Bubble detection is critical in applications such as infusion pumps, hemodialysis and blood flow monitoring. TE Connectivity (TE) has developed a new compact AD-101 Air Bubble Detector (ABD) for non-invasive continuous monitoring of fluid for air bubble detection. Using ultrasonic technology, the AD-101 sensor is capable of positively identifying the presence of a break in flow of any type of liquid.

Detects bubble size as small as 70% of tubing inner diameter
Tubing outer diameters of 4mm and 6mm standard (sensor can be
customized to tubing outer diameters between 3 and 10 mm)
Non-invasive design eliminates sterility and fluid compatibility
concerns
High noise immunity to EMI/RFI
Acoustic coupling agent not required
Integral electronics
Power-on and continuous self-diagnostic tests to confirm
functionality
LED indication of sensor wet and dry state visible through housing
