Application of Tuning Fork Density Meters and Magnetic Level Gauges in the Brewing Process

Customer Case | From "relying on experience" to "relying on data": This winery has upgraded its century-old brewing techniques using KEYILE instruments.

Case Details

“
	Winemaking is a refined craft passed down for thousands of years. From raw material fermentation to distillation and aging, the parameter control at every stage directly determines the flavor and quality of the wine. Recently, we provided a well-known domestic winery with a process measurement solution centered on magnetic level gauges and tuning fork density meters, helping the client achieve precise control and digital upgrade of the brewing process.

01
Industry Background and Customer Challenges

Baijiu brewing is a typical cross-industry of fine chemicals and food and beverage, and its production process has stringent requirements for monitoring the state of fluids and materials.

Fermentation and storage: Real-time monitoring of the liquid level in the tanks is necessary to ensure a stable fermentation environment and prevent the risk of overflowing or burning of empty tanks.
Distillation and blending: Liquid density is a core indicator for determining alcohol content and body concentration. Accurate density data is crucial for ensuring consistent flavor across every batch.

The core pain point that the winery previously faced was:

Liquid level monitoring is inefficient: Traditional glass tube level gauges are easily broken, provide unclear readings, and cannot achieve remote monitoring, relying on manual inspection, which is inefficient and poses safety hazards.
Density measurement is lagging: It relies on laboratory sampling and testing, resulting in delayed data feedback and an inability to guide blending processes in real time, easily leading to batch-to-batch quality fluctuations.
High requirements for adaptability to operating conditions: The production environment involves certain vibrations and temperature changes, requiring measuring instruments to have high stability and anti-interference capabilities.

Customized solutions

Based on the unique characteristics of the winery's brewing process, we have tailored the following instrument combination solution for our clients:

Stainless steel sanitary magnetic level gauge

Program Highlights：

Made entirely of hygienic stainless steel: Meets food-grade safety standards, resistant to alcohol corrosion, eliminates the risk of media contamination, and is perfectly suited for wine storage tank conditions.
Intuitive and clear, safe and reliable: Red and white indicator bars clearly show the liquid level, allowing for quick readings even in dimly lit workshops; no mechanical transmission parts, maintenance-free, and eliminates the risk of leakage.
Remote transmission function: Equipped with a remote transmitter, liquid level data can be uploaded to the central control room in real time, enabling 24-hour uninterrupted monitoring and completely eliminating the need for manual inspection.

Sanitary online tuning fork density meter

Core product advantages:

Real-time online, no sampling required: Directly installed on process pipelines, eliminating the need for manual sampling and testing. Millisecond-level response time allows density data to be fed back to the production line in real time, completely solving the problem of untimely process adjustments caused by laboratory testing delays.
Ultra-high precision, reliable data: Based on the resonant frequency measurement principle, accuracy reaches ±±0.001g/cc, far exceeding traditional specific gravity methods. It can accurately capture minute changes in alcohol concentration, providing reliable data support for blending processes.
Strong anti-interference, stable and durable: Unaffected by medium temperature, pressure, viscosity, and on-site vibration, it maintains stable data without drift even under complex winery conditions, requiring no frequent calibration for long-term operation.
Hygienic design, worry-free compliance: Made of 316L stainless steel with a clamp-type quick-installation structure, it has no dead corners, is easy to clean, and fully complies with GMP hygiene standards in the food and beverage industry, avoiding the risk of cross-contamination of alcohol.
Maintenance-free design, reduced costs: With no moving parts, there are no wear and blockage issues. Routine inspection is only required, significantly reducing instrument maintenance and manual calibration costs.

03
Project results and client feedback

After the solution was implemented, the winery achieved remarkable results in production control and quality improvement:
✅	Increased Production Efficiency: Automated acquisition and remote transmission of liquid level and density data reduce manual inspection frequency by 80%, allowing the central control room to monitor production status in real time.
✅	Enhanced Quality Stability: High-precision data from the tuning fork density meter guides blending in real time, minimizing deviations in liquor concentration. This significantly improves flavor consistency across different batches, increasing the rate of high-quality products by 5%.
✅	Safety and Compliance Assurance: The magnetic level gauge eliminates the risk of glass tube breakage, and the sanitary-grade materials meet food safety production requirements, successfully passing inspections by relevant regulatory authorities.

Customer testimonials
"In the past, blending relied entirely on the experience of master craftsmen. Now, with tuning fork density meters, the data speaks for itself, giving us much more confidence. The magnetic level gauge also eliminates our worries about overnight spills. This equipment has helped us make traditional brewing more precise and modern."
