GPI - Great Plains Industries FLOMEC OM Medium Capacity High Pressure Flow Meters Data Sheet
PRODUCT CONFIGURATION
OM SERIES MEDIUM CAPACITY HIGH PRESSURE
FLOMEC® OM Medium Capacity High Pressure Flow Meters
provide volumetric measurement of clean liquids for high pressure.
Suitable for applications including metering lubricants, chemicals,
grease, additives, and other high viscosity uids.
FEATURES / BENEFITS
• High accuracy and repeatability, direct volumetric reading
• No requirement for ow conditioning (straight pipe runs)
• Measures both high and low viscosity liquids
• Optional Exd I/IIB approval (ATEX, IECEx)
• High Pressure rated up to 5580 psi (400 bar) (4350 psi [300
bar] on 2 “ meter)
