The intrinsically-safe sensor system also includes a memory component for storing the sensor data obtained from the sensors, a power source, a communication connection for communicably coupling the intrinsically-safe sensor system to a remote computing system, and a connector including internal and external connection regions for internally and/or externally connecting one or more additional devices to the intrinsically-safe sensor system on demand. The intrinsically-safe sensor system further includes an enclosure, as well as potting material for encapsulating an internal region of the intrinsically-safe sensor system that resides within the enclosure.

A nozzle cap includes a cap body defining a cap axis, the cap body defining a circumferential wall extending circumferentially around the cap axis; and a vibration sensor including a shaft, the shaft defining a first end and a second end, the first end attached to the circumferential wall, the cap axis positioned closer to the second end than to the first end.

A system and method of ultrasonic acoustic source location is provided. The method comprises receiving an ultrasonic acoustic signals at an ultrasonic detector having a multiple arrays. Each array comprising multiple transducers. The acoustic signals are pre-processed to triangulate a location of a source. Sensor data of a mobile device is associated with the determined location; and identify a location of the source on a display of the mobile device. The ultrasonic leak detector provides improved accuracy and performance efficiencies over traditional solutions.

A method of leak detection for oil and gas pipeline based on excitation response and system thereof includes: applying an active excitation signal (a pressure pulse directly input by human) or a passive excitation signal (a pressure fluctuation caused by opening and closing valves, etc.) to an oil and gas pipeline with existing leakage points, the excitation signal is reflected at the pipeline boundary and the leakage, and the reflected pressure wave continues to propagate to upstream and downstream, and finally is collected by the dynamic pressure transducer, then the existing leakage of the pipeline is detected and positioned by analyzing the transient response signal and the reflected pressure wave of leakage signal.

A fluid pipe 1 is monitored using a distributed acoustic sensing (DAS) fibre 10 provided within pipe 1. The DAS fibre 10 is coupled at one end to a light emitter 101 and a light detector 102. The light emitter 101 emits light pulses into the DAS fibre. The light detector 102 detects backscattered light so as to provide an indication of the vibration experienced by each section of the DAS fibre 10 and thus of vibration characteristic of particular pipe events including leaks of the pipe 1. The DAS fibre 10 in a pipe 1 can also be used to locate the route of a buried pipe 1 by successively tamping the ground surface at a number of locations A-E in the vicinity of the suspected route of the pipe 1 and comparing the tamping vibrations detected from each location A-E.
