Mettler-Toledo, Greifensee, Switzerland, points out that gravimetric level control is one of the most precise inventory control methods available. Its extreme accuracy makes it particularly helpful when measuring high-value solids, liquids and sometimes even gases.

Owingi to the fact that load cells are placed outside the vessel, it is perfect for measuring aggressive, hot, frozen, non-free-flowing or non-self-levelling materials. The company has put together a white paper on this subject providing the following information:
 

• Achievable accuracy with the gravimetric method
• Design of tank scales including understructure and piping
• Tank scale installation
• Weighing terminals and transmitters for tank weighing
• Characteristics of different calibration methods
• Maintenance of weighing technology for tanks.
   

The white paper is available in English, German, French, Italian, Spanish, Dutch, Swedish, Thai, Czech, Norwegian, Korean, and Russian.
