A Coriolis meter is comprised of two main components, a sensor and a transmitter. Coriolis meter infer the gas mass flow rate by sensing the Coriolis force on a vibrating tube or tubes. The conduit consists of one or more tubes which are vibrated at their resonant frequency.Coriolis flow meters allow the direct measurement of mass flows. Direct mass flow measurement eliminates inaccuracies caused by the physical properties of fluids. Thermal flow meters, on the other hand, allow indirect measurement of mass flows.

Coriolis meter principle

Coriolis mass flow meters measure mass through inertia. A liquid or gas flows through a tube which is being vibrated by a small actuator. This artificially introduces a Coriolis acceleration into the flowing stream, which produces a measurable twisting force on the tube resulting in a phase shift.Coriolis meters are extremely accurate. In fact, a Coriolis meter is often used as a standard for checking other flow- meters. A liquid coriolis meter accuracy of 0.10% is common, and 0.05% is readily available. Gas mass flow accuracy to 0.25% is available, although 0.35–0.5% is more common.Coriolis meters provide 0.1-2% of rate inaccuracy over a mass flow range of up to 100:1. In general, curved tube designs provide wider rangeability, while straight-tube meters are limited to 30:1 to 50:1 and their accuracy is lower.

Coriolis meters have several advantages, including:

High accuracy: Coriolis meters are highly accurate and can measure mass flow rates with a high degree of precision, making them suitable for use in critical applications such as custody transfer.

Wide range of applications: Coriolis flow meter can be used to measure the flow of a wide range of fluids, including liquids, gases, and slurries, making them suitable for use in a variety of industries.

High turndown ratio: Coriolis meters have a high turndown ratio, meaning they can accurately measure flow rates over a wide range of values, from low to high.

No moving parts: Coriolis meters do not have any moving parts that come into contact with the fluid being measured, which makes them less prone to wear and tear and reduces maintenance requirements.

Ability to measure multiple parameters: Some Coriolis meters are capable of measuring not only mass flow rate but also density, temperature, and other parameters, providing more information about the fluid being measured.

Coriolis meters offer high accuracy, versatility, and reliability, making them an attractive option for many industrial applications.

Coriolis meters have a wide range of applications in various industries, including:

Oil and gas: Coriolis meters are commonly used for custody transfer applications in the oil and gas industry, where accurate measurement of mass flow rates is critical.

Chemicals: Coriolis meters are used in the chemical industry to measure the flow of liquids and gases in various processes, such as mixing, blending, and batching.

Pharmaceutical: Coriolis meters are used in the pharmaceutical industry to measure the flow of liquids and gases in various processes, such as mixing, filling, and packaging.

Food and beverage: Coriolis mass flow meter are used in the food and beverage industry to measure the flow of liquids and slurries, such as milk, juice, and beer. They are also used to measure the density of sugar syrup and other viscous fluids.

Water and wastewater: Coriolis meters are used in water and wastewater treatment plants to measure the flow of liquids and gases, such as chemicals, sludge, and gases like methane.

Overall, Coriolis meters can be used in any application that requires accurate measurement of mass flow rates, density, and other fluid parameters, making them a versatile tool in various industries.

Beijing Sincerity coriolis meter manufacturer has developed over years to manufacture the Coriolis Mass Flow Meters industries. Through continuous research, development and transformation, we have become the leader of the Coriolis Mass Flow Meters industries in China.The Coriolis Insertion Density Meters could be used for the detection of the liquid's density. The insertion density meters are the best choices for the proccess control as the basic parameters of density, and also for the quality control with the solid percentage or the concentration for references.
