Gas Density Measurements

Analytical Instrumentation

Principle of gas density measurement: The relationship between temperature, pressure, and volume of a gas is given by: PV = nZRT where P is the absolute pressure, V is the volume, and n is the number of moles. Z is the compressibility factor, R0 is the universal gas constant, and T is the absolute temperature. …

Density Measurement – Vibrating Element Densitometers

Analytical Instrumentation

Vibrating Element Densitometers Principle: If a body containing or surrounded by a fluid is set to resonance at its natural frequency, then the frequency of oscillation of the body will vary as the fluid properties and conditions change. The natural frequency is directly proportional to the stiffness of the body and inversely proportional to the …

Different methods of Density Measurement

Instrumentation

Introduction Density is defined as the mass per unit volume. Specific gravity is a unitless measurement. It is the ratio of the density of a substance to the density of water, at a standard temperature. This term is also referred to as the relative density. The measurement and control of liquid density can be quite …
