BEER MONITOR, Inline Analyser for Alcohol, Extract and Original Gravity, Centec

The BEER MONITOR is a specialised inline analyser from Centec, built on the COMBITEC platform for continuous, real-time measurement of alcohol, extract, and original gravity directly in the beer production process stream. It combines two complementary measurement technologies: RHOTEC, which determines product density using a vibrating U-tube method, and SONATEC, which measures the speed of sound ultrasonically. Alcohol content and extract are calculated from a mathematical model relating concentration, density, and sound velocity, while original gravity is automatically computed and displayed. Temperature deviations in the measurement signal are compensated automatically by an integrated Pt1000 sensor. The instrument is designed for hygienic food-grade environments, is fully CIP-compatible, and features a compact patented construction with optional local display.

Key Features BEER MONITOR

• Dual-technology measurement: RHOTEC (vibrating U-tube density) + SONATEC (ultrasonic sound velocity) — comprehensive inline product analysis from a single sensor.
• High-accuracy simultaneous measurement: alcohol ±0.02 vol. %, extract ±0.02 wt. %, original gravity ±0.03 °Plato.
• Response time ≤1 s — real-time process feedback for dynamic production environments.
• Automatic original gravity calculation — no manual calculation or offline sampling required.
• Automatic temperature compensation via integrated Pt1000 sensor.
• Hygienic design; fully CIP-compatible; wetted materials 1.4404 / 1.4435 / AISI 316L (Hastelloy and Tantalum available on request).
• Compatible with Varivent inline connection DN40–DN150; other connections available on request.
• Flexible I/O: 10 digital inputs (24 V DC), 2 analogue inputs (4–20 mA), 5 digital outputs (24 V DC), 4 analogue outputs (4–20 mA); Profibus DP optional or standard depending on configuration.
• IP65; 24 V DC; compact patented construction; optional local display.

Applications

The BEER MONITOR is suited to continuous inline monitoring and process control in beer production, beer-mixed beverage manufacturing, and any brewing process requiring high-sensitivity, high-accuracy measurement of alcohol, extract, and original gravity directly in the product flow — including fermentation monitoring, filtration control, blending, and filling line verification.

Installation and Safety Notes

Install inline using Varivent DN40–DN150 connections or alternative connections as specified. Power supply: 24 V DC. The instrument is fully CIP-compatible — no removal required for cleaning cycles.
