What Allmess does

Allmess GmbH, founded in 1978 and headquartered in Oldenburg in Holstein, Germany, manufactures water meters, heat/cooling meters, and remote reading systems for the German residential, commercial, and industrial markets. The company is a pioneer in ultrasonic measurement technology for thermal energy, producing wear-free compact and split heat meters (e.g., Integral-MK UltraMaXX, CF Echo II, Megacontrol CF 51), residential capsule water meters (Messkapsel-System MK +m, System-V +m) with millions of installed units, large Woltmann and single-jet water meters for industrial applications, and proprietary EquaScan wireless and M-Bus wired remote reading infrastructure. All products are conformity-assessed under the EU MID and the German Eichgesetz, with a statutory 6-year calibration cycle managed via on-site state-approved testing facilities. Allmess is a wholly-owned subsidiary of US-listed Itron Inc. (NYSE: ITRN) and operates as Itron's German center of excellence for water and heat metering.

The company operates a three-tier B2B distribution model: Allmess supplies products to sanitary and heating wholesale trade (Fachgroßhandel), which in turn sells to qualified plumbing and heating installers (Fachhandwerk) who perform installation in buildings. Revenue is generated primarily through one-time hardware sales of meters and reading systems, supplemented by a recurring MietService rental model under which property owners contract directly with Allmess for meter rental aligned to the 6-year calibration cycle, with installation routed through the wholesale channel. Pricing is not publicly disclosed but is published as 2026 price lists including conformity fees. The company holds ISO 9001 and ISO 14001 certifications, employs approximately 200 people, and is actively positioning its portfolio for the EU Energy Efficiency Directive (EED) requirement for remote-readable meters by December 31, 2026. Strategic partnerships include a Systempartnerschaft with Eisenwerk Wittigsthal GmbH for mounting-system compatibility and a strategic technology relationship with parent Itron for R&D, OMS-standard compliance, and global platform access.

Revenue model

1. Water Meter Sales: Allmess manufactures and sells a comprehensive range of water meters including residential water meters (System-MK +m, System-V +m), house water meters (multi-jet, piston type), and large water meters (Woltmann, single-jet). Products are sold through the three-tier distribution channel (wholesale → tradespeople). Water meters are subject to statutory calibration requirements with a 6-year validity period requiring periodic replacement.
2. Heat and Cooling Meter Sales: Allmess sells heat meters (ultrasonic compact heat meters, split heat meters) and cooling meters. Products use ultrasonic technology for high accuracy and longevity. Distribution is through the same three-tier wholesale and tradespeople channel.
3. Rental Service (MietService): Allmess offers a complete rental service for water meters, heat meters, and remote reading system components. Property owners sign rental contracts directly with Allmess; installation is handled by tradespeople via wholesale. The rental model aligns costs with the statutory 6-year calibration cycle and allows costs to be passed through heating and water cost allocations to tenants. A digital app-based rental management platform is also available.
4. Remote Reading Systems (EquaScan, M-Bus): Allmess sells remote reading systems including the EquaScan wireless system (with Walk-by and FNet variants), M-Bus wired system, and pulse modules for remote display. These systems enable automated consumption data collection, meeting EED (Energy Efficiency Directive) requirements for mandatory remote reading by end of 2026.

Partnerships

Two partnerships are on record, tiered core.

• Eisenwerk Wittigsthal GmbHcoreStrategic or Co-development PartnerAllmess and Wittigsthal have established a strategic system partnership (Systempartnerschaft) to jointly develop innovative mounting solutions for water and heat meters. The partnership ensures ideal compatibility between Allmess measuring devices and Wittigsthal mounting modules (Einrohranschlussteile, EATs), allowing the Allmess Integral-MK UltraMaXX heat meter to be compatible with all existing Wittigsthal EATs. Both companies work closely together to optimize the three-tier distribution channel, ensuring Fachhandwerk can perform calibration exchanges and Fachgroßhandel supplies the material. Both companies use identical sales representations in all territories.
• Itron Inc.coreOthersAllmess GmbH is a wholly owned subsidiary of Itron Inc., an internationally active company offering the complete meter program with associated systems and services for the consumption measurement of electricity, gas, heat, and water globally. Allmess serves as Itron's German center of excellence for water and heat meters. Itron provides Allmess with R&D resources, global reach, and access to technologies such as the EquaScan wireless system and the Open Metering System (OMS) standard. Allmess products are branded as Itron on some platforms, and the customer portal links to customer.itron.com.
