Using liquids in the manufacturing process has become a normal thing among manufacturers. Many different chemicals are added during the manufacturing process to enhance the quality or some other aspect of the product. For instance, during the cutting process of marble slabs the machine uses water to keep the blades cool and a special chemical to enhance the shine within the slab. These uses and many others have forced the manufacturers to keep a huge stock of liquids in their storage areas. In bigger factories where production rates are much higher, the storage areas are bigger and expanded over a larger area.

The storage areas of the bigger factories have a separate place where the liquid storage tanks are kept and every storage tank is fitted with a liquid level indicator. The indicator helps the staff to know about the liquid level inside the tank. As the liquid storage tanks are huge, there is no safer way to know about the liquid level inside the tanks than to read the indicator. While the amounts of liquids increase every year due to a greater demand in the products being manufactured, the manufacturers are required to increase the number of storage tanks in their storage areas. No two different types of liquids can be kept in a single tank; hence it becomes necessary to keep a separate storage tank for every liquid inside the factory.

Since it is important to use different liquids for different purposes to reduce costs, it has become a necessity to have their supply in time. For instance as mentioned above that water is used to keep the blades cool, hence as an act to reduce waste and keep costs under control, because if the blade isn’t kept cool, dozens would be used within an hour and it will surely increase the costs. So using liquids has become necessary and this is the reason why the factories need to keep a stock of liquids available at all times.

To manage the liquids and ensure they are not wasted too, direct supply from the main tank is not provided to the production departments but they are allotted smaller tanks which are monitored by the ultrasonic level indicator. This indicator allows the staff to learn about the liquid being used in the production lines. As the smaller tank is enough to fulfill the daily quota, if any more is needed by the production staff, it will alert the management that the liquids have been wasted and this is why the production staff needs more than the allotted quota.
