NOGS–ESP Hopper Continuous Level Measurement

How It Works

Based on the NOGS γ-ray detection technology, this device accurately detects trace amounts of natural radionuclides in fly ash by effectively identifying low-level gamma ray changes using random signal recognition technology.

Equipped with a specialized built-in processor, it gives accurate measurements by distinguishing between gamma rays emitted by fly ash and background noise. Unlike traditional ESP hoppers that rely on radioactive sources, the NOGS sensor (a scintillator) is unique as it functions solely as a detector, using fly ash itself as the gamma ray source. It’s especially useful for managing the first two ESP hopper fields, which handle the most ash.
