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


  • Detects bubble size as small as 1uL
  • Sensor can be customized to fit tube or pipe
  • Size from 0.5 mm to 100 mm
  • Non-invasive design eliminates sterility and fluid compatibility concerns
  • High noise mmunity to EMI/RFI
  • Acoustic coupling agent not required
  • Integral Electronics


  • Infusion Pump
  • Apheresis / Auto-transfusion
  • Biotech / DNA Analysis
  • Blood Processing
  • Immunoassay
  • Chemical Analysis
  • Hemodialysis
  • IN-VIVO Detection of Gas
