For the detection of cracks and corrosion in pipelines an ultrasonic measuring system (pig) was developed. During the pipeline inspection there is no communication to the outside world, the accumulated data have to be stored on a mass storage device.…
Oil sludge presents a harmful but economically valuable waste. A large amount of oil sludge is produced during the processes of extraction, refining, storage, and transportation of petroleum. The contents of oil, water, and slag in the oil sludge are…
This work deals with the development of an ultrasonic backscattering sensor for the monitoring of water-in-oil emulsion. The sensor consists of a 3.5-MHz ultrasonic transducer, working in pulse-echo mode, and an array of cylindrical obstacles located…

In mineral transportations, it is essential to measure the gas hydrate particle concentration to manage the risk of flowline blockage. Traditional single-frequency ultrasonic methods measure the particle concentration by treating the mixtures with an…
Oil volume fraction determination is important for the transportation and separation of oil–water dispersed flow in petroleum industry, for which ultrasound method is suitable with the advantages of good penetration and low cost. The existing…
At present, there are few high precision and inexpensive equipments for measuring the water content of petroleum (MMCP), which is a big problem faced by most of the operators. The sonic velocity is determined by the fluid property. So the different…
