Smart-home sensor solutions - Bringing an antiquated metering system into the IoT universe

Creating a smart energy meter requires more than just a low-power, long-range, wireless module. The mechanical methods of measurement used by many meters are similar to those first installed with utility grids in the late 19th century, with an analogue output that is unable to communicate with a digital wireless solution.

One of our customers sought to overcome this challenge with a new digital meter. The design had to be cost-effective, robust, absolutely reliable, and able to operate for many decades. It also had to be ultra-low power, with only one small battery for a power source. The customer established they could use ultrasonic technology to measure the flow of water in the pipe; however, they found that even minor fluctuations in temperature caused water density (and therefore volume) to change. To address this, they needed a solution that could accurately measure the water temperature and instantly respond to minor changes.

Finding the perfect solution from a vast portfolio of technologies

We identified Shibaura thermistors as the perfect solution. Offering instant, accurate temperature measurement, their incredibly robust design provides a zero failure rate with an operating life of more than 30 years. The quality of the solution gave the customer total assurance with best-in-class performance.

This resulted in the creation of a new digital water meter that was both cheaper and more accurate than its mechanical predecessor. With no submerged mechanical parts, reliability was also improved. Most importantly, the solution enabled the customer to realise their ultimate ambition of a connected meter, which is now being deployed across Europe.
