Series RSF Rotatable Scale Flowmeters
Dual, Rotatable Direct Reading Scales for Air and Water
The 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.
Note: If you require a calibration certificate with your flowmeter, please contact customer service to place your order.
