Abstract

Den foreliggende oppfinnelse angår en fremgangsmåte og en anordning for operasjon av et kontrollsystem for en plugg eller elementer i en plugg, i en rørledning, hvor anordninger for aktuering av en anordning av kontrollsystemet, leser trykket i det eksterne fluidet rundt pluggen, ved høytrykkssiden av pluggen, og et gitt trykk aktiverer anordningen.The present invention relates to a method and a device for operating a control system for a plug or elements in a plug, in a pipeline, where devices for actuating a device of the control system read the pressure in the external fluid around the plug, at the high pressure side of the plug. , and a given pressure activates the device.
