Dwyer RSF021V | Rotatable Scale Flowmeter | 5 SCFM Air | 1.2 GPM Water
The RSF021V from Dwyer is a rotatable scale flowmeter whose full scale reaches 5 SCFM (140 SLPM) on air and 1.2 GPM (4 LPM) on water. Direct-reading graduations on a rotating tube shield remove the need for correlation charts on the RSF021V.
- RSF021V repeatability ±0.25% FS, accuracy ±7% FS
- Two 3/8 in female NPT connections on the RSF021V
- RSF021V pressure limit: 150 psig (10.34 bar) at 200 °F (93 °C), brass/SS
- Mount the RSF021V vertically or in a panel; turn-down 10:1
- The RSF021V carries 127 mm air and water scales

- Time is saved and a more precise reading is possible because to the 1.5 X magnification lens and reflective lens backdrop, which also lessen parallax and eye strain.
- Long operational life and a magnifying lens to improve reading resolution are features of the robust polycarbonate front cover, which also protects the tube from breaking.
- Added safety in the case of a breakage thanks to the safety blow-out rear panel that is incorporated.
