Ultrasonic sensing subsystem reference design for gas flow measurement

Description

This reference design helps designers develop an ultrasonic gas-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 64KB MSP430FR6043 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: +/-250ps zero flow drift (ZFD) and 500ps single-shot standard deviation (STD)Low power consumption: ±1% flow accuracy up to 12:000 lph with dynamic range of 200:1Three lph minimum detectable flow rateRobust performance against variation of transducer characteristics over temperature
Applications
  • Gas meter
  • HVAC fluid leak detector
