Description

The TIDM-1002 reference design helps designers develop an ultrasonic gas metering sub-system using a unique proprietary algorithm and an analog-to-digital converter (ADC) based sampling technique. The TIDM-1002 is based on a 256-KB MSP430™ microcontroller (MCU), the MSP430FR5994, with integrated low energy accelerator (LEA) for digital signal processing and discrete analog front end (AFE) chipsets, which provide superior metrology performance with low-power consumption.

Features
  • Best-in-class metrology performance: <1ns zero flow drift and <2ns single shot standard deviation
  • Low-power consumption: <50µA with 400kHz transducer and 1 sample per second
  • Flexibility to test different meters and transducers
  • Easy to test and customize using a PC graphical user interface 
  • Compatible with LaunchPad™ development kit ecosystem
