Industry Background

In the beverage industry, carbon dioxide (CO₂) is a critical process gas. It is widely used for carbonation, filling protection, pressure control, and product transfer. The stability and accuracy of CO₂ supply directly impact product taste, shelf life, production efficiency, and operating cost.

With increasing focus on quality consistency, automation, and energy management, beverage manufacturers require a reliable and accurate CO₂ flow measurement solution.

CO₂ Applications in Beverage Production

CO₂ is involved in multiple key stages of beverage processing:

• Carbonation of soft drinks, sparkling water, and beer

• Oxygen purging during bottle and can filling

• Tank head pressure control

• Product transfer and line stabilization

Each application demands stable flow control and precise gas dosing, especially under fluctuating production conditions.

Measurement Challenges

Measuring CO₂ in beverage plants presents several technical challenges:

• Fluctuating pressure and flow rates during carbonation and filling cycles

• Wide turndown requirements due to varying production speeds

• Need for mass flow measurement for accurate consumption analysis

• High CO₂ cost, requiring precise monitoring to reduce waste

Traditional flow meters may struggle to deliver stable and repeatable results under these conditions.
