Oval Gear Meters
 

Oval Gear Meters are a member of the Positive displacement flow meter family.  They operate by repeatedly filling and emptying compartments of a known volume with a liquid. The flow rate is then calculated based on the number of times these compartments are filled and emptied.  Want to know more? Learn More...

Is an oval gear meter the best meter for my application?
 
Flow School - Oval Gear Meters Given their immunity to changes in viscosity, oval gear meters are ideally suited for measurement of viscous fluids or those with varying viscosities such as oils, syrups and fuels.  They're also well suited for low flow applications.  Because no straight pipe runs or flow conditioning are required, oval gear meters can be installed in tight areas where alternate technologies would fail.  Fluids should be clean and non-corrosive, preferably medium to high viscosity. 
Oval Gear Meters are generally not recommended for water or water-like fluids, because of the increased risk of fluid slippage between the gears and chamber walls.  The exception would be in low flow applications where a turbine meter would not be appropriate due to the low velocities.
 

Typical Oval Gear Applications

  • Lubricating Oil
  • Hi-Viscosity Fluids
  •  Greases
  • Epoxies
  • Polyurethane
  • Fuels
  • Solvents
  • Chemicals
  • Additives

Recommended Accessories - Oval Gear Meters

Oval Gear Meters work best with clean fluid, free of debris.  We carry Y-Strainers to fit all GPI Oval Gear Meters.   Strainers are available in sizes ranging from 1/4" to 2" and come complete with blow-off and plug. For information on available sizes, pricing, etc, Click Here or click the picture shown below.
