Series RSF Rotatable Scale Flowmeter
Brand: Dwyer Instruments, LLCThe Series RSF Rotatable Scale Flowmeters are ideal for the direct flow measurement of air, water, and other commonly used gases.
These flowmeters are designed with direct read scales with no need for correlation charts and graduations are marked on a rotating, polycarbonate tube shield.
They feature borosilicate glass tubes with brass and SS metering valve options.
Features- Reflective lens background and 1.5 X magnification lens reduces parallax and eye fatigue saving time and allowing for a more accurate reading
- Long operating life with thick polycarbonate front shield that protects tube from breakage and serves as a magnifying lens to enhance reading resolution
- Increased protection with included safety blow-out back panel for added safety in the event of breakage
