OVAL DENSITOMETER FOR GAS SERVICE

Liquid

Gas

Steam

Density is a unit of measurement indispensable for specifying the nature and composition of a material. Especially, in the process control system of various fields of industries, density measurement for gas and liquid is treated as important in the quality control and in measuring the flow of mass. OVAL densitometer for gas services using state-of-the-art frequency modulation technologies can satisfy various requirements for industrial measurements. It can also contribute to labor saving, safety operation, quality control, cost management, and pollution prevention as a new-age industrial instrument successfully achieving the measurement and control of density that has been regarded as a difficulty among process parameters.

FEATURES

● High precision and excellent reproducibility
● High responsibility owing to the frequency-time measurement system in oscillation tube
● Extremely low effect of fluid temperature and no pressure effect
● Simple construction, high durability, and easy maintenance
● The natural frequency of the oscillation tube is high and there is no effect of external oscillation.
● Insertion type (DGI) densitometer can be removed without obstructing the fluid flow and no sampling system is required.
● By the installation of a safety instrument (Safety barrier) in the measurement circuit, intrinsically safe construction is attained.
● By the combination with vortex flowmeter, highly accurate mass measurement is available.
