The following are the limitations of Coriolis mass flow meters in industrial, chemical, petrochemical, biomedical and other fields:

In the industrial field:

•Media limitations: Coriolis mass flow meters can only be used to measure the mass flow of non-corrosive media, but are not suitable for corrosive, high-viscosity or media containing particulate matter.

• Measurement range limitation: The measurement range of the Coriolis mass flow meter is limited by the size of the flow meter tube. When the flow rate exceeds the measurement range, the accuracy and precision of the flow meter will be affected.

In the chemical industry:

• Limitation of measurement accuracy: The accuracy of Coriolis mass flow meter is affected by the density and viscosity of the medium. The measurement accuracy of complex media such as high viscosity and multi-phase flow is low.

• Temperature and pressure limitations: The measurement range and accuracy of the Coriolis mass flow meter will be affected by the temperature and pressure of the medium. The measurement accuracy is lower in high temperature and high pressure environments.

In the petrochemical industry:

• Medium characteristic limitations: When measuring different types of petroleum media, the Coriolis mass flow meter needs to correct the temperature, pressure, viscosity and other characteristics of the medium, otherwise the measurement accuracy will be affected.

• External influences: There are many external interference factors in the petrochemical industry environment, such as vibration, electromagnetic field interference, etc. These factors will also affect the measurement accuracy of the Coriolis mass flow meter.

In the field of biomedicine:

• Difficulty in cleaning: When measuring biological products, Coriolis mass flow meters need to be cleaned repeatedly to ensure measurement accuracy and production quality. However, due to the special properties of biological products, cleaning is difficult.

• Cost limitation: Compared with other types of flow meters, Coriolis mass flow meters are more expensive and may not be suitable for the production of some low-cost biomedical products.

It should be noted that these limitations do not mean that the Coriolis mass flow meter has lost its application value in the above fields, but it requires a clear understanding of its advantages, disadvantages and limitations, and the selection and optimization of appropriate measurement solutions in practical applications.
