Key Document


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.

  • Ultra low power ~ 20 years lifetime with battery
  • ADC based approach, meets ISO 4064-1 EEC applicable norms
  • Robust to signal amplitude variations – insensitive to received signal amplitude
  • Allows low power implementation with optimized signal processing
  • Supports Sub-1GHz and 2.4GHz RF wireless communication modules
  • Integrated low-power segment LCD controller
