CAUTION
Select the material of wetted parts with careful consideration of process characteristics. Inappropriate
selection may cause leakage of process fluids, which greatly affects facilities. Considerable care must be
taken particularly in the case of strongly corrosive process fluid such as hydrochloric acid, sulfuric acid,
hydrogen sulfide, and sodium hypochlorite. If you have any questions about the wetted part construction
of the product, be sure to contact Yokogawa.
