Q. How many detectors do I need for my level application?
A. The answer to this question depends on your measuring span and vessel diameter.
Q. How many sources do I need for a given measurement range?
A. It depends on your application. You need only one nuclear source for density and point level measurement. On the other hand, for continuous level measurement the number of necessary sources depends on the length of measurement span and the vessel diameter. Belt width and scale frame height determine how many sources you need for weight measurement. There’s no one-size-fits-all answer to this question.

Q. How can I use a density sensor to measure level?
A. All of our detectors measure radiation intensity and infer a process condition.“Density” detectors can be installed directly above or below a source to measure level. As the level rises, the product absorbs an increasing amount of radiation. Less energy hits the detector, so it infers a higher level.
Q. What hardware comes with detectors?
A. Different detectors have different hardware needs. We supply brackets for the electronics housing and supports for detector crystals used with continuous level detectors. We also offer a full range of pipe brackets for pipe-mounted density applications so you can get everything you need from one source.
Q. Is extra support required for mounting a source holder on a vessel?
A. Some source holders require extra support. We recommend tying off the source holder body, ideally at its center of gravity, to supports on the vessel when mounting longer units.
