Ultrasonic

Sound-based measurement without intrusion

Ultrasonic technology uses high-frequency sound waves — typically above 20 kHz — to detect, measure, and analyze targets without physical contact. SMD's ultrasonic sensors are engineered for demanding medical, industrial, and fluid management applications, offering non-invasive measurement that preserves both the sensing element and the measured medium.

Key Benefits

  • Zero contact with the measured fluid
  • Works through tube or vessel walls
  • No contamination risk — ideal for sterile processes
  • Detects bubbles as small as 0.1 µL
  • Suitable for any liquid or slurry
