Many manufacturing facilities can house quantities of these types of containers. Others may only have one or two, but they may be critical to their operations.
Both the larger and smaller operations can run into significant problems if the materials become depleted. Therefore it is important to keep track of the amount of remaining material. Different types of instruments may be used for this purpose. In some cases, a liquid level tube will be sufficient. In other cases, a float device may be able to indicate the height of the contents within the container. But the most accurate and reliable method is to weigh the container and the contents.
Large floor scales are available for this purpose. These industrial scales are produced in a wide variety of different sizes. There is even one company, Arlyn Scales, that will manufacture a custom scale to any size required. Electronic scales display the weight of the contents on a digital indicator, which usually has the ability to subtract the tare weight of the container. Some digital scales also provide the ability to transfer these weight values into a computer system where they may be recorded for data analysis purposes.
The materials that are being weighed may have different corrosive characteristics. Arlyn Scales offers electronic scales from a variety of different materials. Whereas painted steel is usually the industry standard for floor scales, they coat the scale with a special protective epoxy. For more severe environments, they offer floor scales made from aluminum or even stainless steel. In all of these cases, the actual weight sensor is made from a high grade alloy of stainless steel. These provide years of trouble free use.
