The digital oval gear diesel oil flow meter is a precision-engineered measuring instrument designed for accurate monitoring of diesel fuel, light oils, and other compatible fluids. It uses positive displacement oval gear technology to ensure high accuracy and repeatable performance, even with varying viscosities. This type of flow meter is commonly used in fuel dispensing systems, mobile refueling units, agricultural machinery, generators, and oil storage systems.

It features a compact and durable housing, an easy-to-read digital LCD display, and is available in multiple material and connection configurations to suit different installation environments. With options for pulse output and battery or external power supply, this flow meter can be integrated into both standalone and automated systems.
