Contazara

What Contazara does

Contazara (legal name: Contadores de Agua de Zaragoza S.A.) is a privately-held Spanish industrial company founded in 1984 and headquartered at La Cartuja Baja, Zaragoza. It designs, develops, produces, verifies, and provides after-sales service for electronic water meters and remote-reading (telelectura) equipment used by public, mixed, and private water-management utilities. The company was the first organisation in the world to develop and commercialise a digital (smart) water meter and is documented as the pioneer in NB-IoT smart water meter commercialisation.

The product portfolio spans three hardware technology families: the CZ4000 (volumetric), CZ3000 and CZFIGHTER (velocity), and CZUS (ultrasonic, no moving parts, R500-certified). Each family is offered in connectivity variants including NB-IoT, integrated 868 MHz radio, and 169 MHz radio under the WIZE Alliance standard. The CZCloud software platform — comprising Cloud de lecturas (high-availability reading storage with web services and FTP), CZView (historical visualisation), and CZNetwork (NB device management) — adds a SaaS layer atop the hardware. Complementary offerings include the SMART NB IoT communication device for meter banks, turnkey "Llaves en Mano" municipality transformation services, and ENAC-accredited calibration and testing laboratory services.

Commercially, Contazara operates a direct B2B field-sales motion selling to utilities in Spain, France, Portugal, Poland, Colombia, Chile, Peru, Ecuador, North Africa, and the Middle East. Revenue mechanics combine hardware sales, professional services for turnkey installations, metrology laboratory services, and recurring software subscriptions through CZCloud. The company holds a deep certification stack (ISO 9001, 14001, 45001, 27001, 14006, 9004, UNE 0060, ENS High, EU MID Modules H1 and D) and has accumulated more than two decades of quality and innovation awards, including Spain's Premio Nacional Industria Conectada 4.0 (2020) and the Príncipe Felipe Award for Business Excellence (2007).
