ASTM D7777 - 13 Standard Test Method for Density, Relative Density, or API Gravity of Liquid Petroleum by Portable Digital Density Meter.
Application:
The digital density meter, also called as specific gravity hydrometer, is an analytical instrument used in laboratories and factories for measuring the density of liquid samples and other related parameters of liquids. Among the many types of density meters available, the most reliable version is the one whose working principle is based on 'Oscillation of the U-tube'. The underlying principle of this instrument is the Archimedes' principle in combination with microelectronics technology.
