PRODUCT CONFIGURATION
OM SERIES LARGE CAPACITY (OVAL GEAR METERS)
The FLOMEC® OM Large Capacity Oval Gear Meters have tting
sizes of 3 inches and 4 inches, and handle volumetric ow measurement of clean liquids used in a wide range of applications.
FEATURES / BENEFITS
• High accuracy and repeatability, direct volumetric reading
• Measures high and low viscosity liquids
• Quadrature pulse output option and bi-directional ow
• Optional Exd I/IIB approval (ATEX, IECEx)
• No requirement for ow conditioning (straight pipe runs)
• Only two moving parts
