Abstract
An apparatus () for determining thickness of refractory material () lining a metal vessel () is disclosed. The apparatus includes a radiation source () for emitting radiation through a metal wall of the vessel and into the refractory material, wherein some of the radiation is scattered by the refractory material, and a radiation detector () for detecting radiation scattered by the refractory material through the wall of the vessel. A converter provides an output signal dependent on the quantity of radiation scattered by the refractory material through the wall of the vessel and detected by the radiation detector.
