Contactless and Contamination-Free Measuring with Ultrasound

Ultrasound has been used to realize fluid 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 fluid 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.

PI supports you with piezo solutions for applications such as:

Fluid metering
Air bubble detection
Level detection
Leakage detection
Completely Contactless Monitoring of Liquids and Gases
Completely Contactless Monitoring of Liquids and Gases
Fully automated flow measurement or air bubble detection is the basis of many industrial systems in which liquids are moved and need to be monitored. Whether in consumer- or large-scale water meters, gas flow measurement in pipelines or air bubble detection in plants of the food or pharma industry – ultrasound can detect the flow of various media contactlessly and thus without any contamination.
