Ultrasonic sensor AFEs
Ultrasonic sensing solutions for flow, level, proximity, position, imaging and distance measurement
Ultrasonic sound waves are vibrations at a frequency above the range of human hearing (>20 kHz) that can travel through a variety of mediums (air or fluid). These techniques, like time of flight or Doppler, are used to measure flow, detect objects, perform concentration analysis and measure distances without making physical contact. Ultrasonic sensors can be used to detect a wide variety of materials regardless of shape, transparency or color.
