TIDA-01228 Reference Design

Texas Instruments

Low-Power Water Flow Measurement With Inductive Sensing Reference Design

Description

This reference design demonstrates a highly-integrated solution for this application using an inductive sensing technique enabled by the CC1350 SimpleLink Wireless MCU and FemtoFET MOSFET. This reference design also provides the platform for integration of wireless communications such as wireless M-Bus, Sigfox, or a proprietary protocol. Water utility providers who wish to add Automatic Meter Reading (AMR) capability face the choice of replacing all of their existing meters or installing a simple electronic add-on module, which will accurately measure the water flow rate and wirelessly transmit the results. Such add-on modules can provide the least expensive solution to provide AMR features to consumers.

Features
