Coriolis Density Meter is also called Coriolis Concentration Meter. It adopts the principle of operating under the special law of the Coriolis force of the moving liquid. The Coriolis force is related to the density of the liquid, so the density value of the liquid is measured. The concentration is calculated from the density and temperature. The Coriolis principle has high stability, high precision, good long-term stability, and no drift caused by the sensor. Coriolis Density Meter is used in many industries like oil refining, sugar, paper, and chemical. It measures weak acid-base solutions in the wine, salt, and printing industries.

Coriolis density meter industrial applications
The Coriolis density meter is based on the principle of special laws under the action of the Coriolis force of the moving liquid. The Coriolis force is related to the density of the liquid, so as to measure the density of the liquid; then according to the relationship between density and concentration The relational table obtains concentration values at a temperature of 20°C.
Coriolis density meter can be widely used in the detection of oil refining and blending in the petrochemical industry. The food industry is used in sugar industry, vegetable oil and beverage processing, etc. Production site, paper industry, measurement of weak acid-base solution in chemical industry, wine industry, salt, printing and dyeing and other industries. Due to the large flow pipe, it is especially suitable for occasions that are not dry or viscous. It is suitable for pipe installation.

Coriolis mass flowmeter is a kind of instrument that is commonly used at present and has relatively high stability and reliability of measurement accuracy. Coriolis mass flow meters are not only capable of measuring mass flow meters from Micro Motion, but also of media density.
When the Coriolis Density Meter measures density, its measuring tube vibrates continuously at a certain resonant frequency. Because the resonance frequency is a function of the fluid density. When fluids of different densities fill the vibrating tube, its vibration frequency will also change. Therefore, measuring the frequency change of the vibrating tube completes the density measurement. The linear relationship between the density and the vibration frequency of the vibrating tube.
This method is accurate and reliable in measurement, and is suitable for a wide measurement range of various fluid densities. The pressure loss of Coriolis Density Meter is very small, and it has inherent advantages in measuring the density of viscous fluids such as mud.
There are more and more requirements for density measurement in the current production process, and the accuracy of density measurement directly affects the quality of production process.
We Sino-Inst manufacture and supply many kinds of Coriolis Density Meters-Concentration Meters.
