OM SERIES CHEMICAL FLOW METER
The FLOMEC® Chemical Flow Meter provides precise volumetric
ow measurement of a broad range of clean water based products
and aggressive chemicals and is also suitable for most fuels, fuel
oils and lubricating liquids. Applications include batching, dosing
or packaging of various corrosive chemicals as a more economical
alternative to a complete 316 stainless steel meter for liquids such
as Diesel Exhaust Fluid (Adblue).
FEATURES / BENEFITS
• High accuracy & repeatability, direct reading ow meter
• No requirement for ow conditioning (straight pipe runs)
• Measures high & low viscosity liquids
• Quadrature pulse output option & bi-directional ow
• Optional NMI Pattern Approval (Australia Only)

METER SELECTION
• PPS meters are used for non-aromatic/non-halogenated organic
chemicals, water based liquids, Diesel Exhaust Fluid and petro-
leum products including oils and grease, fuels and fuel oils. It is
unsuitable for strong acids and oxidizers.
• PPS meters with standard ceramic rotor pins are suitable for ap-
plications where stainless steel is not suited or permitted.
• Blind pulse meters are available with Reed Switch and Hall Ef-
fect outputs. Quadrature pulse and integral 4-20mA outputs are
optional.
