SONARtrac Measurement Technology - How It Works
SONARtrac® Measurement Technology - How It Works
CiDRA’s patented sonar technology utilizes array processing techniques to measure volumetric flow and entrained air.
The SONARtrac system measures volumetric flow rate by combining phase and frequency components of the turbulent eddies as they convect past the array of sensors.
In order to determine the amount of entrained air present, the SONARtrac system measures the speed at which acoustic waves pass through the sensor array. The measured sound speed is then correlated to the phase fraction of the two component mixture.
