Selection of mass flow meters

If the medium being measured is prone to scaling, using a mass flow meter may be affected by this scaling. Measuring scale on the tube wall can lead to inaccurate measurements or instrument failure. Therefore, it is recommended to choose a flow meter that can adapt to scaling conditions and is easy to clean. For media prone to scaling, mass flow meters equipped with scrapers or similar cleaning devices inside the measurement tube can be selected. This type of mass flow meter can clean scale buildup inside the measurement tube, ensuring that the measurement accuracy is not affected. Additionally, a positive displacement flow meter can also be used. Positive displacement flowmeters do not require a measuring tube; instead, they measure flow using devices such as screws or turbines. This type of flow meter is less prone to scaling issues, so it is also a viable option to consider. In summary, when selecting an appropriate flow meter for applications involving media prone to scaling, various factors need to be taken into account, including the properties of the medium being measured, as well as the cleaning and maintenance costs of the measurement pipelines. It is recommended to conduct a detailed assessment based on the specific circumstances before making a selection. .
