ABSTRACT:
A method and an apparatus are provided for measuring the flow rate of a fluid in a duct, for example in an under-sea crude oil pipeline, in which samples of a radioactive tracer are injected, at intervals, into the duct and the passage of the samples of tracer detected by a scintillator. The tracer is generated by irradiating a large volume of a liquid obtained from the environment of the duct with a neutron source, so that the sample has been irradiated for a prolonged period prior to injection.
