Flow meters help Smart Cities measure the volume of natural gas or water at a specific time or over a long period. The measurement is then displayed on low-power segment LCDs, often driven by segment LCD drivers on a MCU.
Advanced flow meters incorporate RF communication interfaces for connecting to one-way or two-way RF meter reading systems.
