I was reading the discussions threads on density meter for slurries, the nuclear vs. non-nuclear options. the discussion is old and a lot of links have since closed. Starting a thread again to see what is the latest.
My own research -
- Nuclear : still used in ore slurries due to no technology being suitable to replace it
- Coriolis : not really used in abrasive slurries. I have seen them used in slurries like drilling mud (personal experience) and they are both very hard to manage and have too short lifetime. Perhaps the most diversified supplier base with Emerson/Micromotion, E&H, Krohne, and many others.
- Ultrasonic : there seems to be some development and a couple of companies that are targeting the slurries like rhosonics
- Vibrational : Old technologies from Solartron/Micromotion, plugging is a issue in their tuning fork. Inline instrument manufacturers like Rheonics have streamlined offerings that seems to do well, be focused on ceramic slurries, cement, drilling mud but do not see ore slurries - likely due to abrasion issues. I have had good experience with these in drilling mud.
- Vibrating tube: not really an option for most slurries
What have you been using and how is the process density meter world looking in 2026?
