device for metning of fixed innehallet in a suspension

摘要

Disclosed are a method and apparatus for measuring the density of a suspension wherein the suspension to be measured is first subjected to pressurization or depressurization in a closed container by means of a compressor or a vacuum pump to extinguish air bubbles and gas bubbles which would otherwise cause measurement error, and the measurement of the density of the suspension is then achieved with high exactitude in a bubble free state.
