Application of Oval Gear Flowmeters in Fuel Trade Measurement and Settlement

In fuel trade measurement and settlement, oval gear flowmeters are widely used due to their high accuracy, good repeatability, and immunity to fluid viscosity. As a type of positive displacement flowmeter, they measure the volume of fuel passing through precisely via the meshing rotation of a pair of oval gears, making them suitable for both dynamic and intermittent delivery scenarios of various fuels such as diesel, gasoline, and heavy oil. During custody transfer and financial settlement, the flowmeter can directly output volume pulse signals, which, when paired with an intelligent integrator, achieve highly accurate settlement data with errors typically controlled within ±0.2%. Furthermore, oval gear flowmeters feature a simple structure, oil resistance and corrosion resistance, and require no straight pipe runs, facilitating easy installation and maintenance in oil depots, gas stations, bunkering operations, and industrial furnace fuel supply systems, thereby providing reliable assurance for fair fuel trade and cost accounting.
