SERIES IF
INDUSTRIAL DIRECT READING FLOWMETERS
Air/Water Direct Reading Scale, 304 SS Protective Shield
FLOW
The Series IF Industrial Direct Reading Flowmeters are owmeters that directly
measure ow rates up to 116 GPM (439 LPM) for water and 250 SCFM (7080 LPM)
for air service.
FEATURES/BENEFITS
• Direct read scales with no need for correlation charts saves time
• Detachable, clear 3/16˝ thick polycarbonate front shield provides protection at
maximum rated temperature and pressure
APPLICATIONS
• Gas or liquid metering
