Installation and operation of densitometers

摘要

A densitometer is an electromechanical device used to measure the flowing density of a stream. Because it measures density, a densitometer is often called a density meter. This paper uses densitometer and density meter interchangeably. The stream is usually a single-phase liquid, but instead could be a single-phase gas or vapor. In the oil and gas industry, a densitometer usually measures the density of liquid mixtures or hydrocarbon products meeting some specification. Other industries use densitometers to measure the density of fluids like milk, vinegar and syrup.
