Description

The TIDM-ULTRASONIC-FLOW-TDC is a reference design for an ultrasonic flow meter (water, gas or heat meter) with LCD built using a Time-to-Digital converter and an ultra-low power MCU. Solution includes optimized leakage detection, low power consumption, and a small form factor that are important requirements for water, heat and gas meter applications. This design also includes a high efficiency DC-DC converter for system power.

Features
  • A small form factor, ultra-low power design
  • Ultrasonic Time of Flight measurement - No moving parts
  • Highly efficient DC-DC converter for system power
  • Super-cap design for power supply of RF module
  • Platform Design with sockets for RF, power module and MCU I/Os
  • PC GUI and firmware ready
