Detecting a break in the flow of liquids is critical in applications such as infusion pumps, hemodialysis, blood flow monitoring but also 3D-printing and food processing. Using state-of-the-art ultrasonic technology, the AD-102 sensor is capable of positively identifying troublesome air bubbles.

The compact AD-102 Air Bubble Detector (ABD) is used for non-invasive continuous monitoring of fluid for air bubble detection. The AD-102 can clearly detect even the smallest air bubbles of just 25% of the hose diameter and stop the supply within 0.5 ms.

The air bubble detector is available as standard for hose diameters of 6 mm. Versions for hose diameters from 3 mm to 10 mm are also available on request. This allows air bubbles with a volume of only 0.5 µl or 300 µm radius to be detected.
