Abstract: Fluid leak observations made by different types of sensors are collected by an edge device. The edge device generates a graph model to represent the fluid leak observations made by different types of sensors. The graph model is provided by the edge device to a remote device for fluid leak detection at the fluid facility.

Abstract: Fluid leak observations made by different types of sensors are combined to detect fluid leaks at a fluid facility. Separate fluid leak observations made by different types of sensors are reconciled using a Bayesian model. The Bayesian model outputs likelihoods of different fluid leak probabilities, and the likelihoods of different fluid leak probabilities are used to facilitate operations at the fluid facility.

Abstract: Infrared images of a fluid facility are captured to detect, localize, and quantify fluid leaks with confidence at the fluid facility. Changes in pixel values for a fluid leak, which reflect changes in temperature due to the fluid leak, are used to quantify the fluid leak. The location of the fluid leak is identified using the setup of the infrared camera and the fluid leak captured within the infrared images. A dispersion of the fluid leak is calculated and presented to show the path of the fluid leak.
