DK-SA 840 Pipe Thickness Monitor
Overview
The Duke Non-intrusive Acoustic Pipe Thickness monitor provides real-time monitoring solutions for corrosion/erosion in pipelines. It integrates mature ultrasonic pipe thickness monitoring sensors(single point/phased array), advanced real-time data transmission hardware, and Duke’s data visualization suite, delivering highly accurate and repeatable measurements of pipe thickness, metal loss, and corrosion/erosion monitoring. This system is an important tool for studying metal corrosion/erosion rates and mechanisms, providing reliable data for the selection of corrosion/erosion prevention processes.
Based on echo sensing technology, the Duke Non-intrusive acoustic pipe thickness monitor uses high-frequency sound waves generated by piezoelectric transducers to pass through materials. It measures the time for echoes to return to the sensor or records the amplitude of sound waves when resonance occurs as signals to detect defects or measure absolute pipe thickness, rather than average or extrapolated values. It can identify corrosion/erosion activities at an early stage, allowing for continuous monitoring in high-risk areas and providing accurate and repeatable results.
