Water meters, like most systems, are seeing advancements in measurement and precision. One key driver for this change is the metrology methodology transitioning from mechanical-based to electronic sensors, such as Hall sensors or ultrasound. Another introduction is automatic meter reading (AMR) technology, integrating into LoRa, Bluetooth® Low Energy (LE), NB-IoT, and other communication standards.
Renesas has developed a solution based on a tunnel magnetoresistance (TMR) sensor, which enables lower power consumption and extends battery life to 5-7 years (as required in the market).
