FMR20C Series Glass Tube Rotameter With 4-20mA Output
Introduction
The FMR20C series are remote-type glass tube rotameter with flow tubes made of either PC or high borosilicate glass. The PC version is ideal for non-corrosive, non-solvent media and supports up to 4.0 MPa pressure. The borosilicate glass version is suitable for corrosive media, with pressure resistance conforming to G/R/F standards. Available connection types include threaded, hose, flange, and sanitary clamp options. This series is compact, lightweight, aesthetically designed, and easy to install and maintain. It offers high measurement accuracy, low pressure loss, excellent repeatability, and reliable operation.
