2. Positive Displacement Flow Meters for Heavy Oils Oval Gears Meters

3. Introduction Principle of Operation Aplications Experience in Heavy Oils New Design Oval Gears Meters

4. ODC Series – Double Case Oval Gears Meters

5. INNER MECHANISM HOUSING Avoid Pipeline Movemnt Influence Avoid Pressure Influence on the Measurement Better Thermal Stability

6. Oval Gears Meters – Principle of Operation Torque on arm A > Torque on arm B

7. Standard Tooth Profile Clean Liquids Low Viscosity Applications  Considerable Pressure Loss

8. Standard Tooth Profile  Limited Space Between Teeth  Higher Sealing Properties

9. Standard Tooth Profile  Developed for Liquids Without Solids  Lower Viscosities Require More Sealing Points

10. Special Tooth Profile High Viscosity More Solids Tolerance Lower Pressure Loss Material: CF8M

11. Special Tooth Profile More Space Between Teeth Less Number of Teeth

12. Special Tooth Profile More Space to Handle Solids Higher Viscosities

13. Standard Tooth Profile x Special Tooth Profile x

14. Special Tooth Profile  Wear with Solids  Less Time Between Failure

15. New Special Tooth Profile Development Higher Mechanical Resistance Longer Working Life New Material: ASTM A747 New Special Tooth Profile
