How does radiation-based level measurement work?
Radiometric or radiation-based measurement sounds complicated, but it’s relatively easy to understand. An isotope with low radiating intensity is housed inside source holder on one side of a vessel or pipe. The secure source holder collimates the energy so it is directed only at a detector mounted on the opposite side. As material fills the vessel, less energy reaches the detector which outputs an inferred level measurement.
What are the advantages of radiometric instruments?
Radiometric sensors are used for continous level and point-level monitoring in the most difficult solids and liquids applications. The reason for this is nuclear gauges provide a non-contact measurement that delivers accurate readings without touching the process material, so there is no chance of damaging the detectors with harsh, abrasive or corrosive products that would require frequent and expensive maintenance. External mounting has the added benefit of allowing for installation during ongoing production.
