Ultrasonic Sensors for Liquid Level Detection in Containers
Ultrasonic Sensors for Liquid Level Detection in Containers
In industries such as pharmaceuticals, cosmetics, and beverages, the accuracy of liquid filling levels is critical. When filling liquids through small openings in bottles, test tubes, or pipelines, manufacturers require compact sensors capable of precise detection within confined spaces.
DADISICK's CSB12 series ultrasonic sensors are an ideal solution for such applications. With a thread diameter of just 12mm, these compact sensors are perfectly suited for liquid level control in containers with small openings. After the filling process, there is a brief pause in the system, during which the sensor accurately detects the liquid level. It can provide precise measurements or perform switching operations when the liquid level reaches the specified range. Thanks to its small design, the sensor can "listen" to the container from above. No additional auxiliary devices are required, and complex cleaning procedures are avoided. Bottles or pipelines are sealed only after the sensor confirms that the liquid level is within the acceptable range.
