METHOD FOR REMOTE CONTROL OF FLOW CONDUCTORS Russian patent published in 2010 - IPC E21B47/12 

FIELD: measurement equipment.

SUBSTANCE: invention relates to remote control of flow conductors, in particular, to system of autonomous metering stations for measurement of flow conductor parametres of interest. System for detection of at least one parametre of interest related to flow conductor with a flow of fluid medium moving in it comprises flow conductor made of composite material, at least one conductor included into composite material and several metering stations. Conductor is arranged along with flow conductor length and is able to transmit and receive radio frequency signals. Metering stations are arranged in specified areas at a distance from each other along flow conductor length. Besides each of stations is able to receive the first signal sent by at least one specified conductor, and to send the second signal related to measurement of at least one parametre of interest in response.

EFFECT: improved efficiency of control of flow conductor parametres of interest without application of additional power supply and signal lines.
