Brewery 23 Perspectives in Liquid Process Analytics News INGOLD Leading Process Analytics Less Hassle and Easier to Use Dissolved CO2 Sensor for Just the Right Sparkle Different beers may have different levels of dissolved carbon dioxide. So, during production breweries need a CO2 sensor that not only provides accurate measurements, but is also easy to handle between products. For Boulevard Brewing, an intelligent CO2 sensor provides the answer. Large specialty brewery understands the importance of giving Boulevard Brewing Company is the largest consumers just the right effervescence specialty brewer in the US Midwest, with for its various products, and so the full or partial distribution across 25 states. brewery monitors dissolved CO2 levels to Since its founding in 1989, the brewery has control carbonation and ensure proper remained dedicated to the craft of produc- dosing. ing fresh, flavorful beers using traditional ingredients and the best of both old and Boulevardʼs production regime means new brewing techniques.

Mr. Pauwels is very pleased with the sensorʼs ease of installation, reliability, and the fact that it measures quicker and more accurately than their previous sys- tem. More importantly, the InPro 5500 i does not require calibration between product changes, therefore saving time and simplifying operations.

The turbidity signal is available on a standard 4 – 20 mA output and is integrated in a setup to control a three-way valve. The turbidity signal is high as long as yeast flows through the outlet pipe and the yeast is transferred to the recovery plant. Once the yeast is replaced by beer in the pipe the turbidity decreases. At a defined set point the valve is switched to transfer the beer to the maturation tanks. Storage tanks A similar setup is possible in the outlet of storage tanks. The residual yeast is re- moved from the beer in order to avoid an overload of the downstream filtration unit which would lead to an unwanted decrease of the operating time of the filter.
