Coffee Density Meter Inline

The inline caffeine concentration sensor contributes to flavor stability, waste reduction and scalable operations. It’s particularly valuable for industrial-scale operations involving coffee extracts, concentrates, ready-to-drink (RTD) beverages, and brewing processes. Density measurements help optimize flavor, ensure standardization, and improve efficiency, often complementing or integrating with Brix/refractometry for comprehensive control.

Working Principle

It employs an acoustic signal source to excite a metal tuning fork, causing the fork to vibrate at its natural resonant frequency. Notably, this resonant frequency exhibits a direct correlation with the density of the liquid that the tuning fork contacts. Subsequently, the density of the liquid can be determined through frequency analysis—with temperature compensation implemented to counteract temperature drift within the system, ensuring measurement accuracy.
