An improved ring method for calibration of hydrometers
description This study describes an improved hydrometer calibration method using a ring type sinker as a reference standard mass. Ring method offers simple yet effective hydrometer calibration method with comparable performance to other hydrometer calibration methods. This work also reports a ring method experimental setup for calibrating hydrometers. The theoretical calculation was developed and tested with experimental data. This calibration method can be used for any surface tension and reference temperature design of hydrometer. A suitable dimension of standard ring was used to sink hydrometers into distilled water. The distilled water was used as standard liquid, traceable to a standard solid density determined by hydrostatic weighing method.
