The oil and gas industry is one of those that use the product the most, due to the principle of differential pressure flow measurement, especially in the measurement of natural gas, due to its low cost, simplicity of installation and high accuracy, always in accordance with recognized standards (AGA or ISO) for this type of application.
The main and most traditional representative of this category of measuring elements is the orifice plate, which, like the other elements for this principle, generates a differential pressure through the measuring element proportional to the flow.
The other representatives of this class of meters are Metrocones, integral orifices, flow nozzles and Venturi tubes. With the exception of Metrocones, these differential pressure measurement elements require the installation of flow straighteners to provide an adequate flow profile, thus ensuring a perfect measurement.
