Contactless and Contamination-Free Measuring with Ultrasound
Ultrasound has been used to realize flow metering for many years – be it in pipelines, tanks, silos, or even in water meters. Automated process monitoring is one of the most important applications of flow metering in the industry – measuring must be quick, precise, safe, and maintenance-free therefore ensuring product quality and throughput, e.g., in production lines or industrial plants. In addition to fluids, often air bubbles are detected in tubes of industrial plants.
In order to carry out ultrasonic measurements, sensors are applied to the tube or pipe, mostly on the outside, and sound impulses penetrate into it. Ultrasound can recognize the flow of various media contactlessly and without contamination.
With piezo technology these ultrasonic sensors can work reliably and save energy – piezo-ceramic components offer the best conditions to generate and detect ultrasonic waves.
PI offers customer-specific piezo ultrasonic transducers that can be integrated in ultrasonic sensors. Thanks to its longstanding experience in piezo technology, PI can also offer assembly to its customers, for example, gluing or soldering of the piezo elements as well as a higher refinement, such as contacting with flexible printed circuits.
