OM Series Oval Gear Meters 

The FLOMEC® OM Series Oval Gear meters provide exceptional accuracy and repeatability in a wide range of applications measuring clean liquids.

Direct volumetric measurement from the positive displacement design gives you a flow measurement that is unaffected by changes in temperature, pressure, or viscosity – factors which can cause measurement errors in other flow meter technologies.

With a simple and reliable design concept using only two moving parts, they provide long service life and minimised maintenance costs.

Features & Benefits

  •  High accuracy and repeatability, measures every drop and saves waste in your process
  • Low pressure drop, minimising pumping costs
  • Extremely versatile design accurately measures high and low viscosity fluids
  • No requirement for flow conditioning (straight pipe runs) gives a simple and inexpensive installation
  • Only two moving parts provides a reliable product with minimal maintenance costs
  • IECEx/ATEX models available, making the product safe to use in flammable liquid applications

Sizes & Flowrates

OM004 | OM006 | OM008 - 1/8” – 3/8” (4mm-10mm) Pipe Sizes | Flows from 0.5L/hr – 550L/hr with Pulse-Out or LCD Display
OM015 | OM025 | OM040 | OM050 - 1/2” – 2” (15mm-50mm) Pipe Sizes | Flows from 1L/min – 450L/min with Pulse-Out or LCD display

The FLOMEC® Medium Capacity OM-Series Oval Gear meters are well suited to precise measurement of fuels, oils, solvents, alcohols, mildly aggressive chemicals, and various other clean industrial liquids. Flow rates from 1L/min to 450L/min, combined with low pressure drop, weights and measures (A/NZ only) and various hazardous area certifications make the medium capacity OM-Series meters well suited to almost any liquid transfer or dispensing application whether pumped or gravity-fed.  

OM Series Oval Gear flow meters are perfect for measuring the transfer of thick or non-conductive liquids.
