New intelligent ADDRA water meter with integrated valve — a compact solution for challenging installation conditions.

What to do if the site is perfect for installing a smart water meter but… there is physically no space for an external valve? We faced this challenge in practice and turned it into a breakthrough.
ADD GRUP, an international developer of smart water and energy metering solutions, introduced an innovation based on real implementation experience. As part of a major project in Greece, several thousand ultrasonic ADDRA meters with remotely controlled valves were installed. Customers highly appreciated the capabilities of remote water shut-off, precise monitoring, leak protection, and integration with smart platforms.However, the project gave not only positive results but also important feedback. Installation teams reported a key obstacle: in some sites, installing a meter with an external valve was impossible or difficult due to lack of space. This is especially relevant in old buildings, compact utility niches, and areas with limited access. In some cases, installation required actual destruction of the existing water infrastructure.For many potential clients in other countries, this became a reason to refuse valves, although they are a very necessary solution to combat overconsumption, especially in drought conditions.
ADD GRUP responded to market demand and presented a new version of the ADDRA smart meter with an integrated valve, whose design does not increase pipe length. Now the device is easily installed within the same dimensions as a regular water meter:

• DN15 – length 110 mm
• DN20 – length 130 mm (in development)
•  DN25 – length 195 mm (in development)

This solution removes one of the toughest barriers to the widespread implementation of smart water metering technology with supply management capability. For the first time on the market, a compact ultrasonic meter with remote water supply control can be integrated without changes to existing engineering networks.In addition to compactness, ADDRA offers optional replaceable external Power Bank providing up to 30 years of autonomous operation, including daily valve activation mode.

This is critically important for sites with intensive water management such as:

• Apartment buildings with remote shut-off for non-payment,
• Hotels with prepaid water consumption models,
• Rental and communal properties where resource consumption control is crucial.

Reliability and long service life make ADDRA a suitable choice for large infrastructure projects, public housing modernization programs, and ESG-oriented developers.

Why ADDRA?

• Easy installation — fits like a regular water meter without pipeline modifications
• Smart City ready — supports NB-IoT, LoRa, WM-Bus
• Ultrasonic accuracy — stable operation without mechanical wear
• Intelligent features — protection against leaks, backflow, tampering, and dry housing
• Flexible management — supports prepayment, remote shut-off, and mobile payments
• Minimal maintenance — no regular calibration needed

The smart water metering market is developing rapidly, but only solutions adapted to real site conditions find true application. The new ADDRA with integrated valve is exactly such a solution: compact, reliable, smart, and focused on installation convenience without compromising functionality.We know what you need — a modern solution for remote water supply management easily integrated into any infrastructure — ADDRA from ADD GRUP offers just that.
