ABSTRACT:
A flow meter for measuring the flow in a dielectric pipe is disclosed. Two microwave signals are transmitted at measurement points via at least two transmitter antennae through the dielectric pipe and a flowing material. The distance between the measurement points is known. The signals that have passed through are received by receiver antennae and signal cross correlation is formed by a correlator, the flow rate being determined on the basis of the best correlation result. The measurement result is improved by filtering and/or directing the signals.
