Difference between stainless steel rotor flowmeter and PTFE rotor

Project Overview

The main feature of the stainless steel rotameter is its sturdy and durable structure, which is made of stainless steel and has good corrosion resistance. This enables the stainless steel rotameter to operate stably for a long time when handling liquids and gases, and is especially suitable for situations with corrosive media. It is widely used in chemical, petroleum, pharmaceutical and other fields.

In contrast, PTFE rotameter uses polytetrafluoroethylene (PTFE) material to make the rotor. PTFE is a material with excellent corrosion resistance and low friction coefficient, allowing the PTFE rotameter to handle various corrosive media and high-purity liquids. Therefore, PTFE rotameter is widely used in chemical, pharmaceutical, food and other industries, especially in situations where the medium is required to be free from contamination.

There are some similarities and differences in the use of stainless steel rotameter and PTFE rotameter. Stainless steel rotameter is suitable for flow measurement under general working conditions, especially suitable for low temperature and pressure situations. Due to its material characteristics, PTFE rotameter is more suitable for handling media with certain corrosiveness and higher temperature, and its temperature range is usually wider.

In summary, there are obvious similarities and differences between stainless steel rotameter and PTFE rotameter in terms of material properties and application range. Which type of flow meter to choose should be reasonably selected based on specific process requirements, medium properties, temperature and pressure and other factors to ensure that the flow meter can operate normally and stably and achieve accurate measurement results in actual applications.
