WebA hydrometer is an instrument that measures the specific gravity (relative density) of liquids—the ratio of the density of the liquid to the density of water. For wine and beer making, a simple hydrometer is used to determine the amount of alcohol in the brew in order to decide when it is ready to be placed in bottles. Water meter. WebHYDROMETER The value of effective depth (L) for each hydrometer (see Figure 1) and the sedimentation cylinder in which it is to be used should be calculated as follows: For all readings, the hydrometer is placed in the suspensions 20 seconds before each reading. http://www.grlevelx.com/manuals/grlevel3_2/hca.htm sample introducing a guest speaker
