Abstract
The measurement of flow is of paramount importance for the technological development and reliability of the industrial processes. Of the several quantities that are often measured, the flow is becoming more and more studied and researched, therefore, it needs several technological resources for its measurement. Currently, the technologies for the measurement of flows of single-phase fluids have great precision and repeatability and the phenomena that govern the interaction between fluid and meter are well understood. There are several flow meters for single phase flows, such as: orifice plate, nozzle, Venturi tube, ultrasonic, among others. In industries, especially in process and oil and gas industries, the flow model is typically multiphase, that is, there is the coexistence of two or more fluids within the piping that conditions it. The equipment used for multiphase flow flow measurement is quite complex and costly when compared to the one used in single phase flows. In this way, it is very interesting to adjust the typical single phase equipment to determine the flow rate. The measurement of flow from the generation of a differential pressure (depressions) is highly applied in the industries due to their low cost and applicability. In the present work, it was proposed the use of the correlation of Zhang et al. (1992) with the purpose of quantifying the value of the large flow in two-phase water-air flow. It was possible to observe the convergence between the values obtained with the Zhang correlation with the expected values.
