This reference design, featuring the CC1312R7 and MSPM0L2117 MCUs, is a fully functional battery powered rotary smart water meter. The instantaneous and total flow is updated on the always on LCD display and sent out in a C-mode telegram over OMSv4.2.x wM-Bus protocol; while the rotary sensing and magnetic tampering detection are also implemented and optimized for minimal power consumption.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
