Abstract
The present disclosure relates to a method and an apparatus for measuring a flow rate through a conduit, such as a pipeline. The method comprises providing a reference parameter, measuring a first parameter at a first position at the conduit and determining a difference between the first parameter and the reference parameter. The flow rate through the conduit is determined based on the difference between the first parameter and the reference parameter.
Claims14
