Varec has supplied tank level gauging and inventory management systems to petroleum terminals and government fuel depots since 1947, and today operates as a specialist brand within Honeywell Process Solutions. Its FuelsManager software platform holds a dominant position in military fuel management, deployed across US Air Force, Army, and allied installations worldwide.
Company Overview
Varec was founded in 1947 in San Diego, California, building mechanical and later electronic tank gauging instruments for the petroleum and chemical industries. The company was subsequently acquired by Enraf, a Dutch instrumentation manufacturer owned by Delft Instruments, which folded Varec’s gauging and inventory management capabilities into its broader tank terminal portfolio. In 2011, Honeywell acquired Enraf from Delft Instruments, bringing Varec into the Honeywell Process Solutions division.
Honeywell elected to retain the Varec name given its established recognition across the military fuel management and petroleum terminal markets. The brand operates from Atlanta, Georgia, under the Honeywell Process Solutions structure, with product development, sales, and technical support integrated into Honeywell’s broader industrial automation portfolio.
Core Products & Technology
Varec’s product range centres on three interconnected capabilities: tank level measurement, inventory management, and SCADA integration. Its radar and servo-based tank gauging systems provide continuous level, temperature, and density readings across petroleum, chemical, and water terminal applications. These are deployed as standalone instruments or integrated with Varec’s software layer.
FuelsManager is the company’s flagship software platform, aggregating real-time inventory data from multiple gauging points and third-party instruments into a unified management interface. The platform supports custody transfer measurement, alarm management, regulatory reporting, and terminal-wide SCADA connectivity. Integration capability with terminal management system providers is a standard feature, enabling Varec deployments to sit within broader terminal automation architectures.
Servo gauging — Varec’s legacy hardware competency — remains relevant in custody transfer applications where high-accuracy level measurement is required for product handover calculations. Radar gauging handles bulk measurement across larger atmospheric storage tanks.
Military & Government Fuel Management
Varec’s strongest market differentiator is its position in military and government fuel inventory. The US Department of Defense operates fuel storage infrastructure across hundreds of domestic and overseas installations, and Varec’s FuelsManager platform is embedded in this network — including US Air Force and Army depot operations and allied military facilities. Government fuel management requires compliance with specific DoD bulk petroleum standards, real-time inventory visibility across dispersed sites, and audit trail reporting for regulatory and procurement purposes.
Few commercial inventory management products are configured to meet these requirements out of the box. Varec’s long-standing presence in government contracts and its understanding of DoD fuel accounting standards gives it an established position that competitors such as Endress+Hauser and Emerson have not displaced in this segment. This customer base also provides recurring software support and upgrade revenues that are less cyclical than commercial terminal contracts.
Commercial Terminal & Petroleum Applications
Beyond the government sector, Varec serves commercial petroleum terminals, refineries, airports, and pipeline terminals. At commercial sites, FuelsManager typically handles tank-level data aggregation, gain/loss accounting, and truck or vessel loading management. Airport fuelling operations — where inventory accuracy and reconciliation against aircraft uplifts are operationally critical — represent a recurring commercial application.
Refinery tank farms and pipeline terminal operators use Varec gauging alongside competing hardware from L&J Technologies and Motherwell Tank. In these environments, Varec’s integration into Honeywell’s Experion process control platform is a practical advantage — operators running Honeywell distributed control systems can extend inventory visibility without adding a separate vendor relationship. Varec’s position within the wider spectrum of tank equipment manufacturers reflects this integration focus, with gauging hardware increasingly inseparable from the software layer it feeds.
Varec in 2026
Within the Honeywell structure, Varec’s product roadmap is shaped by broader Honeywell priorities in industrial automation and digital transformation. FuelsManager has evolved from a local inventory platform toward cloud-enabled deployment options, with remote monitoring and centralised multi-site dashboards increasingly relevant to terminal operators managing geographically dispersed storage networks.
The LNG sector has expanded the addressable market for precision inventory systems — cryogenic storage introduces additional measurement complexity that Varec’s radar and servo gauging technology addresses. Honeywell’s parallel engagement in LNG infrastructure, including Honeywell’s LNG pretreatment technology for US export facilities, provides a commercial channel through which Varec instrumentation reaches new LNG terminal projects.
Competitors in the tank gauging and terminal automation space are consolidating. Endress+Hauser and Emerson have both extended their terminal management software capabilities, increasing competitive pressure on the commercial side of Varec’s business. The military and government segment remains more defensible given the embedded base and certification requirements.

What does Varec specialise in?
Varec specialises in tank level gauging systems and inventory management software for petroleum terminals, refineries, airports, and military fuel installations. Its FuelsManager platform aggregates real-time tank data for inventory control, custody transfer, and regulatory reporting across single-site and multi-site terminal operations.
Who owns Varec?
Varec is owned by Honeywell, operating as a specialist brand within Honeywell Process Solutions. Honeywell acquired Varec as part of its 2011 purchase of Enraf B.V. from Delft Instruments. Honeywell retained the Varec brand given its strong recognition in the military fuel management and petroleum terminal markets.
What is Varec FuelsManager used for?
FuelsManager is Varec’s flagship inventory management software platform, used to aggregate tank-level data from multiple gauging points, manage gain/loss accounting, support custody transfer calculations, and produce regulatory compliance reports. It is deployed at US military and government fuel depots and at commercial petroleum terminals worldwide.
Which industries use Varec tank gauging systems?
Varec tank gauging systems are used across petroleum terminals, pipeline terminals, refineries, airport fuelling operations, chemical storage facilities, and military fuel depots. Radar and servo-based gauging instruments are selected based on product type and the precision requirements of the application, particularly where custody transfer measurement is needed.
Who are Varec’s main competitors in tank level gauging?
Varec’s main competitors in tank level gauging and terminal inventory management include Endress+Hauser, Emerson (Rosemount), L&J Technologies, and Motherwell Tank. In the military fuel management segment, Varec holds an embedded position that commercial competitors have not significantly displaced, given DoD certification requirements and the depth of the existing installed base.
