Ultrasonic Sensing Water Meter Front-End Reference Design

Description

This reference design helps designers develop an ultrasonic water-metering subsystem using an integrated: ultrasonic sensing solution (USS) module: which provides superior metrology performance with low-power consumption and maximum integration. The design is based on the 256KB MSP430FR6047 microcontroller (MCU): with integrated high-speed: ADC-based: signal acquisition and an integrated low energy accelerator (LEA) to optimize digital signal processing.

Features
  • Best-in-class metrology performance: 25-ps zero-flow drift (ZFD) and 32-ps single-shot standard deviationLow-power consumption: Approximately 2.5 μA with 1-MHz transducer at 1 measurement per second for metrologyFlexibility to test different pipes and transducers; direct interface to pair of transducersEasy to test and customize using Ultrasonic Sensing Design Center graphical user interface (GUI)Ultrasonic sensing software library includes time of flight (ToF) algorithmsStandalone demo using liquid-crystal display (LCD)
