The gauge is comprised of a source housing that contains the radioisotope
source and the detector-transmitter that contains the scintillation detector
and electronics. Sources are available in a fan beam or strip source
configuration. For most fan beams, the beam angle spreads at a 45° angle in
the vertical dimensions. A 30° beam angle spread is available with model
5210, and 60° beam angle spreads are available with models 5205B,
5206B, 5207B, and 5208B.
Strips sources emit radiation evenly along the length of the vessel from the
source and measure the radiation level reaching the detector after passing
through the vessel walls and the process material.
The scintillation detector is available in lengths ranging from 1 to 12 feet,
in 2-foot increments. For a tall or narrow tank, multiple sources and / or
detectors might be required. Contact Thermo Fisher . The specific source -
detector configuration depends on the application. Three possible
configurations are illustrated below.
