Ultrasonic sensors for oil pipeline monitoring

| Environmental Testing

A new range of piezoelectric based ultrasonic sensors have been released for high accuracy measurements in harsh environments for the oil and gas sector.

Morgan Advanced Materials has launched a new range of high-accuracy sensors for the oil & gas extraction sector, harnessing the unique capabilities of its proprietary piezoelectric materials which can provide reliable sensing and monitoring in high-temperature environments above 200C.

Suitable for applications from custody transfer to gas flow monitoring, the sensors from Morgan’s Technical Ceramics business draw on the proven properties of lead zirconate titanate (PZT).

With a compact footprint and boasting the extremely high sensitivity required, especially in natural gas applications, the sensors are capable of measuring both high and low flow to extreme accuracies.

Their ultrasonic nature also means they cope better with potential pressure drops than alternatives, such as turbine meters and electromagnetic meters.

Made from a selection of inert materials including titanium, alumina and zirconia, the new Morgan sensors also boast enhanced corrosion resistance when compared with conventional alternatives. This is particularly useful in harsh environments.

Charles Dowling of Morgan Advanced Materials explained: “Accurate sensing is key in the oil & gas sector for cost, environmental and safety reasons, but the high-temperature and highly corrosive environments experienced present a unique set of challenges for sensors.

“Some other ultrasonic sensors struggle to maintain accurate operation at temperatures above 200C – however, our piezoelectric materials have been proven to withstand continuous use at up to 250C with an intermittent maximum of 300C, providing peace of mind for specifiers seeking a reliable, accurate product. When their compact size and conductivity are also taken into account, they represent an attractive option for both custody transfer and flaring applications.”
