OM Series Small Capacity Flow Meter

OM Series Small Capacity Flow Meter


The FLOMEC® Small Capacity OM Series Oval Gear meters are well suited to measurement of very low flow rates of various additives, chemicals, fuels, lubricants, and purified waters. Exceptional accuracy and reliability can be obtained on clean liquids of almost any viscosity.

A variety of materials for the body, rotors, seals, process connections and integral options allow for an extremely versatile application range.


  • Flows from 0.5L/hr – 550L/hr with Pulse-Out or LCD Display
  • Sizes 1/8” – 3/8” (4mm-10mm) Pipe Sizes
  • High accuracy and repeatability, direct volumetric reading
  • Measures high and low viscosity liquids
  • No requirement for flow conditioning (straight pipe runs)
  • Stainless Steel rotors (Optional PPS rotor for OM008 meter only)
  • Quadrature pulse output option and bi-directional flow
  • Optional Exd I/IIB approval (ATEX, IECEx)
  • Only two moving parts(Average 5 year use)
  • Factory calibrated (not field calibratable)


  • Fuel additive injection
  • Fuel consumption measurements
  • Water treatment chemical dosing (flocculants, surfactants, biocides, etc.)
  • Corrosion inhibitor dosing
  • Demineralised / RO water dosing or dispensing
  • Monitoring of oil or grease lubricants

Use the filters to configure the meter to your required specifications.
