OGM Series of Oval Gear Flow Meters

The OGM Series Oval Gear Flow Meters are high-accuracy, high-reliability positive displacement flow measurement devices, widely used for metering and controlling petroleum products, fuels, diesel, lubricating oils, chemical liquids, solvents, and other low to high viscosity fluids.

This product range includes mechanical display models, electronic display models, electronic preset flow meters, and pulse output versions, with housing materials available in aluminum alloy, stainless steel, and engineering plastics, meeting diverse application, budget, and automation requirements.

1. Working Principle and Design Features

The OGM Series flow meters operate based on the oval gear positive displacement measuring principle. As liquid flows through the metering chamber, it drives a pair of precisely machined oval gears to rotate synchronously. Each rotation corresponds to a fixed volume of fluid, which is measured through mechanical counting or electronic signal conversion, ensuring stable and highly repeatable volumetric measurement.

Key Advantages

High accuracy independent of flow velocity

Excellent performance at low flow rates

Ideal for high-viscosity fluids such as lubricating oil and heavy oil

Low pressure loss

Minimal straight pipe length requirement

Compact structure and flexible installation

Stable operation with long service life
