OM SERIES MEDIUM CAPACITY (OVAL GEAR METERS)

The FLOMEC® OM Medium Capacity Meters are great for medium
ow ranges and have the ability to handle a wide range of uid
viscosities.

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
