TIDM-ULTRASONIC-FLOW-TDC
Ultrasonic Water Flow Meter Design using Time to Digital Conversion
TIDM-ULTRASONIC-FLOW-TDC
Overview
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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
