Engineered Components for Reliable Radiometric Measurement
Radiometric measurement is Ronan’s only focus. Our source holders, detectors and microprocessors are designed to work together in configurations that solve demanding level, density, weight and mass flow measurement applications in harsh process environments.
Built for Radiometric Measurement. Configured for Your Application.
Every Ronan measurement system is built from components selected to help solve the toughest measurement challenges. Source holders, detectors, and electronics are configured to work together based on vessel or conveyor geometry, measurement range, process conditions, required performance, and installation environment.
Ronan offers a wide variety of Source Holder and Detector configurations, including Source and Source Holders to meet every need. Detectors configurable to any shape or length, and a Transmitter that is compatible with all the configurations and can be customized for special applications. With a philosophy of designing new products to be backward compatible, our customers have the confidence of an installed base of thousands of systems.
HOW IT WORKS
Three coordinated components create one radiometric measurement system.
Ronan source holders, detectors and microprocessors work together as a complete system, with multiple configurations available to meet the specific process conditions and measurement requirements of each application.
Example of a Ronan radiometric measurement system shown with source holder, detector and microprocessor.
The source holder defines the measurement path.
Shield, contain and direct the sealed radioactive source. Multiple mounting styles, shielding capacities, materials, collimation options and shutter configurations allow the source holder to be matched to the application.
The detector measures the transmitted energy.
Detect the energy transmitted through the process. Detector configurations are available for different measurement ranges, installation constraints and demanding process environments.
The microprocessor converts the signal into process measurement.
Process the detector signal for measurement, calibration, compensation, diagnostics, communications and integration with plant control systems.
Cost of Ownership
Even though the initial equipment cost may be approximately 20% higher than conventional gamma gauges, the return on investment is almost immediate. The differential in equipment costs are offset by lower installation costs. RLL sources do not require licensed personnel to install, service or commission at their registered location. Whereas conventional source holders require licensed personnel. On-going maintenance costs are also lower as the RLL does not require periodic leak tests (RLL-1) or shutter checks as conventional sources do.
-
- The RLL-type Gauge is approximately 100 lbs (45 kg), lighter than conventional type Gamma gauges which makes it easier to install.
- Supports are not required for installation on smaller, lighter piping.
- The RLL source holder is also smaller in overall dimensions (6 in, 15 cm) than conventional type Gamma gauges.
Ronan’s exclusive RLL gauges are dependable and provide repeatable measurement while being easy to install, calibrate and maintain.
Ronan can utilize low-level technology because our only focus is on non-contact measurement gauges. We use scintillation type detectors and cut and polish the crystals at our facility. Spring pressure holds the crystal securely to the photo-multiplier tube. We do not use cements, glue or grease that can degrade or break the connection between the crystal and photo-multiplier tube. Ronan typically uses larger crystal sizes, which enables us to measure a larger sample of the product in the pipe. Ronan’s microprocessor utilizes the latest technology in the industry.
