TL;DR: In this article, a composite right/left-handed transmission line resonator was used to detect the velocity information and the material density from a single measurement, and the autocorrelation function was applied to the CRLH-resonator in order to detect velocity information.
Abstract: 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 autocorrelation function is applied to the CRLH-resonator in order to detect the velocity information and the material density from a single measurement. The areas of application of these sensors are gas/solids, gas/liquid and liquid/solids flows in various industrial applications.

TL;DR: The fluid sampler as discussed by the authors is used to sample gases in a collecting device and includes a flow control valve having a manually adjustable flow restricting orifice and a vacuum pump for drawing gas from the atmosphere through the collecting device.
Abstract: The fluid Sampler is used to sample gases in a collecting device and includes a flow control valve having a manually adjustable flow restricting orifice and a vacuum pump for drawing gas from the atmosphere through the collecting device and flow control valve to form therethrough a primary flow path. A flow controller is used to supply a supplemental flow of gas taken from the discharge end of the vacuum pump and supplied to the suction end of the vacuum pump in response to the differential in pressure across the flow control valve. The supplementary flow rate is automatically adjusted to maintain the differential in pressure constant.
