What Axioma Metering does

Axioma Metering (legal entity UAB Axioma Metering) is a Lithuanian privately-held manufacturer and technology supplier of smart ultrasonic metering devices for water, heat, and cooling, headquartered in Kaunas with an administrative office in Vilnius and operating in over 80 countries. Founded in 1992 as the first company in Lithuania to create an ultrasonic heat meter, the company holds multiple patents on ultrasonic measurement technology and today offers a product portfolio organized under the QALCOSONIC brand, including the W1 family of smart ultrasonic water meters (with regional variants for Europe, USA, and industrial diameters), the F1 IP68 water meter for larger nominal diameters, and the E3/E4 ultrasonic heat and cooling (BTU) meters. Devices use static (no moving parts) ultrasonic measurement with up to 16-year battery life and IP68 protection, and support multiple communication protocols including LoRaWAN, NB-IoT, wM-Bus, M-Bus, ModBus, BACnet, and NFC. The portfolio also includes an external antenna accessory for challenging installations and a meter verification/calibration service for both Axioma and third-party meters.

The commercial model is B2B enterprise hardware sales to water utilities, district heating operators, municipalities, and metering service operators under multi-year contracts and tenders, supplemented by channel partners in specific geographies (notably IDEA in Italy and Heitland in Germany). Revenue is generated primarily through one-time hardware purchases with custom quotation-based pricing and no disclosed per-unit pricing. Two complementary software platforms extend the offering: AxiReach, a cloud-based remote device management platform built on Thingsboard and deployed on Microsoft Azure (EU region) that supports monitoring, diagnostics, COTA, and FUOTA commands, and AxiLink, a professional mobile application used by authorized field technicians to interact with meters locally via NFC or optical port. Meter verification, calibration, and repair services are provided through a factory laboratory in Kaunas and partner institutes.

Headcount has grown to approximately 500 employees as of 2026, and the company has supplied over 3 million meters globally with reported 40% revenue growth in 2025. Notable reference customers include Italy's Aquedotto Pugliese (1M+ meters across 19 tenders via IDEA), Germany's Heitland (500,000+ meters across 250 utilities), Oman National Energy Center (260,000+ meters), Tashkent Utilities in Uzbekistan (700,000+ planned), and Lithuania's Vilniaus vandenys (250,000+ NB-IoT meters in Vilnius). The company holds ISO 9001/14001/45001/27001 certifications and EU MID, WRAS, ACS, ICIM, KIWA, OIML, NSF/ANSI/CAN 61, NTEP, and FCC certifications, and is co-funded by EU/ERDF programs for ongoing R&D and renewable energy investments.

Core offering

Axioma Metering manufactures ultrasonic smart water meters (QALCOSONIC W1 and F1 series) and ultrasonic heat/cooling meters (QALCOSONIC E3 and E4) for utilities, municipalities, and metering service operators. The devices use static (no-moving-parts) ultrasonic measurement supporting LoRaWAN, NB-IoT, wM-Bus, M-Bus, ModBus, BACnet, and NFC communications, with up to 16-year battery life and IP68 protection. The hardware is complemented by the AxiLink professional mobile application for field technicians, the AxiReach cloud-based remote management platform (built on Thingsboard and Microsoft Azure EU), and a meter verification and calibration service offered through the company's factory laboratory in Kaunas.

Product overview

Axioma Metering is a Lithuania-founded smart metering manufacturer and technology supplier offering a portfolio of connected metering devices and supporting software platforms. The product portfolio centers on two core device families: (1) smart ultrasonic water meters — the QALCOSONIC W1 series (available in A design, B design, B design Brass, DN25–DN50, and USA variants) and the QALCOSONIC F1 IP68 — and (2) smart ultrasonic heat and cooling meters — the QALCOSONIC E3 and E4 (new-generation BTU meters). These devices use static ultrasonic measurement technology (no moving parts) for high long-term accuracy and support multiple communication protocols including LoRaWAN, NB-IoT, wM-Bus, M-Bus, MODBus, BACnet, and NFC. The device portfolio is complemented by the External Antenna accessory for connectivity in challenging installations. Axioma Metering's software ecosystem includes AxiLink (a professional field mobile application for on-site meter interaction via NFC/optical port) and AxiReach (a Thingsboard-based cloud platform deployed on Microsoft Azure for remote device monitoring, diagnostics, and OTA firmware/configuration management). The company also provides Meter Verification Services — factory and on-site calibration, testing, and repair for smart and mechanical meters from Axioma Metering and other manufacturers. This integrated hardware-plus-software-plus-services approach addresses utility, municipality, and commercial metering operators across Europe and globally.
