What Clark Reliance Corporation does

Clark-Reliance Corporation, headquartered in Strongsville, Ohio, and founded in 1884, is a privately held multidivisional industrial manufacturer specializing in level indication and control and filtration and separation products. Its portfolio is organized around two core capabilities: (1) Level Measurement Solutions, sold under the Reliance brand (boiler trim including gages, valves, columns, and indicators), the Jerguson brand (liquid level gage glasses, magnetic level indicators, level switches, and transmitters), and the Jacoby-Tarbox brand (safety sight glasses, sight flow indicators, eductors, and hygienic products); and (2) Filtration & Separation, sold through acquired brands including Anderson (mechanical separators, filter elements, HYCOA transfer valves), Oil Filtration Systems, and Enervac (transformer oil purification and SF6 gas servicing). Notable proprietary technologies include the Simpliport 180 Bi-Color Ported Water Gage Glasses with LED illumination for CCTV-readable remote monitoring, the Smart Level Eye-Hye technology, and the integrated LevelMax boiler level system that combines the two.

The company serves industrial buyers in over 120 countries across power generation, oil and gas (upstream, midstream, refining), chemical and gas processing, pulp and paper, mining and metals, food and beverage, pharmaceutical and biotech, and power distribution. Revenue mechanics combine (a) quote-based enterprise sales of integrated instrumentation systems under multi-year contract terms with (b) unit-priced OEM replacement parts and maintenance kits sold directly through the parts.clark-reliance.com e-commerce storefront with overnight delivery. Go-to-market is sales-led via local sales offices and a global rep locator network, supported by content marketing (case studies, webinars, document library), social media presence, and online specification tools (3D model builders, drawing tools, eductor sizing tool). The company operates 8+ wholly-owned subsidiary brands and maintains 251–500 employees; revenue is not publicly disclosed.

Direct peers

• Magnetrol International (Ametek): A leading manufacturer of level instrumentation (guided wave radar, ultrasonic, magnetic, and sight glass indicators) for process industries. Direct overlap with Clark-Reliance's Jerguson magnetic level indicators, Reliance boiler level gages, and Jacoby-Tarbox sight flow products across power, oil & gas, and chemical verticals.
• VEGA Americas (VEGA Grieshaber): Global specialist in level, point level, and pressure measurement instrumentation for process industries. Competes head-to-head with Clark-Reliance in process level indication for chemical, oil & gas, and power applications.
• KROHNE Group: Process instrumentation manufacturer specializing in level, flow, and analytical measurement. Direct competitor in industrial level measurement and filtration-related process monitoring serving the same heavy-industry customer base.
• WIKA Instrument: Manufacturer of industrial measurement instrumentation including level, pressure, temperature, and force products. Overlaps with Clark-Reliance's level switches, level transmitters, and boiler instrumentation portfolio for industrial process applications.
• Endress+Hauser: Global leader in industrial process measurement instrumentation, including level, pressure, flow, and analytical instruments. Direct competitor across Clark-Reliance's full instrumentation portfolio with broader geographic and digital capabilities.

Broad incumbents

• Emerson Automation Solutions (Rosemount): Dominant industrial automation provider whose Rosemount line competes directly in level, pressure, and flow instrumentation, and offers broader plant-wide automation solutions that bundle in level measurement — placing competitive pressure on niche players like Clark-Reliance.
• ABB Measurement & Analytics: Diversified industrial automation and process instrumentation supplier serving power, oil & gas, and chemicals. Overlaps with Clark-Reliance in level measurement and filtration analytics as part of a much broader automation portfolio.
• Yokogawa Electric: Process automation specialist offering field instruments (including level measurement) and control systems for oil & gas, petrochemical, and power customers. Competes with Clark-Reliance's instrumentation in process industry plants globally.
• Siemens Process Instrumentation: Major industrial automation vendor whose SITRANS line covers level, weighing, and pressure instrumentation. Competes with Clark-Reliance across power generation, water/wastewater, and process industry applications as part of a much larger automation suite.

Others

• Flowserve Corporation: Provider of flow control products and services for power, oil & gas, chemical, and water industries. While primarily a pump and valve specialist rather than level instrumentation competitor, it serves the same heavy-industry customers and overlaps with Clark-Reliance's sight flow and process level businesses.
