This video provides a demonstration of the test set-up using the MSP430FR6047 microcontroller(MCU) to accurately measure water flow using ultrasonic sensing technology. The MSP430FR6047 MCU has an integrated analog-front-end (AFE) for ultrasonic sensing that provides highly accurate and precise measurement to detect low flow rates. The demonstration includes the EVM430-FR6047 evaluation module and Ultrasonic Design Center for software libraries and a GUI.
