Ultrasonic
Sound-based measurement without intrusion
ULTRASONICUltrasonic
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
Ultrasonic Product Families
All products
Bubble & Air Detection
Non-contact ultrasonic bubble sensors for detecting air emboli in IV lines, infusion pumps, and dialysis circuits. Clamp-on designs require no fluid contact.
Liquid Level — Ultrasonic
Clamp-on ultrasonic level sensors detect fluid presence through vessel walls with no penetration, ports, or sealing requirements.
