To manage a huge order supply of a merchant the production facility has to be equally capable of handling the order. The production facility has to have a horde of workers who can process the order effectively and meet the targets not only on a daily basis, but even every hour. Making production on such a huge scale a reality is no easy task and there is one crucial factor worth considering, and it is to manage enough stock of the necessary materials. Hence the huge production facilities have equally huge storage areas.

Since a lot of liquids are also to be used in the various phases, liquid management is a part of the storage areas. Liquids in large quantities cannot be stored in small barrels; hence the factories house a number of massive sized storage tanks. These storage tanks have a capacity to contain many thousand liters of liquids inside them. The task of managing liquids not only ends with providing an area for storage, it also needs to be measured consistently. Thus a liquid level indicator is used to measure these huge storage tanks.

Measuring the liquids is important basically for three reasons. The first reason is to keep a record of all the liquids that have been used. Maintaining a record helps in learning about the amount of liquids still available for further use. Knowing about the amount that can be used is important to plan out the daily targets for the production lines. Since production targets are made on a monthly basis, but they are regularly changed on a daily basis keeping in view the stock available for use. If some lines fall short in meeting their targets, a portion of their target is assigned to the line ahead of its target and the quota of the resources is also given to it.

The second reason to know about the availability of liquids and other materials is learning about the production costs. As the materials are used, the cost of the production becomes clearer to the management. It helps determine if the goods are being prepared within the budget. In case a product needs more materials than was originally planned, the client is informed and a price is negotiated. The third purpose is to know if the liquids are needed to be procured or it would be enough to linger the procurement for the next month. In many cases liquids are hard to measure by the standard gadgets and the ultrasonic level indicator is used. But no matter which device is used for measuring the liquids, these above three purposes are the real factors.
