The DDG3 is a nucleonic density gauge that is installed on the outside of a pipe - no shutdown required - to provide reliable data for robust process control: Key features include:

  • Non-intrusive measurement, for applications involving high temperature and/or highly toxic or highly corrosive materials
  • High performance microprocessor electronics, for reliable operation over the long-term
  • Sensitive scintillation detectors, for accurate measurement with lower strength isotopes
  • Rugged construction, for use in harsh environments
  • User friendly menu driven display, for easy set-up and calibration
  • Suitable for pipes up to 1000 mm in diameter
  • Auto source decay compensation, for enhanced long-term performance.
