DGN density gauge is used for on-line detection of the density (concentration) of various liquids. It provides real-time data to guide industrial production. It is also possible to indirectly determine the content of solids through the density value of the measured liquid.
DGN can be applied to:
Density detection of raw ore, concentrate and tailings of a mineral processing plant;
Density detection of flotation liquid in a coal preparation plant;
Density detection of various kinds of solutions in petrochemical plants.
1. Different from the traditional radioactive density gauges, DGN doesn`t use Cs-137 as the source but an exemption Na-22 source with 1*106Bq activity is used instead. With this low amount of activity and this special nuclide, this source is usually considered as an exempted radioactive source by most of the atomic energy regulatory bodies. It is harmless to human body and causes no pollution to the environment. Meanwhile, it also maintains the high stability as a radioactive source.
2. The detector of DGN adopts high-sensitivity and high-efficiency scintillator. With automatic peak stabilization technology, DGN`s detector can compensate drifts caused by factors such as temperature changes or component aging. It has extremely high stability and greatly reduces instrument maintenance cost.
3. DGN detects density at a non-contact mode. The detector and Na-22 source are installed outside the pipeline, they are not affected by the harsh conditions of material viscosity, corrosion, high temperature, high pressure and abrasion. It ensures the long-term operation of DGN is more stable, reliable and durable.
4. DGN can adapt to any environmental factors, speed and liquid temperature due to its radiographic measurement method.
5. DGN is suitable for installation in a variety of process environments, which greatly meets the needs of customers.
