  • Base gauge and multiple remote sensors
    Patent number: 10329894
    Abstract: A system for monitoring one or more downhole parameters. The system includes a downhole base gauge configured to receive power from a surface power drive and to communicate data with a surface computing device and a plurality of downhole remote sensors coupled to the base gauge in series and configured to generate data indicative of one or more observable parameters. The base gauge is further configured to query one of the remote sensors and, in response to such a query, the remote sensor is configured to transmit data indicative of the observable parameter associated with that sensor to the base gauge.
