Density Applications Notes
Wine: MDM150 is rugged and portable density monitoring for quality wine production
Quick, accurate, repeatable density measurement; in the cellar or in the lab. The challenge is suger, which is the key to wine production. Density can be used to measure the sugar concentration (BRIX) in grape juice or other fruit juice (must) prior to crush and throughout the fermentation process. Traditionally this measurement was made using a glass hydrometer. The large volume of sample required and time to make the measurement means a glass hydrometer is not practical for large winery operations. Before grape or fruit harvest, the accuracy of sugar measurement in the juice is important in determining the timing of the harvest for the highest quality wine. During fermentation of the must, the sugar in the juice is converted into ethanol with carbon dioxide as a waste gas. Monitoring the density of the juice during this step in the process allows for optimal control of this conversion step for highest quality wines. Density (BRIX) should be measured at least once per day during fermentation. Monitoring the slope of the BRIX conversion slope allows the winemaker to adjust the temperature of the process for optimal wine quality. Solution The MDM150, the mobile density meter from Integrated Sensing Systems provides winemakers with the option of performing density measurements in the cellar or in the lab.
Beer: MDM150 is rugged and portable density monitoring for quality beer production
In a brewery, viscosity measurement plays an important role in the controlling the quality of the beer. It indicates the quality of the malt, predicts filtering times and is an indicator of the foam behavior of the finished beer.
The MDM150, the mobile density meter from Integrated Sensing Systems provides beer makers with the option of performing accurate density measurements in the brewhouse or in the lab. Only a few milliliters of wort or beer are required for making the measurement. There is no need for rinsing the density meter when measuring multiple beer samples. Yeast and dissolved CO2 in the beer will not affect the performance of sensor measurement. At the heart of the MDM150 is a patented, innovative, MEMS vibrating density sensor that is immune to the effect of gas bubbles in the beer. This assures accurate and consistent measurements that are available in seconds.
