Sontex Deutschland GmbH

What Sontex Deutschland GmbH does

Sontex Deutschland GmbH is the German sales and customer-support subsidiary of Swiss metering specialist Sontex SA, established in 2011 to serve German-speaking markets. The German entity is a lean 12-person operation focused on partner enablement and customer support rather than direct manufacturing, with production, R&D and the ISO/IEC 17025 accredited calibration laboratory (operating since 1996) housed at the parent's 4,000 m² site in Sonceboz, Switzerland. Sontex SA itself was created in 1989 via a management buy-out of the heat-meters division of Sonceboz S.A., giving the group more than three decades of heritage in sub-metering.

The product portfolio is built around proprietary fluidic-oscillation measurement technology and spans four families: thermal energy meters (Supercal 5 series, Superstatic series including the 789 and 739), electronic heat cost allocators (Sontex 565, 566, 868 and the 878 LoRaWAN variant), ultrasonic water meters (Superaqua 1, 3, 3 Composite and 5), and an IoT communication layer comprising Supercom radio modules (W2-L, P) and the Superlink C gateway. Software platforms Sonexa and Tools Supercom provide metering-data management, while multi-protocol support (LoRaWAN, wM-Bus, OMS, M-Bus, BACnet, Modbus) allows integration into energy-utility AMI, building-automation and home-automation stacks. The portfolio is MID-compliant for billing-grade deployment across European regulated heating-cost and water markets.

Revenue is generated predominantly through quote-based B2B hardware sales distributed via an authorized partner network covering 30+ countries, with ancillary recurring revenue from the Sonexa and Tools Supercom software platforms. End customers include energy utilities, property managers, building-automation integrators and developers of residential, commercial and institutional real estate (large developments, hospitals, corporate campuses). The model is anchored by long MID-regulated replacement cycles, low churn from installed-base refresh, and the channel's structural diversification across multiple country partners and customer segments.

Core offering

Sontex Deutschland GmbH, as the German arm of Sontex SA, sells and supports a portfolio of metering systems for thermal energy, water consumption, and heat cost allocation. Core offerings are thermal energy meters (Supercal 5 series, Superstatic 789/749, Supercal 739), ultrasonic water meters (Superaqua 1/3/5), electronic heat cost allocators (Sontex 565/566/868/878), Supercom radio communication modules, the Superlink C data gateway, the Sonexa cloud data platform, and the Tools Supercom readout software, sold exclusively through authorized regional distribution partners.

Product overview

Sontex offers a comprehensive portfolio of innovative metering systems for energy and water consumption measurement. The core product lines include thermal energy meters (Supercal 5 series, Superstatic series, Supercal 739), heat cost allocators (Sontex 565, 566, 868, 878), and ultrasonic water meters (Superaqua series). These are complemented by radio communication modules (Supercom series) enabling wireless data readout via Sontex Radio, wM-Bus/OMS, LoRaWAN, M-Bus, BACnet, and Modbus protocols. The ecosystem is unified by the Sonexa data platform for cloud-based consumption data management, Tools Supercom software for walk-by readout operations, and Superlink C gateway for automated data collection. The portfolio serves three main application areas: home automation (for fair cost allocation in residential buildings), building automation (for energy optimization), and energy suppliers (for district heating networks and utility applications).
