摘要： A passive device for detecting fluid flow in a pipe includes a housing, a mechanical couple for attaching the housing to at least one of the pipe and a structure disposed in close proximity to the pipe, and a chamber disposed within the housing such that the chamber is physically isolated from the pipe. The chamber is sized and shaped to receive a sound wave at a first end thereof and to amplify the sound wave between the first end and a second end of the chamber, the sound wave including a frequency range corresponding to that of a predetermined fluid flowing through an interior of the pipe. A sensor disposed at the second end of the chamber receives the sound wave amplified by the chamber, and communications circuitry is configured to send a signal corresponding to the sound wave received by the sensor to an external computing device.

摘要： Compliant leak detection system. The system includes structure adapted to support at least two rows of leak detection leaves, each leak detection leaf supported by an arm pivotally attached to the structure and urged outwardly by a torsion spring into contact with a pipe wall so as to adjust for changes in pipe diameter. The leak detection leaf includes a rigid support and a flexible member such that suction from a leak will cause the flexible member to contact the pipe wall and put a drag force on the structure. An axial force transmitting drum measures the drag force to indicate presence of a leak.

摘要： Technical solutions are described for determining topological connectivity between stations of a fluid-delivery pipeline network. An example method includes receiving temporal sensor measurements of the fluid-delivery pipeline network, that include a series of sensor measurements from each respective station of the fluid-delivery pipeline network. The method also includes generating a causality graph of the fluid-delivery pipeline network based on the temporal sensor measurements, where the causality graph includes a set of nodes and a set of links, where the nodes are representative of the stations, and a pair of nodes is connected by a link in response to the pair of stations being temporally dependent. The method also includes determining a topological network of the stations based on the causality graph, where the topological network identifies one or more destination stations for a supply station in the fluid-delivery pipeline network.

摘要： A non-invasive thermal dispersion flow meter with chronometric monitor for fluid leak detection includes a heater, an ambient temperature sensor and a flow rate sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. The fluid flow sensor is incorporated into a Wheatstone bridge circuit, which is used to provide increased sensitivity to the outputs of the sensors, Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. An alternative embodiment utilizes a single sensor and separate heater which work together to determine heat propagation times which in turn is used to calculate flow rate. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure.

摘要： According to some embodiments, a signal processing unit may receive distributed acoustic sensing data associated with a first set of a plurality of pipeline locations. The signal processing unit may also receive collected physical data representing a physical characteristic of a second set of a plurality of pipeline locations. The signal processing unit may then utilize a pipeline model having the distributed acoustic sensing data and collected physical data as inputs to automatically generate at least one alert indicating an increased probability of damage to the pipeline.

摘要： A method for diagnosing a leak of a fuel system in a vehicle is provided. The method includes determining whether an engine is actuated and a vehicle is thus driven as a monitoring condition for diagnosing the leak of the fuel system and determining whether an additional monitoring condition for monitoring an outflow of the fuel system is satisfied in response to determining that the engine is actuated and the internal pressure of a fuel tank included in the fuel system is less than a target value. The additional monitoring condition is a condition of preventing misdiagnosis of the leak in the fuel system due to disturbance while the vehicle is driven.
