In the corrosion resistance tables, different letters are used to indicate the suitability and durability of materials when exposed to various liquids. Below is the meaning of each symbol:
- A (Applicable / Suitable) – The material is highly resistant to corrosion and is suitable for use with the given liquid.
- B (Usable but with a Short Lifespan) – The material can be used, but its lifespan may be significantly reduced due to potential corrosion or wear.
- N (Not Usable / Not Recommended) – The material is not resistant to the specified liquid and should not be used.
- R (Room Temperature) – The data applies specifically to room temperature conditions.
- S (Boiling Point / High Temperature) – The material’s performance is evaluated at or near the boiling point of the liquid.
- Sat (Saturated Solution) – The information is relevant for a saturated solution of the given liquid.
These ratings serve as a guideline to help users choose the most suitable electrode and lining materials for specific chemical environments, ensuring the durability and efficiency of electromagnetic flow meters.
