- Easy-to-read direct reading gradations to depict dual SCFM and L/minute markings, reflecting both metric and English systems.
- Accurate medium-flow range measurements.
- Assembly of Aalborg®’s heavy-walled, fluted borosilicate glass flow tubes—with polycarbonate shields—in brass or 316 stainless steel frames.
- Standard Viton® seals, plus optional Buna-N®, polytetrafluoroethylene/Kalrez® or ethylene-propylene rubber seals.
- 3/8-inch NPT female in-line or rear connections, as well as 316 stainless steel floats.
- Availability of vertical in-line or panel-mount models.
- Suitability for research and development, pilot plant, and food and chemical processing applications.
