ADD GRUP presents a new ultrasonic water meter with MultiRAT support — a universal solution that ensures stable wireless connectivity in any coverage area and radically simplifies the implementation of smart water metering. This device was created in response to one of the main challenges in remote monitoring: unstable and unpredictable wireless signal availability across regions or even within a single neighborhood. Today, relying on just one technology is not feasible — neither NB-IoT, LoRaWAN, nor Wireless M-Bus can provide 100% coverage. Signal can “disappear” due to dense buildings, shielding materials, natural barriers, or network congestion. In practice, this means utilities must purchase and install different meter models for each technology, increasing ownership costs and complicating logistics, maintenance, and support.
The next-generation meter addresses this problem by using MultiRAT — a system that enables one device to simultaneously support three communication channels: NB-IoT, LoRaWAN, and Wireless M-Bus. The meter automatically determines which technology offers the best signal and data transmission stability at the moment and switches to it without user intervention. This not only simplifies installation but makes the entire project more reliable and resilient. By implementing such a solution, operators get a single type of equipment suitable for all coverage areas and can confidently plan expansion without the risk of communication failures.
The new meter is not just a universal communication device, but also a high-precision measuring instrument. It is based on time-tested ultrasonic technology with no moving parts and maintains high accuracy throughout its entire lifespan. The device is designed for diverse conditions — from urban networks to remote areas, from apartment buildings to commercial facilities and distributed infrastructure systems. Its housing is resistant to moisture, dust, and mechanical impact, while built-in diagnostic algorithms can detect abnormal situations in real time: leaks, dry run, tampering attempts, magnet use, reverse flow, and low battery. All events are logged and transmitted to the management system, providing full operational transparency.
The meter is available in two versions — with and without a shut-off valve. The valve version allows for remote water shutoff or flow limitation, enabling scenarios like prepayment, consumption limits, or emergency cutoffs. This provides an additional level of control and enables utilities to respond quickly to debts, leaks, or violations. The non-valve version is used where precise measurement and reliable data transmission are needed — for example, in residential buildings or network upgrades.
The device fully integrates with ADD GRUP’s communication and server ecosystem, including Head-End Software, cloud interfaces, visualization and analytics tools, and apps for operators and users. Data transmission uses standard protocols, ensuring compatibility with existing billing, CRM, and SCADA systems. Flexibility in choosing the system architecture — from centralized to decentralized — allows adaptation to any customer need, from small municipalities to national water operators.
Thus, the new MultiRAT water meter is a comprehensive solution combining measurement accuracy, smart management, and full independence from coverage conditions. It reduces deployment risks, cuts down on field visits, minimizes emergencies, and simplifies commissioning. It is a step forward in developing digital water supply systems that makes smart metering more accessible, reliable, and economically viable.
