Abstract:

Pipeline-flow data is collected at a pipeline location and from time to time transferred to another location. A pair of controllers at the pipeline location autonomously cause the collected pipeline-flow data to be automatically transferred by a transceiver at predetermined times from the pipeline location to the other location and thereby enable the system to be powered by batteries on a low power budget. A first controller is adapted for providing an activation signal for turning on the second controller, and the second controller is adapted for turning off the second controller at predetermined times, for turning on and off the transceiver at predetermined times, and for instructing the first controller when next to provide the activation signal.
