What Ronan Engineering does
Ronan Engineering Company is a privately held industrial automation firm founded in 1959, specializing in radiometric (non-contact) measurement systems for process control. The company designs and manufactures measurement hardware, including density gauges, continuous and point-level sensors, weight and mass-flow measurement systems, mold-level systems for steelmaking, and radiation monitoring equipment, alongside radiation-shielded source holders (GS-400 fireproof, GS-200/300 stainless steel, SA series). Its underlying technology relies on radioactive source-and-detector pairs that are mounted externally to process vessels and pipes, enabling measurement in environments where invasive sensors would corrode or fail. The product portfolio is anchored by the Ronan Measure platform and the X96/X96S microprocessor-based transmitter family.
The company serves industrial process operators across 13 verticals, including fossil-fuel power, mining and aggregates, oil and gas refining, steel production, ethanol and renewables, chemical and petrochemical, pulp and paper, dredging, food and beverage, glass, cement, and recycling. Customers are primarily enterprise-scale plants facing extreme heat, pressure, corrosives, or abrasive solids where traditional contact sensors are unreliable. Ronan monetizes through custom-quoted hardware sales and recurring technical services including start-up, preventative maintenance, repair, radiation safety training, and licensing assistance for radioactive source ownership. Distribution is via direct factory sales from Florence, Kentucky, a sales/service facility in Sunderland, UK, and a global representative network spanning the U.S. and international markets.
After the December 2019 passing of founder John A. Hewitson and the January 2021 divestiture of its California Division (alarm annunciation, leak detection, and I/P products sold to Ronan Systems LLC), Ronan has refocused on its core radiometric measurement franchise. The company continues to launch new detector hardware (June 2025 Rigid Scintillation Detector) and participates in industry events such as CoalProTec, with no public funding, M&A, or IPO activity disclosed in the source materials.

Ronan Engineering product offering
Product offeringCore offering
Ronan Engineering manufactures and sells non-contact radiometric (nuclear) measurement systems for industrial process control, providing level, density, weight, point-level, mass flow, interface level, mold level, and radiation monitoring solutions. Systems are externally mounted on process vessels and pipes using radioactive sources and scintillation detectors, allowing accurate measurement in harsh environments with caustic, corrosive, high-temperature, pressurized, or abrasive materials. The portfolio is anchored by the Ronan Measure platform and X96 Series microprocessor-based transmitters, complemented by source holders, intrinsic safety barriers, and field service, licensing, and training offerings.
Product overview
Ronan Engineering Company provides radiometric (non-contact) measurement systems for industrial process control applications. The core product is the Ronan Measure platform, which encompasses multiple measurement types: Density Measurement System, Continuous Level Measurement, Weight Measurement, Point Level Measurement, Mass Flow Measurement, Interface Level, Mold Level System, and Radiation Monitoring Systems. These systems use radioactive sources and detectors mounted externally to process vessels to measure material properties without contacting the process media. The product portfolio includes the X96 Series microprocessor-based transmitters (X96S models for level, density, weight, mass flow, and mold level applications), X90 Series Point Level Monitors, XSD-1000 Gamma Radiation Detection Systems, X57 Intrinsic Safety Barriers, and various Source Holders. Supporting services include on-site measurements service, licensing support for radioactive materials compliance, and radiation safety training programs.

- AMETEK: Diversified electronic instruments group with process measurement and radiation-detection subsidiaries that overlap Ronan's density, level, and radiation monitoring portfolios. A potential strategic acquirer given its roll-up history in specialty instrumentation.
- Thermo Fisher Scientific: Major scientific and industrial instrumentation company with radiation detection and process measurement capabilities. Competes with Ronan's radiation monitoring systems and overlaps in process-level density and elemental measurement.
Emerging players
- Ohmart/VEGA (Ohmart Corporation): Legacy US specialist in nuclear/radiometric level and density gauges (now part of VEGA), historically a direct competitor to Ronan in harsh-service power, mining, and chemical applications across North America.
- Bin Master: Niche US vendor of level and inventory measurement for bulk solids and process industries, overlapping with Ronan's point-level and continuous level product lines in mining, aggregates, food, and ethanol.
