Abstract

This paper presents an application of a Composite Right/Left-Handed (CRLH) Transmission Line resonator for a compact mass flow detector with increased sensitivity compared to a conventional microwave mass flow detector. In this concept series capacitors and shunt inductors are used to synthesize a medium with simultaneously negative permeability and permittivity - the so called metamaterial.
The helix shaped distribution of the plates in the cylindrical CRLH-TL sensor offers the possibility to detect flow inhomogeneities within the cross-section of the pipeline that can be applied to increase the accuracy of the detector. A prototype was realized and tested in a dedicated measurement setup to prove the concept.
