Dwyer RSF121V | Rotatable Scale Flowmeter | Air to 5 SCFM, Water to 1.2 GPM
For direct-reading flow measurement of air (to 5 SCFM (140 SLPM)) and water (to 1.2 GPM (4 LPM)), Dwyer offers the RSF121V rotatable scale flowmeter. Scale marks on the turning polycarbonate shield of the RSF121V let operators read air, water and other frequently used gases without correlation charts.
- 10:1 turn-down and 127 mm direct-reading scales on the RSF121V
- Two 3/8" female NPT connections; vertical or panel mounting for the RSF121V
- RSF121V flowtube: borosilicate glass; brass/SS versions rated 150 psig (10.34 bar) at 93°C
- RSF121V full-scale capacity: 5 SCFM (140 SLPM) air, 1.2 GPM (4 LPM) water
- Accuracy ±7% FS with ±0.25% FS repeatability on the RSF121V

- 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.
