KonvexGV

What KonvexGV does

KonvexGV (legal entity: KONVEX gasna i vodo tehnika d.o.o.) is a Serbia-based, privately held limited liability company founded in 1994 and headquartered in Zemun (Belgrade area). The company operates as a specialized distributor and service provider for gas and water measurement equipment, holding exclusive representation of Elster GmbH products in Serbia and additional partnerships with AIUT, Schuetz Messtechnik, Honeywell, ESKA Valve, and Wigersma & Sikkema. Its customer base is concentrated among Serbia's largest natural gas distribution utilities (Srbijagas, Jugorosgas, Pionirgas, DP Novi Sad Gas) and water utilities (BG Vodovod), with no disclosed customers outside Serbia.

The company's technical stack spans bellows, rotary, turbine, and ultrasonic gas meters, volume correctors, and an in-house LIS data logger system, complemented by telemetry solutions including the IMR Walk-by radio system, IMR Group Metering System (radio data loggers with GPRS backhaul), and an IoT-based remote meter reading module. It also operates an ISO SRPS 17020-accredited laboratory under the Serbian Accreditation Body for testing and calibrating gas and water flow meters, and holds ISO 9001, ISO 14001, OHSAS 18001, and ISO/IEC 27001 certifications. The technology differentiators center on metrological accuracy, integration of telemetry with metering hardware, and long-lifecycle battery-powered field devices (up to 10 years) with EX/ATEX certification.

KonvexGV generates revenue primarily through hardware sales of measurement equipment, telemetry/IoT solution sales, and accredited laboratory and testing services. Pricing is quote-based and not publicly disclosed. The go-to-market is a direct enterprise field-sales motion targeting industrial, commercial, and municipal utility customers in Serbia, supported by participation in the European Utility Week trade fair. The business is intentionally small (seven employees) and concentrated on a single-country, niche industrial distribution and services vertical with high regulatory and switching-cost barriers.

Scale indicators1 record

Recent moves1 record

Expansion highlights3 records

Direct peers

• Iskraemeco: Slovenian smart-metering manufacturer and AMI solutions provider with strong regional presence in SE Europe, including former-Yugoslav markets. Closely comparable in scale, geography, and product mix, and a credible alternative supplier for Serbian utilities.
• Diehl Metering: German-headquartered manufacturer of gas, water, and heat meters with full AMI/telemetry stack (IZAR). Directly comparable product portfolio across residential and industrial metering, and a competitor for the same Serbian utility accounts KonvexGV serves with Elster-branded hardware.
• Zenner: German manufacturer of water, heat, and gas meters including ultrasonic and smart/IoT variants. Comparable product line targeting residential and C&I metering with strong DACH and CEE presence, making it a direct competitor for Serbian utility tenders.
• Kamstrup: Danish manufacturer of ultrasonic smart meters and AMI systems for heat, water, and electricity. Offers a comparable integrated metering + telemetry solution and competes directly with Elster/KonvexGV for utility-side smart metering deployments in European markets.
• Apator: Polish group operating across gas, water, heat, and electricity metering with regional distribution and AMI offerings. Closely comparable as a Central/Eastern European metering specialist competing for the same utility modernization budgets that KonvexGV targets with Elster products.

Broad incumbents

• Itron: Global leader in gas, water, and electricity smart metering and AMI networks. Represents the largest direct competitive threat on the AMI/remote-reading side of KonvexGV's offering to large Serbian utilities.
• Landis+Gyr: Global smart metering and grid management incumbent with end-to-end AMI capabilities. Competes with KonvexGV for utility-side digitalization mandates, particularly as Serbian utilities pursue multi-utility modernization programs.
• Xylem (Sensus): Water and gas metering + AMI provider through its Sensus brand, now under Xylem. Competes with KonvexGV on advanced metering infrastructure and data management for utilities.
• Honeywell Elster: Global measurement and controls group that owns the Elster brand KonvexGV distributes. Functionally both upstream supplier and potential bypass risk — Honeywell/Elster sells directly to large utilities elsewhere, so the relationship also defines a competitive boundary.

Emerging players

• Baylan Metering: Turkish water and heat meter manufacturer expanding in CEE/Balkans with smart metering offerings. Comparable as a regional challenger pursuing the same utility modernization spend as KonvexGV.
