WebIn general, glass tube rotameters can measure flows up toa bout 60 gpm water and 200 scfh air. A correlation rotameter has a scale from which a reading is taken (Figure 1). This reading is then compared to a correlation table for a given gas or liquid to get the actual flow in engineering units. WebA rotameter was designed to measure a gas flow. If the flow stopped or decreased substantially, the float (bobbin) dropped and interrupted a light beam. This triggered a low-flow alarm. The design had limitations. If the flow diminished only slightly, the light beam remained broken and the alarm light stayed on after the alarm bell was silenced ...
