摘要： Pipeline networks are ubiquitous for transporting fluids. Failure modes may result in a wide spectrum of negative effects ranging from energy loss to revenue loss to catastrophic failure with loss of life. The present invention introduces innovative technology to detect, identify and locate events representing failure modes and/or precursors to failure modes within a pipeline network. The present invention addresses the issues with the prior art based on the following innovations—exploiting the signal processing enabled by detecting the passive acoustic signal in conjunction with both an active reflected acoustic signal and an active transmittive acoustic signal within a pipeline segment. These measurements can be aggregated to reduce the effects of ambient noise and improve the invention's ability to detect, identify and locate anomalous events representing failure modes and/or precursors to failure modes within a pipeline network.

摘要： A system and method for detecting a leak in a hose of a hydraulic system having a control valve assembly with first and second work ports in fluid communication with an actuator is disclosed. In one aspect, the method includes estimating a first hydraulic fluid flow rate for fluid flowing from the control valve assembly first work port to the actuator. Another step may be estimating a second hydraulic fluid flow rate for fluid flowing from the actuator to the control valve assembly second work port. In one step, a proportional flow rate difference is calculated between the first and second hydraulic fluid flow rates. Subsequently, a flow error value can be calculated by subtracting the flow rate difference from a predetermined margin value. Where the flow error value integrated over time exceeds a total flow error threshold value, a hydraulic fluid leak signal can be generated.

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.

摘要： Fluid leaks are identified and located by successively monitoring changes in fluid flow and sound velocities of fluid at a plurality of locations in the pipe with flow meters, such as with ultrasonic flow meters. Preferably the successive monitoring sampling rates are sufficiently high to measure instantaneous velocity changes. A controller coupled to the meters associates changes in monitored fluid flow and sound velocities in two locations along the pipe with a leak event occurring between those locations. The controller identifies the association event at each location and correlates pipe leak location based at least in part on difference in time between the respective location events. The system and method may be used in liquid and gas pipeline transmission systems.
