OGM-II High-Precision Oval Gear Flow Meter – Industrial Liquid Measurement

OGM-II High-Precision Oval Gear Flow Meter – Industrial Liquid Measurement

The OGM-II Series Oval Gear Flow Meters is engineered for high-precision liquid measurement across a variety of industrial applications. Suitable for fuels, lubricants, and other clean process fluids, these meters maintain exceptional repeatability and durability even when measuring liquids of different viscosities. The compact design combined with low pressure drop makes them ideal for limited-space piping systems and mobile equipment, ensuring accurate and reliable measurement every time.

Constructed with high-strength aluminum, the OGM-II meters feature a simple and robust structure that minimizes maintenance requirements. The meters can be installed horizontally or vertically to accommodate diverse operational setups. Optional pulser output allows real-time transmission of flow data to pumps, controllers, or data acquisition systems, enabling automation and intelligent monitoring. The OGM-II meters are compatible with fueling nozzles, small transfer devices, and on-site measurement systems, providing flexible installation solutions.

Around the world, this type of oval gear meter is known by various names: in North America and Europe, it is commonly referred to as an Oval Gear Flow Meter; in Latin America as Medidor de Engranaje Oval; in French-speaking regions as Compteur à Roue Oval; in Germany and German-speaking areas as Ovale Zahnrad Durchflussmesser; and in the Asia-Pacific region, often as a pulse-output oval gear flow meter. These diverse designations reflect its widespread use and acceptance in global liquid measurement markets.

The OGM-II Series excels in fuel distribution, industrial lubricant handling, and other fluid monitoring applications. It ensures precise fuel delivery at gas stations or in tank trucks, accurate lubricant measurement in industrial processes, and seamless integration with automated pumps and control systems for smart operations and data tracking. Its compact size also makes it suitable for mobile equipment and small-scale measurement systems where space is limited.

Key advantages of the OGM-II meters include high measurement accuracy, flexible installation, and low maintenance cost. With ±0.5% accuracy, it provides reliable and repeatable data for process control. The optional pulser output enables automatic start and stop of connected pumps, while the low pressure drop design minimizes system resistance. The simple mechanical design, with minimal moving parts, further enhances ease of maintenance and long-term reliability.

In summary, the OGM-II High-Precision Oval Gear Flow Meter combines compact design, high accuracy, automation compatibility, and robust durability, making it an ideal choice for industrial liquid measurement and control. Whether in fuel transfer, lubricant management, or automated process monitoring, this series delivers stable performance and trusted measurement results recognized worldwide.
