Strong acids and bases are not common liquids, and their measurement conditions have high requirements for flow meters. The selected flow meter shall not be corroded in strong acid or alkali environments. The electromagnetic flow meter using 316L electrodes precisely meets this measurement condition, so electromagnetic flow meters can be used to measure strong acid and alkali liquids.
The part in contact with the liquid is not only the electrode material, but also the inner lining. Therefore, the inner lining should also choose materials suitable for strong acids and alkalis, and polytetrafluoroethylene material precisely meets this condition, which has a high cost-effectiveness and is a commonly used inner lining material. Lined with polytetrafluoroethylene, the electrode material is 316L, which can better meet the requirements for measuring strong acid and alkali liquids. Therefore, manufacturers of electromagnetic flow meters generally recommend this combination.
