Large Flow Positive Displacement Flow Meter System for Bulk Fuel and Oil Depot Applications
In bulk fuel terminals, oil depots, and large-scale fuel transfer operations, measuring equipment must do more than simply record volume. It must operate accurately, safely, and continuously under large flow and heavy-duty conditions. The M-150 Series Large Flow Positive Displacement Flow Meter System is developed specifically for these demanding environments.
This series is based on a proven positive displacement measuring principle, where liquid is measured in fixed internal volumes rather than calculated by velocity. As a result, measurement accuracy remains stable even during large flow transfer or fluctuating operating conditions. In global markets, this type of product is commonly known as a Large Flow Positive Displacement Meter in Europe and North America, a Bulk Fuel Meter in the Middle East and Africa, and a Oil Depot Flow Meter or Diesel Loading Meter in Southeast Asia and Latin America.
The M-150-A-1 model is engineered for large throughput applications, making it suitable for fast transfer between storage tanks and tanker trucks. It is widely used in bulk fuel handling, refined oil distribution centers, and industrial fuel supply systems, where reliability under large flow operation is essential.
Practical experience in international projects shows that large flow metering systems require effective inlet protection. For this reason, the meter is often installed together with the GLQ-150 Strainer with Air Eliminator, forming a complete metering solution. In many engineering specifications, such combinations are referred to as a Fuel Metering Skid or a Bulk Transfer Metering System.
The strainer does not function as a fine system filter, but as critical protection for the meter itself. During pipeline commissioning or continuous operation, welding residue, scale, or foreign particles may enter the flow stream. Installing a dedicated strainer upstream of the meter helps prevent internal damage, reduce downtime, and extend service life. This is why, even when a pump strainer is present, a separate meter strainer is still recommended in professional fuel systems.
The GLQ-150 strainer features a reinforced dual-layer screen design, where the outer layer provides structural support and the inner mesh captures contaminants. The integrated air eliminator reduces entrained air in the liquid, helping to maintain consistent measurement accuracy. In industry terminology, this unit is often called a Meter Protection Strainer or a Fuel Meter Air Eliminator.
From an application standpoint, the Large Flow PD Meter System is suitable for measuring diesel, gasoline, fuel oil, and other refined petroleum products. In North America and Europe, it is commonly used for bulk custody transfer in oil depots. In the Middle East, Africa, and Southeast Asia, it is widely applied in tanker loading and fuel redistribution projects.
Overall, the M-150 Series Large Flow Positive Displacement Flow Meter System is a professional solution designed for heavy-duty environments. Rather than focusing solely on measurement, it delivers a balanced combination of accuracy, durability, and system protection, making it well suited for global bulk fuel and oil transfer applications.
