FIELD: measurement equipment.
SUBSTANCE: method includes measurement of intrachannel pressure at serially arranged pipeline sections and correlation treatment of produced data for detection and localisation of a leak. Besides, prior to correlation treatment of data from at least one measured value of the pressure they directly subtract the component of the measurement signal specified by action of the pump equipment.
EFFECT: improved selectivity of control to leaks on pipelines with pump supply of transported medium.
