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.
Product Features
● Enables real-time concentration or density measurement for direct product process control;
● Provides accurate, reliable 5-digit real-time readings (with 4 decimal places);
● Converts measured physical parameters into a standard 4-20mA current signal;
● Delivers real-time current and temperature readings;
● Allows direct on-site parameter setting and commissioning via simple menu access;
● Includes pure water calibration, fine-tuning, and temperature compensation functions;
● Offers selectable anti-corrosion materials for wetted components.
Applications
● Large-scale Coffee Breweries for coffee extract density measurement in hot/cold brew tanks, post-extraction pipelines and filling lines;
● RTD Coffee Production Plants for mixed coffee liquid density monitoring in ingredient blending tanks, homogenization lines and bottling lines to ensure stable flavor ratios;
● Instant Coffee Factories for coffee slurry density tracking in evaporation chambers, concentration tanks and spray drying feed lines;
● Coffee Concentrate Manufacturers for concentrate density control in dilution tanks, aging vessels and packaging lines to prevent over/under-concentration and meet customer-specified dilution ratios;
● High-Volume Specialty Coffee Cafés for espresso or batch cold brew density measurement in extraction lines and holding tanks;
● Flavored Coffee Drinks Plants for flavored coffee mixture density monitoring in syrup blending lines, dairy/non-dairy mixing tanks and filling lines to preserve flavor balance and consistent mouthfeel;
● Coffee Waste Recovery Facilities for residual coffee liquid density measurement in effluent pipelines and recovery tanks to identify high-value extract residues and optimize resource recycling.
