Product Overview

PLASTIC FLOWMETERS
Mount in any Position, Corrosive Resistant
DWYER INSTRUMENTS, INC. | dwyer-inst.com258
The Series HFPC & HFPS Plastic Flowmeters are a series of clear body, in-line
owmeters. This Series consists of the HFPC polycarbonate body owmeter and the
HFPS polysulfone body owmeter. These owmeters have dual scales measuring
both in GPM and LPM.
FEATURES/BENEFITS
• Clear body allows for visual inspection of the uid conditions and immediate problem
detection
• Reduce cost with multi position mounting to accommodate direction of ow
• Rugged construction allows for high pressure and temperature rating for long
operation life
• Injection molded, polycarbonate or polysulfone bodies yield great repeatability
APPLICATIONS
• Chemical processing
• Pulp and paper
• Process control
• Fluid power
• Hydraulic ow
• Heating loop ow
