OMEGA® FL-1800 Series Flowmeters are designed for use with corrosive materials. These special flowmeters utilize PVDF and glass wetted parts for excellent corrosion resistance where standard rotameters would be unacceptable. Because of this construction, these flowmeters can be used with most acids and bases, in addition to working with many organic solvents.
