Scale Sensing Technology

ROTEC systems sense the buildup of local mineral scaling through ultrasonic detection. The technique is based on the change in the shape and arrival time of ultrasonic waves reflected by the surface in question. When the surface is covered in scales, the arrival time and shape of the reflected wave is changed. 


The ultrasonic sensor allows for the use of existing surfaces as the baseline for detecting changes. This makes the sensor quite sensitive to the initiation of scaling processes. Our algorithms detect scaling changes in real-time. One of the inherent advantages of ultrasonic sensors is that they are non-invasive.


Our detection systems can be applied to existing systems for detection of scaling in water treatment and process equipment such as pipelines, membrane modules, heat exchangers and cooling towers.
