A leak detection sensor may be capable of dynamically adjusting a sampling time for acoustic data based on monitored fluid flow. The leak detection sensor monitors leak detection information associated with a fluid in a fluid transporting medium over a predetermined time interval, where the leak detection information comprises flow and pressure of the fluid in the fluid transporting medium, and processing the leak detection data monitored at the sampling time in the predetermined time interval, where the sampling time is determined based at least in part on the monitored flow of the fluid.

Coordinated acoustic leak detection sensor sampling

Methods and apparatus to detect leaks based on temperature data are disclosed. A disclosed apparatus includes a storage device to store spectral recording data associated with spectral recordings measured by an acoustic sensor of a node of a utility distribution system, and temperature data associated with the utility distribution system. The disclosed apparatus also includes a processor to select a portion of the spectral recording data based on the temperature data, where the processor is to generate a data packet based on the portion, and a transceiver to transmit the data packet.

Methods and apparatus to detect leaks based on temperature data

Methods and apparatus to analyze sensor recordings are disclosed. An example apparatus includes a sensor to record a plurality of recordings and a memory. The example apparatus also includes a processor to convert one or more of the plurality of recordings to corresponding spectral representations where the at least two recordings are separated by a time gap, calculate a spectral average based, at least in part, on the spectral representations, store the spectral average to the memory, and generate a data packet based, at least in part, on the spectral average. The example apparatus also includes a transceiver to transmit the data packet to another device to compare the spectral average to a baseline spectral average to determine a system condition.

Sensor recording analysis apparatus and method

Methods and apparatus to detect leaks are disclosed. A disclosed leak probability analysis apparatus associated with a utility distribution system having sensors includes a receiver to receive spectral recording data associated with spectral recordings measured at the sensors, and a storage device to store the spectral recording data. The leak probability analysis apparatus also includes a processor to calculate spectral energies associated with the spectral recording data, calculate deviations of the spectral energies, normalize the spectral energies based on the respective deviations, and generate a leak probability distribution of the utility distribution system based on the normalized spectral energies.
