TIDM-ULTRASONIC-WATER-FLOW-MEASUREMENT Reference Design

Texas Instruments

Ultrasonic Water Flow Measurement Reference Design

Description

This Ultrasonic Water Flow Measurement system is ideal for providing highly accurate measurement across wide flow ranges as low as 1.4gpm. The design is based on a single MCU with discrete analog components. It uses a unique propriety algorithm that improves robustness and performance in flow measurement across wide range of operating conditions. This design is fully compatible with TI RF plug-in evaluation modules for wireless AMI networks.

Features
  • Ultra low power ~ 20 years lifetime with batteryADC based approach: meets ISO 4064-1 EEC applicable normsRobust to signal amplitude variations – insensitive to received signal amplitudeAllows low power implementation with optimized signal processingSupports Sub-1GHz and 2.4GHz RF wireless communication modulesIntegrated low-power segment LCD controller
Applications
  • Flow transmitter
Product Categories
  • MSP430 microcontrollers
