in the control cabinet outside the ATEX area
- System and control cabinet prepared for official sealing
- Individual acceptance and inspection by the BfB
Process value
Continuous, power-failure-proof inline recording and authority-compliant metering of ethanol quantities – without media interruption.
FAQ
Q: How is the alcohol concentration measured?
A: Via density measurement in the bypass; the mass flow is measured in the main line using a Coriolis flow meter.
Q: Is the system ATEX-capable?
A: IP65; optional ATEX (Ex II 2G EEx d IIC T6). The control cabinet is located outside the ATEX area.
Q: Which industries typically use EMS?
A: Bioethanol production, monopoly distilleries, and applications after dealcoholization.
Application
The Ethanol Measuring System (EMS) is used wherever ethanol flows in the process must be continuously recorded and documented in a traceable manner. The system provides complete inline recording of mass flow and alcohol concentration and calculates AWM as well as pure alcohol at 20 °C for official registration.
Typical fields of application:
- bioethanol production
- monopoly distilleries
- measurement points after dealcoholization
Measurement Concept
- Mass flow: measurement in the main line via Coriolis flow meter
- Concentration: parallel measurement via density measurement in the bypass
- Evaluation: evaluation computer processes both signals, counts volumes, stores data power-failure-proof, and displays the average concentration
Modernization / Renewal
If existing measuring lines are outdated or need replacement, the EMS is a structured, individually planned frame-mounted system for the replacement or modernization of ethanol measurement – including reliable evaluation and documentable counting.
