What Mroz Engineering Co., Inc. does

Mroz Engineering Co., Inc., doing business as Meco, Inc. (and MECO Alarms), is a privately held, family-owned manufacturer based in La Mesa, California. Founded in 1990 by Kenneth Mroz, the company designs and produces intrinsically safe aboveground storage tank (AST) overfill and interstitial alarm systems for industrial liquid handling. The product portfolio is focused and narrow: two core alarm architectures — audible (non-lit) and audible/visual (lit) — each available in PVC or stainless steel components and in full-unit or head-only configurations, all certified to ANSI/UL 913 and compliant with NFPA 30A, UL 2244, and UFC requirements. Each unit operates on a 9V battery or 12V intrinsically safe line power, uses a float switch with a 12–20 inch adjustment range, and emits a 100 dB pulsating alarm at preset liquid levels. Supporting offerings include 9V lithium batteries ($11 each), custom logo silk screening (50-unit minimum), and interstitial alarm modifications ($23/ft above 24 inches).

The company generates revenue through one-time hardware sales at public price points ranging from $635 to $995 per unit, accessories, and light customization services, with bulk discounts available for orders of 5+ units. Distribution is hybrid: direct phone/email sales (619-466-1469) and appointment-based local pickup in San Diego, plus a network of preferred distributors — JMESales in the USA and Keller, Tanks Direct, and NEE in Canada. The customer base spans petroleum storage and fuel terminals, chemical and process manufacturing, wastewater and water treatment, bulk liquid distribution, agriculture, and energy/utilities, with named multi-decade relationships including Clawson Tank (tank manufacturer) and Tanks Direct (distributor). Meco markets through trade show presence at PEI and NACS events, blog content on petroleum industry compliance, Facebook, and email newsletter, and holds Petroleum Equipment Institute (PEI) membership. Leadership currently comprises second-generation family: CEO Renee Powell, VP/Sales Steven Powell, and Product Engineering/Manufacturing lead Hunter Jones. The company has no disclosed external funding, no acquisitions, and operates with 1–10 employees.

Broad incumbents

• Veeder-Root: Veeder-Root (a Danaher subsidiary) is the dominant supplier of automatic tank gauging (ATG) systems, including TLS series consoles used at petroleum storage sites. It overlaps directly with Meco's overfill-prevention function but offers a much broader continuous-monitoring and compliance-reporting platform; the most relevant broad incumbent in AST monitoring.
• Franklin Fueling Systems: Franklin Fueling (Franklin Electric subsidiary) supplies a full portfolio of fuel-handling equipment including ATG consoles (Evo series), leak detection, and overfill prevention for petroleum sites. Closest broad incumbent peer to Meco in petroleum AST safety.
• OPW (a Dover company): OPW Fuel Management Systems supplies nozzles, valves, vapor recovery, and tank overfill prevention devices for the petroleum industry. Directly competes with Meco's mechanical overfill alarm function as part of a broader fuel-handling equipment portfolio.
• Endress+Hauser: Endress+Hauser is a global leader in industrial process instrumentation including level, flow, and analytical measurement with significant presence in chemical and water/wastewater tank monitoring. Adjacent broad incumbent for industrial tank level monitoring.
• Emerson Rosemount (Level Measurement): Emerson's Rosemount level measurement portfolio includes guided wave radar, vibrating fork, and float-based switches used in industrial liquid storage including chemical and petroleum tanks. Broad incumbent with continuous level measurement offerings adjacent to Meco's point-level alarm.

Direct peers

• Pneumercator: Pneumercator manufactures tank gauging, leak detection, and overfill alarm systems for aboveground and underground storage tanks. Direct peer in industrial liquid level monitoring with overlapping hazardous-location product offerings.
• Scully Signal Company: Scully Signal manufactures overfill prevention systems, tank truck grounding, and vehicle detection products for petroleum and chemical tank applications. Most direct functional peer to Meco with similar focus on AST/tanker overfill alarms and intrinsically safe designs.
• Morrison Bros. Co. Morrison Bros. manufactures tank equipment including overfill prevention valves, vapor recovery, and alarms for petroleum storage tanks. Direct peer with similar mechanical overfill prevention and alarm focus for ASTs.
