• •For the first time a novel design of Wire-Mesh Sensor for industrial application is presented.•Phase fraction information about the flow are provided in almost real time.•Key parameters are obtained from Wire-Mesh Sensor data describing the flow pattern of vertical upwards gas–liquid flow.•A flow regime identification algorithm, enabling also identification of transition regions for vertical upward gas–liquid pipe flow is presented. Wire-Mesh Sensors (WMS) are applied in many research applications to determine the distribution of the phase fraction and to visualize the flow behavior within a pipe. However, their application in industries is restricted due to the procedure of data acquisition and offline post processing. Here a new design of Wire-Mesh Sensor for monitoring void fraction and flow pattern behavior is presented. As result of online data evaluation cross-sectional void fraction information is provided in almost real-time. Additionally, the present flow pattern is determined by statistical analysis of recorded data of a time period of 10s. This is the first time a Wire-Mesh Sensor was used for this purpose. With the help of fuzzy methodology a distinction of the four main flow patterns of vertical upward gas-liquid flow is possible. Furthermore, transition regions can be identified. The algorithm is based on the evaluation of statistical void fraction distribution as result of Wire-Mesh Sensor data. Validation experiments of the new adopted algorithms are carried out in a 50mm-ID two-phase air-water flow-loop at Tulsa University Horizontal Well and Artificial Lift Projects (TUHWALP).
