Dwyer Instruments RSF111V | Rotatable scale flowmeter | Max. flow rate 5 SCFM (140 SLPM) air | 1.2 GPM (4 LPM) water
Air, water, and other frequently used gases may all be directly measured by using the Model RSF111V Rotatable Scale Flowmeters. These flowmeters have graduations written on a spinning polycarbonate tube shield, and their direct read scales eliminate the need for correlation charts. They have brass and stainless steel borosilicate glass tubes with choices for SS metering valves.

- 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.
