Title: The Role of the Oualator in Fluid Measurement Systems oualator

In precision industrial applications, the Oualator (often referred to in legacy documentation as a positive displacement flow meter) serves a critical function in monitoring viscous liquids. Unlike turbine meters that measure velocity, the Oualator operates by trapping specific volumes of fluid between interlocking oval-shaped gears.

As the liquid flows through the chamber, the pressure differential forces the paired rotors to turn. A sensor detects the non-contact rotation of these rotors, translating each cycle into a quantifiable pulse. This design offers two distinct advantages: high accuracy regardless of viscosity changes and a lack of required straight pipe runs upstream. Detect the LH surge

Maintenance protocols for the Oualator typically focus on the bearing surfaces and the gear coating. If the fluid contains abrasive particulates, the tight clearances of the Oualator can degrade, leading to "slippage" where fluid bypasses the measuring chamber. Regular calibration against a master meter is recommended to ensure volumetric integrity.
