Abstract
<B>PROCESSO DE MONITORAR FLUXO DE FLUIDO TRIFáSICO EM TUBULARES<D>. Fluxo de fluido multifásico em uma tubulação ou outro conduto de fluxo é monitorado utilizando uma combinação de detectores do tipo de fluxo. Um conjunto de detectores monitora as interfaces entre interfaces de fluido e o outro monitora a presença de diferentes fases de fluido em torno da periferia do conduto de fluxo. As taxas de fluxo de fluido volumétrico relativas podem ser medidas detectando mudanças nas interfaces de fase entre dois conjuntos de anéis sensores utilizando sensores espaçados em torno do conduto de fluxo com o tipo de fluxo de fluido sendo detectado através do conduto de fluxo com um detector de capacitância anular. Os anéis sensores utilizam, tipicamente, transdutores ultra-sónicos para detectar as interfaces de fase enquanto o dispositivo de capacitância indica a presença (ou ausência) de fases diferentes em torno da periferia do conduto de fluxo. Combinando as saídas dos detectores diferentes, uma indicação dos fenómenos de fluxo no conduto de fluxo pode ser obtida. A taxa de fluxo no conduto pode ser medida diretamente utilizando um conjunto concentricamente orientado de anemómetros de fios quentes ou um conjunto concentricamente orientado de termopilhas espaçadas igualmente em torno do conduto de fluxo em combinação com o dispositivo de capacitância anular.<B> PROCESS OF MONITORING FLOW OF THREE-PHASE FLUID IN TUBULARS <D>. Flow of multiphase fluid in a pipe or other flow conduit is monitored using a combination of flow type detectors. One set of detectors monitors the interfaces between fluid interfaces and the other monitors the presence of different fluid phases around the periphery of the flow conduit. Relative volumetric fluid flow rates can be measured by detecting changes in the phase interfaces between two sets of sensor rings using sensors spaced around the flow duct with the type of fluid flow being detected through the flow duct with a flow detector. annular capacitance. Sensor rings typically use ultrasonic transducers to detect phase interfaces while the capacitance device indicates the presence (or absence) of different phases around the periphery of the flow conduit. By combining the outputs of the different detectors, an indication of the flow phenomena in the flow conduit can be obtained. The flow rate in the conduit can be measured directly using a concentrically oriented set of hot wire anemometers or a concentrically oriented set of thermopiles equally spaced around the flow conduit in combination with the annular capacitance device.
