Ultrasonic Sensing for More Accurate and Precise Water Flow Meters

Overview of the MSP430FR6047 MCU-based ultrasonic sensing to get you started evaluating and designing with the MCU and related hardware and software.

Ultrasonic sensing techniques have been popular in smart water meters because the technology avoids any moving parts which are prone to degrade over the lifetime of the product. The MSP430FR6047 microcontroller (MCU) family takes ultrasonic sensing solutions to next level of performance delivering <25ps of accuracy, detection of low flow rates <1 liter/hour and high precision of <5ps. TI's MSP430FR6047 ultrasonic sensing MCUs have a unique integrated analog-front-end (AFE) that lets developers add more intelligence to flow meters by taking advantage of a complete waveform capture feature and analog-to-digital converter (ADC)-based signal processing. In addition, the integrated MSP430FR6047 devices reduce water meter system component count by 50 percent and power consumption by 25 percent, enabling a meter to operate without  having to change the battery for 10 or more years. 

This training series provides an overview of the MSP430FR6047 MCU-based ultrasonic sensing offering to help developers get started evaluating and designing with the MCU and related hardware and software including the EVM430-FR6047 evaluation module and the MSP430 Ultrasonic Design Center with GUIs and tools to get your design started.
