Abstract: A flow metering system is generally presented herein. The flow metering system is generally configured to measure liquid flow from a liquid dispensing system and to track volume change and other measurable characteristics of the liquid in real time. The flow metering system may include a flow sensor. The flow sensor may be positioned in line with a liquid flow line, or in a separate line where the remainder of the liquid exits via a bypass, where the liquid flow line is connected to and configured to dispense liquid from a pre-packaged liquid volume, or a reservoir. For example, the flow sensor may be connected in-line to a beer line, such as vinyl piping, for a beer keg or soda dispensing tank. However, it will be appreciated that the flow metering system may be used with any type of liquid dispensing system.

Abstract: A method and system are provided for anomaly detection in energy systems. Non-contact sensing of an energy system based on electric and magnetic fields uses non-contact electric- and magnetic-field sensors to produce electric- and magnetic-field signals. The electric and magnetic field signals are filtered to remove noise. Features are extracted and normalized from the magnetic and electric field signals to characterize parameters of each signal. Density-based spatial clustering of extracted features is performed using a selected minimum number of points required to form a cluster and a parameter indicating the distance within which data are considered to fall within the cluster. An anomaly is determined from data point(s) that do not fall within the cluster formed by data points in normal operation. The density-based spatial clustering of extracted features may be performed using a Density-Based Spatial Clustering of Application with Noise (DBSCAN) algorithm. Features may be extracted using Fourier analysis.

The laser beam may also be defocused by passing it through a pinhole.
