Sensors for the measurement of advanced two-phase flow parameters (besides temperature and/or pressure) in production and transportation of oil and gas are required for monitoring and control purposes of plant and equipment. This requirement is also pushed by the current digitalization trend in industry, where sensors play a pivotal role as reliable source of data. This work presents a capacitive sensor system which can be applied in industrial environment at hazardous areas. The sensor was designed to comply with explosion safety standards whilst its electronics was developed in order to support network connections. Three pair of sensors were successfully installed in different positions of a 6-inch test facility of an oil company to monitor crude oil and natural gas two-phase flow evolution along the pipe.
