We have pleasure in introducing our superior variable area flow meters and rotameters and industrial rotameters with special types offered for general industrial service and instrumentation requirements. Glass tube rotameters are offered where general flow measurements are within the limitations imposed by pressure rating of the glass metering tubes. For higher pressure ratings we offer metal metering tubes. Rotameters and industrial rotameters manufactured are of panel mounted types as well as pipe line mounted types. The pipeline mounted instruments are constructed to withstand pipeline installation stress, strain and vibrations. The unique gland arrangement ensures zero leakage and long life to the metering tube.
