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
