What LARCO does
LARCO SASU is a French industrial equipment manufacturer founded in 1957 and headquartered in Argenteuil, specializing in safety, instrumentation, and automation solutions for liquid and gaseous hydrocarbon storage tanks. The company is a wholly owned subsidiary of the FINERGY Group and operates globally through direct enterprise sales and a trained agent network spanning 88 countries, with a presence on over 300 storage sites.
The product portfolio is built around three pillars: (1) safety equipment based on proprietary DOCIL optical-sensor technology for overflow prevention, leak detection, and level measurement (with sub-millisecond response and 1 mm accuracy), complemented by flame arresters, emergency vents, grounding reels (RGA750), and hydrocarbon separation valves; (2) environmental and performance equipment including COVERFLOTE internal floating screens (up to 98% evaporation reduction), ATEX-certified floating suction systems (T2000 rotary joint), geodesic domes, and compression-plate gaskets; and (3) automation and software via the SETMAT platform integrating DPPACK ERP with PLC-based depot automation, multi-protocol connectivity (Modbus, Profibus, Profinet, HART), and SCADA integration (PCVue). All safety-critical products carry ATEX, SIL 2/3, API, NFPA, IECEx, and ISO 9001/80079-34 certifications.
The business model combines hardware sales (sensors, screens, seals, valves, cabinets), professional services (audit, engineering, installation, commissioning, maintenance, training), and software/licensing revenue from DPPACK. Customers are primarily large oil and gas enterprises (TotalEnergies, Shell, BP, ExxonMobil, Sonatrach, Petroci), airport fuel operators (SFDM, Thappline), LPG distributors (Primagaz, Butagaz), and logistics groups (Bollore). Pricing is quote-based and project-driven, reflecting the customized, engineered nature of each deployment.

LARCO product offering
Product offeringCore offering
LARCO manufactures and commercializes safety, instrumentation, and environmental equipment for liquid and gaseous hydrocarbon storage tanks. Its portfolio includes optical overfill prevention probes (DOCIL series), hydrocarbon leak detectors, internal floating screens (COVERFLOTE), floating suction systems, breather valves, flame arresters, grounding reels, geodesic domes, and level gauging solutions. Through its SETMAT subsidiary, LARCO also offers an integrated ERP depot management platform (DPPACK) and loading dock automation systems.
Product overview
LARCO provides a comprehensive portfolio of safety, instrumentation, and automation solutions for liquid and gas storage tanks, serving oil depots, refineries, airports, and industrial facilities. The core offering centers on the SETMAT platform—an integrated ERP and loading dock equipment solution combining DPPACK software with specialized physical equipment. The product range spans three main categories: (1) Safety equipment including overflow prevention probes (DOCIL C400, C500 BTFO, C510), hydrocarbon detectors (DOCIL HK), flame arresters, emergency relief vents, and grounding reels (RGA750); (2) Environmental/performance solutions including COVERFLOTE internal floating screens, aspiration flottante systems, geodesic domes, and hydrocarbon separation valves; and (3) Instrumentation including level gauges, gauging solutions, gauge pads, and the Larco Safety Box control cabinet. All equipment integrates with the SETMAT ecosystem for centralized depot management, with multi-protocol communication (Modbus, Profibus, Profinet, HART) and compatibility with Schneider, Siemens, and other industrial PLC platforms.

LARCO competitors and assessment
Company assessmentDirect peers
- Magnetrol (AMETEK): Level and flow instrumentation specialist (now part of AMETEK) serving refining, chemical, and oil & gas storage. Directly comparable to LARCO on tank level measurement and overfill prevention products.
- HMT (Tank Gauging & Safety): Specialist in tank gauging, overfill prevention, and grounding equipment for aboveground storage tanks. Closely comparable niche player to LARCO with overlapping product categories in the storage tank safety space.
- VEGA Grieshaber: Specialized manufacturer of level and pressure measurement instrumentation with strong presence in chemical, water, and oil & gas storage. Closely comparable to LARCO's gauging and overflow prevention product lines.
- KROHNE Group: European-headquartered specialist in process instrumentation for level, flow, and analysis with strong refinery and tank terminal references. Directly comparable to LARCO's storage tank instrumentation portfolio.
Broad incumbents
- Honeywell Process Solutions: Provides integrated process automation, safety systems, and tank gauging solutions to refineries and terminals. Overlaps with LARCO on safety instrumentation, automation cabinets, and depot management software.
- Schneider Electric: Industrial automation platform provider (Modicon PLCs) that LARCO integrates into its Larco Safety Box and depot automation solutions. A potential competitor if Schneider expands into turnkey safety + gauging offerings.
- Siemens (Process Automation): Supplies PLCs, SCADA, and process automation platforms (SIMATIC) that LARCO integrates with. Competes on depot automation scope and could bundle its own instrumentation with automation to displace specialists like LARCO.
- Endress+Hauser: Global leader in industrial process instrumentation including level, flow, and pressure measurement. Direct overlap with LARCO's DOCIL sensor and gauging solutions for tank applications, with a much broader portfolio and global installed base.
- Emerson (Rosemount): Major instrumentation and process automation supplier through its Rosemount brand. Competes with LARCO on tank level measurement, leak detection, and overfill prevention for refinery and terminal applications worldwide.
- Yokogawa Electric: Provides process automation, safety instrumented systems, and tank gauging solutions to oil & gas and petrochemical customers. Overlaps with LARCO's automation, SIL-rated safety systems, and instrumentation scope.
