Radiometric Measurements and X-Ray Interference

10. February
X-ray interference with radiometric, or nuclear, instrumentation is a serious problem that can result in measurement errors and permanent damage to detectors. This white paper discusses users’ options for preventing errors, avoiding damage, and continuing to measure during X-ray interference events.

Radiometric responsibility from start to finish

A VEGA Field Service Technician installs a MiniTrac 31 onto a pipe where the plant required a crucial density measurement.
VEGA is committed to radiometric instrumentation from licensing to removal. When a Kentucky paper mill closed its doors, VEGA was there to help remove all the radiometric sources in the facility. When the plant was purchased by new owners, VEGA helped to guide them through the radiometric purchasing process.

Measuring density with a non-contact measurement: Application of the month

09. December 2019
A MiniTrac 31 density sensor is mounted on a vertical pipe to monitor the lime and asphalt mixture flowing upward. The measurement is made without interfering with the process or process material.
Asphalt shingles are made of fiberglass, asphalt, and ceramic-coated minerals. Fiberglass mats are run through a machine, coating the mats in asphalt multiple times. Near the end of the process, the ceramic-coated minerals are added for protection and color. The ratio of these two ingredients changes the asphalt mixture’s adhesive properties and its density, so a density measurement is critical for monitoring the adhesive properties of the mixture as it’s applied.

Modernizing radiometric measurements: A true story

11. November 2019
Radiometric instrumentation lasts a long time. A paper mill in the Upper Midwest understands this all too well. During a service call, VEGA Field Service noticed a number of old radiometric detectors, one of which had been in operation since 1966. Interested in upgrading their dated equipment, operators at the paper mill called the radiometric experts at VEGA to schedule a visit and learn about their options. Not long after the call, VEGA was at the mill’s doorstep.

Measuring rock flow on a conveyor belt: Application of the Month

01. July 2019
Mass flow measurements are a necessity at quarries, mines, paper mills, and power plants. These measurements are required for two main reasons: control and material transfer. Getting a reliable and accurate measurement ensures operations run smoothly without interruptions or slowdowns.

Radiometric mass flow measurement ensures precision charging in lime works

17. May 2019
The non-contact WEIGHTRAC 31 is ideal for harsh operating conditions and can also be relatively easily retrofitted to a conveyor belt.

Finding the optimum level in coke drums: Application of the month

02. May 2019
Coke drum
The delayed coking unit is arguably one of the most important applications in a refinery, and maximizing its efficiency with accurate and reliable level measurements gives operators the ability to safely increase throughput and minimize downtime. Since this is a volatile process in a large vessel with thick walls, radiometric instrumentation has been proven to be the best solution.

Security in every application

Every industry places very specific requirements on the measurement technology it uses. VEGA sensors reliably fulfil the most demanding measuring tasks.
