Engelmann Sensor

What Engelmann Sensor does

Engelmann Sensor GmbH is a Wiesloch-Baiertal, Germany-based manufacturer of electronic submetering devices, founded in 1976/1977. The company designs, produces, and distributes heat meters (under the SensoStar family, available in mechanical impeller-based and ultrasonic variants), cooling meters (Kältezähler), water meters (WaterStar M, FlowStar U), heating cost allocators (Unifix, HCA e2), smoke detectors, and the underlying communication infrastructure — wireless M-Bus radio modules, LoRaWAN modules, the Gateway data collector, and a fourth-generation Read-out Software with OMS-compliant protocol support. Manufacturing is conducted at a second site in Hirschhorn am Neckar, and Engelmann holds MID and PTB certifications required for regulated EU submetering deployments.

The company sells primarily through a hybrid direct-and-channel model. In the DACH region, regional sales managers and a customer support team serve property managers, heating cost service providers (Heizkostenabrechner), utilities, and district heating operators. International markets — spanning Italy, Spain, Portugal, the UK, Ireland, Switzerland, Hungary, Poland, Croatia, Slovenia, Turkey, the UAE, India, Southeast Asia, and Australia — are covered by a layer of international sales directors supplemented by country-specific authorized distributors. Revenue is generated predominantly through hardware sales, complemented by software licenses (one-time), training and certification services priced at €450 per participant per day, and sustainability offerings such as the SensoStar 3 Recycling program.

Since February 2026, Engelmann has operated under majority ownership of Rivean Capital, which acquired the stake from DPE Deutsche Private Equity. Leadership comprises Managing Directors Michael Keuthen and Dietrich Fabricius. The company employs 101–250 people, maintains multi-language marketing in German, English, French, Spanish, Italian, and Chinese, and participates in industry events such as WETEX, IWA World Water Congress, and Enlit Europe. Over its nearly five-decade history, Engelmann has produced more than 10 million meters.
