Sonar flow technology is a new class of industrial flow meters, utilizing measurement principles that are distinct from all conventional flow meter technologies. CiDRA’s SONARtrac flow meters utilize patented sonar-based array processing techniques to “listen” to, and interpret pressure fields generated by turbulent pipe flows. The SONARtrac family of flow meters provides accurate and reliable non-contact and robust flow measurement for a wide range of single phase and multiphase flows. SONARtrac flow meters are available in “clamp-on” configurations that install on existing process lines, eliminating the process disruptions associated with installing other types of flow meters.
