Measuring the level of solids can be a challenge. Due to the material properties, solids surfaces are usually uneven with irregular shapes, and there are usually high levels of dust. Along with these challenges, solid materials often have low dielectric constants making them hard to measure.
When selecting a measuring device, it is important to understand the purpose of the measurement. Solids measurements differ from liquid in many ways. There are different process characteristics to consider that may or may not require special features in the level device of choice.
