Coriolis Mass Flow Meter Principle
The Coriolis mass flowmeter works based on the principle of Coriolis force. When a fluid passes through a rotating system, due to the effect of inertia, the fluid will generate a force perpendicular to the flow direction. The magnitude of this force is proportional to the mass flow rate of the fluid. It has nothing to do with other properties of the fluid (such as density, viscosity, etc.). The Coriolis mass flowmeter determines the mass flow rate of the fluid by measuring this force.
The metering system of a mass flowmeter includes a sensor and a transmitter for signal processing. The mass flowmeter is based on Newton’s second law: force = mass × acceleration (F = ma). When a particle with a mass of m moves at a speed V in a pipe rotating at an angular velocity ω about the P axis, the particle is subject to two components of acceleration and its force:
(1) Normal acceleration, that is, centripetal acceleration αr. Its magnitude is equal to 2ωr, toward the P axis;
(2) Tangential angular velocity αt, that is, Coriolis acceleration. Its value is equal to 2ωV, and its direction is perpendicular to αr.
Due to the compound motion, a Coriolis force Fc=2ωVm acts in the αt direction of the particle, and the pipe exerts a reverse force -Fc=-2ωVm on the particle.
When a fluid with a density of ρ flows at a constant speed V in a rotating pipe, any pipe with a length of Δx will be subjected to a tangential Coriolis force ΔFc: ΔFc=2ωVρAΔx (1)
Where A is the flow cross-sectional area of the pipe.
Since there is a relationship: mq=ρVA
So: ΔFc =2ωqmΔx (2)
Therefore, the mass flow rate can be measured by directly or indirectly measuring the Coriolis force of the fluid flowing in the rotating tube.
Coriolis Mass Flow Meter vs Magnetic Flow Meter
Mass flowmeter and electromagnetic flowmeter are two common flow metering devices. They play a very important role in industrial automation production. They can both be used to measure the mass or volume flow of fluids. But there are still some differences. The main differences between the two flowmeters are:
- Different measurement principles
Mass flowmeter is a flow measurement instrument developed based on the Coriolis force principle, which can directly measure the mass flow of fluids in closed pipes and the density of the medium.
Electromagnetic flowmeter measures the flow of fluids based on Faraday’s law of electromagnetic induction (that is, the magnitude of the induced electromotive force in a conductor is proportional to the rate of change of the magnetic flux in the conductor).
- Different scope of application
Mass flowmeter has a wide range of applications and can measure the flow of various liquid and gaseous media. It is suitable for application scenarios that require accurate measurement of mass flow. Such as flow measurement in chemical, pharmaceutical, food and other industries.
Electromagnetic flowmeter is suitable for flow measurement of conductive media. Such as acid and alkali liquids, electrolytes, sewage, etc. The measurement accuracy of non-conductive media such as petroleum, liquefied gas and other fluids is not high.
- Different accuracy and stability
Mass flowmeters have higher flow measurement accuracy for conditions such as high viscosity, large flow rate changes, and large temperature differences. It can reach ±0.2%~±0.5%.
Electromagnetic flowmeters are not affected by fluid temperature, temperature, turbulence, etc., and have high accuracy, which can reach ±0.5%.
- Different prices
Mass flowmeters have higher accuracy and stability, and are generally more expensive than electromagnetic flowmeters.

Coriolis Mass Flow Meter can measure multiple field variables such as flow, density, temperature, etc. at the same time. The transmitter has two output signals that can be configured separately. It can be used to display measured values such as flow, density, temperature, etc. One mass flow meter can replace multiple measuring instruments.
Sino-Inst’s T Series Coriolis Mass Flow Meter can be as small as DN3. It has a wide range of applications. In addition to normal fluid measurement, it can also measure industrial media that are difficult to measure with general fluid measuring instruments, such as high-viscosity fluids, various slurries, suspensions, etc.
