Oval Gear Flow Meter Overview

Oval Gear Flow Meters can be used in a wide range of media applications and are designed for clean process fluids. No flow conditioning allows for superior design flexibility. Maintenance is minimal and changing viscosities do not affect meter accuracy. Cost of ownership can be very attractive compared to other flow technologies while providing highly accurate and repeatable results. Oval Gear Meters are mechanical meters and should not be used in fluids with non-soluble particulate. This is a liquids only meter – gases are not suitable. Water like applications should always be reviewed by a qualified Oval Gear Flow Meter Manufacturer.
