What is Axioma Metering?

Founded in Lithuania, Axioma Metering has a long-standing reputation for innovation in the metering industry. The company introduced its first ultrasonic heat meter in 1992 and has continued to build on that foundation with a growing range of advanced ultrasonic heat and water meters.

In 2019, Axioma opened one of the most advanced metering production facilities in the Baltic States – consolidating its manufacturing under one roof to ensure high quality, efficiency, and technological precision. Unlike many manufacturers, Axioma doesn’t just assemble hardware; it develops its own metering technologies in-house.

One of its flagship products today is the Qalcosonic W1 Ultrasonic Smart Water Meter. Designed and produced entirely by Axioma, the W1 provides accurate measurement of both cold and hot water in residential buildings, multifamily units, and small commercial premises. With no moving parts, the W1 leverages advanced ultrasonic technology for long-term stability, durability, and precise readings – making it a reliable and cost-effective choice for modern water metering needs.

Axioma Metering collaborates with utilities, businesses, and municipalities worldwide to modernize infrastructure and deliver accurate, real-time consumption data through its suite of high-performance metering solutions.

Below are just a few examples of how Axioma’s ultrasonic meters are helping cities and utilities modernize water infrastructure, improve efficiency, and reduce losses.

Tashkent, Uzbekistan

Challenge:
Tashkent launched a major modernization effort in 2022 to address aging infrastructure and inefficiencies in its heating and water networks, where up to 40% of heat was being lost and revenue collection was hampered by manual billing.

Axioma’s Role:

• Supplied tens of thousands of Qalcosonic W1 smart meters, with a roadmap to over 700,000 installations
• Enabled automated meter reading to eliminate billing delays and manual data entry
• Helped reduce inefficiencies and protect utility revenue

IDEA, Italy

Challenge:
Italy faces one of the highest water loss rates in Europe, with 42% of water unaccounted for. Many networks are over 30 years old and require modernization.

Axioma’s Role:

• Delivered more than 1 million smart meters for Italy’s largest IoT water metering project
• Enabled real-time leak detection and cut water losses by up to 30%
• Helped reduce operational costs through automation and long-life meter performance

Heitland, Germany

Challenge:
New regulations in Germany require real-time consumption data. Utilities also face cost pressure due to short 6-year replacement cycles and the inefficiencies of manual reads.

Axioma’s Role:

• Supplied over 500,000 meters for a national rollout now adopted by 250+ utilities
• Enabled 12+ year replacement cycles with durable, low-maintenance ultrasonic meters
• Helped utilities increase billed water volumes by 5% through more accurate measurement

Oman National Energy Center, Oman
