Industrial process control frequently requires the accurate measurement of fluid flow. There are several widely applied methods for measuring flow, each having particular advantages which may apply to a specific application.

Ultrasonic flow meters measure flow indirectly by calculating transit time of a sound wave through, or reflecting from, a flowing fluid. The velocity of the fluid has an impact on the transit time, from which a flow rate can be calculated. Attributes of ultrasonic flow measurement that may determine suitability for a particular application include:

  • Transducers can be clamped on exterior pipe surface where measurement is needed.
  • Non intrusive measurement technology prevents contact between media and measuring elements.
  • No significant pressure drop associated with measuring device installation.
  • Reduced leak potential.
  • No moving parts.
  • Comparatively higher cost than some other technologies.
  • Fluid characteristics must be well known for proper application.
  • Pipe cross section must be completely filled by media to acquire accurate flow measurement.
