Ernst Heitland GmbH & Co. KG
About
Ernst Heitland GmbH and Co. KG, founded in 1921 in Solingen, Germany, is a manufacturer and independent distribution partner for water, gas, and heat metering technology with over a century of operational history. Having shipped more than 10 million meters and currently producing over 650,000 units annually with approximately 80 employees, Heitland is preparing for fifth-generation family leadership under deputy managing director Jan Bangert and next-generation family members Lisa and Julian Humbs. The company's ultrasonic water meter portfolio includes the QALCOSONIC W1 for residential and bulk applications, the QALCOSONIC F1 for large-diameter commercial metering, and the RubinSonic for high-volume water distribution. Apartment sub-metering options comprise Modularis capsule and surface-mount meters (dry-running, IP64, MID class up to R80h/R40v) and WeCount-S meters (IP68, with LoRaWAN, OMS, NFC, leak and burst detection, and up to 16-year battery life reaching R500h/R315v). Domestic water meters span Q3=2.5 to Q3=16 in ring piston, single-jet, multi-jet, and ultrasonic variants. On the gas side, Heitland distributes diaphragm gas meters (G2.5 to G100), rotary piston gas meters for high-accuracy applications, turbine gas meters (G65-G6500), and gas pressure regulators for household connections. Heat metering uses Qalcosonic E3 and E4 ultrasonic technology for thermal energy measurement. Smart metering connectivity spans NB-IoT, wMBus OMS, LoRaWAN, and wired protocols (MBus, ModBus, BacNet). The proprietary SURU Connect NB-IoT platform enables remote meter reading with no recurring connectivity fees, while a partnership with AXIOMA (Lithuania) extends smart metering capabilities. Heitland operates four accredited testing stations (WNW51, GNW51, WH51, GH51) providing EU Measuring Instruments Directive conformity assessment, periodic calibration, gas meter reconditioning, court-admissible meter reading documentation, and water analysis services, all under ISO 9001 and ISO 14001 certification.
