A particulates mass flow meter has been developed using a composite right/left-handed transmission line resonator. The presented sensor principle promises the possibility to design precise particulate solids mass flow meter with moderate costs. The Spatial Filter Velocimetry is applied to the sensor in order to detect the velocity information. The simultaneous detection of the velocity and the solids/air concentration from a single measurement, ensure a true mass flow detector. The detector offers good prospects for industrial applications with various scenarios of gas/solids, gas/liquid and liquid/solids flows.Index Terms-Composite right/left-handed metamaterial, permittivity measurement, pneumatic conveying, spatial filtering velocimetry, transducers, mass flow meters.

This paper is focused on the application of concepts derived from metamaterials to the development of novel devices, circuits, and antennas of interest in wireless communications, radiofrequency identification (RFID), and sensors. Specifically, it is shown that artificial transmission lines based (or inspired) on metamaterials exhibit interesting properties, useful for the implementation of high-performance and compact devices as well as novel functional devices. Thanks to the presence of reactive loading elements in such artificial lines, the main line parameters, that is, the characteristic impedance and the phase constant, can be engineered. This has opened new paths for RF and microwave circuit and antenna design on the basis of impedance and dispersion engineering.

A novel moisture insensitive mass flow detector based on a mass flow sensor with open an cylindrical resonator is presented in this paper. The mass flow sensor consists of two MicroStrip Patch couplers integrated in a Composite Right-/Lefthanded Transmission line resonator. The design of a particulate mass flow detector based on this sensor is given and the algorithm to detect the average solids concentration is shown. The simultaneous detection of the velocity and the moisture independent solids/air concentration from a single measurement, ensures a true mass flow detector. Since it was already shown formerly, both sensor principles are able to measure the moisture dependent mass flow rate with high precision, we expect for the combination of both principles a detection accuracy in the range of both single sensor principles. Measurements of natural substance granulate with different amounts of moisture up to 18% (vol.) were done. The rearrangement of the CRLH-TL resonator to a helix shape opens the possibility to detect of the cross-sectional flow distribution of the fed material. Simulations and measurements of a helix shaped CRLH-TL resonator were done in order to proof the concept. The novel detector design is promising for industrial applications with various scenarios of gas/solids, gas/liquid and liquid/solids flows.
