摘要： A portable apparatus for measuring characteristics of hydraulic features in rivers and streams that are unwadeable. The apparatus consists of a tripod base, a horizontal boom that articulates on the tripod, a carriage configured to travel on the boom, and a measuring rod that can be moved vertically on the carriage. These components are designed to be portable, carried by hand or in a raft, and are adapted to be assembled on rugged terrain. The measuring rod is configured to accommodate sensors to measure characteristics such as channel topography, water surface topography, air-water mixing, velocity pressure differentials, and lift and drag forces. The apparatus can be adapted for measurement and monitoring in harsh environments such as volcanic lakes, fumaroles, and hot springs. The invention can be utilized for sampling air quality, weather, water quality, fluid mechanics (gas or liquid), soils, sediments, volcanic gases and hydrothermal fluids.

摘要： A pipeline inspection pig for locating crack-like defects (10) in pipeline walls (8) comprises at least one transmit transducer (T) for transmitting ultrasound energy into the pipeline wall (8), and at least one associated receive transducer (R) located adjacent the transmit transducer (T), the arrangement being such that, for a given defect (10) in the pipeline wall (8), ultrasound energy within the pipeline wall (8) is incident on the defect (10), part of said energy being reflected by the defect (10) back to the receive transducer (8) in the form of a first data stream, and the remainder of said energy passing through the defect (10) to be attenuated thereby and thence returned to the receive transducer (R) in the form of a second data stream, interpretation of the first and second data streams enabling the location of the defect (10) to be determined.

摘要： Ultrasonic pipeline inspection apparatus which utilises two different wave modes (e.g. a horizontally polarised shear mode and a symmetric Lamb wave mode) to discriminate different defect types by comparing corresponding signals collected from defects. EMATs may detect the signals. The detected amplitudes of the collected signals from both wave modes are compared to calculate a ratio, which may be compared with a distribution of ratio values for known defects to evaluate the type of defect detected. The apparatus may be a sensor module mountable on a pipeline vehicle and having a plurality of sensors distributed around its periphery.
