Ultrasonic Metering in Intensive Care Devices
piezoceramic is able to detect sound waves and convert them into electrical signals. When positioned in a sound path oblique to the direction of flow, piezo components measure the sound propagation time in and [...] detectors for improved monitoring. They make use of the runtime measurement of the induced sound waves. If sound waves in a tube hit an air bubble, they are reflected at the interface of the bubble, since [...] increasing as well. Piezo technology offers various possibilities to improve them: Using piezo transducers, for example, makes intensive care devices such as infusion systems smarter and facilitates vital
