Abstract

I en fremgangsmåte for å monitorere et fluid som strømmer i en rørledning, er det gitt en dynamisk modell for det strømmende fluidet. I det minste en operativ parameter danner del av den dynamiske modellen og er anordnet for måling. I det minste en sonarbasert sensor er koblet til rørledningen og er opererbar til å måle den operative parameteren. Denne sensoren er også opererbar til å generere signaler som indikerer den operative parameteren. En kontroller er i kommunikasjon med sensoren og er assosiert med den dynamiske modellen. Kontrolleren mottar signalene generert av sensoren, tolker og sammenligner disse signalene med den dynamiske modellen og bestemmer om den operative parameteren har avveket fra verdier som samsvarer med den operative parameteren som danner del av den dynamiske modellen. Den operative parameteren kan være en hastighet til lyd i fluidet som strømmer i rørledningen, trykk, temperatur, pumpehastighet, strømningsrate eller lignende.In a method for monitoring a fluid flowing in a pipeline, a dynamic model of the flowing fluid is provided. At least one operative parameter forms part of the dynamic model and is arranged for measurement. At least one sonar-based sensor is connected to the pipeline and is operable to measure the operational parameter. This sensor is also operable to generate signals indicating the operational parameter. A controller is in communication with the sensor and is associated with the dynamic model. The controller receives the signals generated by the sensor, interprets and compares these signals with the dynamic model and determines whether the operational parameter has deviated from values corresponding to the operational parameter forming part of the dynamic model. The operative parameter may be a velocity of sound in the fluid flowing in the pipeline, pressure, temperature, pump speed, flow rate or the like.
