Application solutions for continuous level measurements. Systems use non-contact technology keeping all system components not wetted to the process. This design enables continuous level measurements on processes with conditions of extreme temperatures, high pressure, corrosive, abrasive, and toxic. Often the measurement is not compromised by process changes in temperature, pressure, and density.

The system consists of a low energy gamma ray emitting source, detector, and microprocessor. Mounting is dependent upon the vessel shape and size; and is most commonly either external to the vessel or in sealed wells inside the vessel. The source and detector are mounted to opposing sides of the vessel allowing the process to fill between the two components. As the process fills the vessel, the gamma energy can not penetrate the process so the signal reaching the detector is reduced. This signal is correlated to a level measurement, displayed in selectable units of measure, and outputted at the microprocessor.
