Aquiba, a joint venture between Sentec and Takahata Precision, has selected Energy Micro's EFM32 Gecko microcontroller for use in its A200 smart water meter.
The EFM32G890F128 microcontroller handles the A200's high accuracy flow measurement, data logging, secure communication and application firmware upgrades.
The Aquiba A200 smart water meter has no moving parts and provides good measurement accuracy even at the lowest flow rates and over the product's full service lifespan. To allow water operators to plan for future changes in climate and network infrastructure, the A200 also has the in-built flexibility to enable it to be rapidly adapted to meet future metering requirements.
Mark England, CEO of Sentec said, in designing the A200, “We needed to move to a microcontroller that could give us the 32-bit data processing but at a power consumption that would deliver a battery life of 15 years. What's more, it needed to be able to support our unique operating system and modular software and handle over-the-air field upgrades as well.”
