Abstract
The invention discloses a method for electromagnetically measuring physical parameters of a pipe that includes measuring a pipe inner diameter ID and a pipe ratio of magnetic permeability to electrical conductivity μ2/σ2 by means of a measuring arrangement 1 comprising a transmitter coil 2 and a receiver coil 3, both coils being coaxial to and longitudinally spaced from each other, the measuring arrangement being adapted to be positioned into the pipe CS and displaced through the pipe.
