How is radar technology utilized to measure flow?
A non-contact sensor transmits a radar beam that interacts with the fluid and reflects back signals at a different frequency than transmitted. These reflected signals are compared with the transmitted frequency. The resulting frequency shift provides an accurate measure of the velocity and the direction of the flow. Level is detected by ultrasonic pulse echo. Flow is then calculated based on the Continuity Equation Q = V x A, where Q = flow, V = average velocity and A = area.
