Gravimetric level control is one of the most accurate inventory control methods available for measuring high-value solids, liquids and even gases inside tanks. Tank load cell is placed outside of the tank, which makes them superior to other measuring methods for aggressive, hot, frozen, non-free-flowing or non-self-leveling materials. Measuring results are not impacted by tank shape, load cell materials or process parameters, such as temperature or material viscosity.

Most tanks holding 10 kilograms to 1,000 tons or more are mounted on compression load cells or compression weigh modules for weighing. The RockerPin ensures the best accuracy in case of thermal expansion or contraction. Compression weigh modules are ideal for turning tanks into tank scales. In addition, smaller tanks can be mounted on bench or floor scales, which is convenient for legal-for-trade applications.

Tanks or hopper scales can be suspended from tension load cells or weigh modules, with accuracy similar to that achievable with compression systems. This mounting method can be convenient if an overhead structure already exists, or if the ground space under the scale must be kept clear. It is applicable for scales with capacities of approximately 20 kilograms (45 lbs.) to 30 tons.
 

Outdoor tanks must have safety features to protect the load cell during installation and operation. Tanks are exposed to wind forces. This requires features for weigh modules to cope with uplift forces on one side and extreme load on the other. Temperature changes can result in expansion and contraction of the support structure. Our weigh modules are designed to cope with such circumstances.
