Fill-Level Measurement of Disinfectant Bottles with Ultrasonic Distance Sensors with Sound Conduction Thanks to a Soundpipe

In automated filling systems in the hygiene industry, bottles with disinfectant gel must be checked after filling to ensure that the correct filling level is present. For this purpose, an ultrasonic distance sensor is installed above the turntable with the individual plastic bottles. As the bottles have a narrow neck, the sensor requires sound conduction (soundpipe). This ensures that the sonic cone runs safely through the narrow opening. Thanks to ultrasound technology, colors, transparencies, reflection or degrees of gloss do not matter – all objects are reliably detected.
