Get accurate results without physical contact!
CiDRA’s SONARtrac Volumetric Flow and Entrained Air Measurement System is a breakthrough in process measurement technology. The SONARtrac clamp-on, non-contact system allows for on-line real-time measurement of the volumetric flow in difficult to measure slurries and fluids; and the amount of entrained air present in any liquid-continuous-phase process flow. The system also provides a measurement of only the liquid portion of the flow by compensating for the amount of entrained air in the process line. SONARtrac measurement systems do not utilize ultrasonics; they employ patented sonar array processing techniques to listen to, and interpret, flow turbulence and sound fields generated by the machinery, piping and process flow. This passive listening approach results in measurement of the flow rate and amount of entrained air with a high degree of accuracy and repeatability.

Industries Served How It Works
Passive Sonar Technology – CiDRA’s SONARtrac technology represents an innovative new class of industrial measurement instrumentation. This sonar technology utilizes array processing techniques similar to those used in the field of sonar processing.
The SONARtrac Volumetric Flow and Entrained Air Measurement System utilizes an array of sensors that are wrapped around the pipe. The flow rate and percent of entrained air by volume is determined using CIDRA’s array processing techniques and are available as meter outputs.
Liquid and Slurry flow rate is measured by analyzing the flow turbulence in the process stream, while the sound field is used to determine the sound speed, or velocity at which sound propagates, through the process medium. The entrained air percentage is then calculated directly from the measured sound speed.
