Some of the biggest revenue generators for a country today are the food and beverages industries. Provisioning the markets with hundreds of items on a daily basis, it has become one of the most popular, highly effective and the busiest industries of the world. The current lifestyle of a modern day working man also demands to be provided with food which is readily eatable and easily available from everywhere. It does not mean that he demands highly of junk food, but he needs to have food available which gives him the energy to go on his work without feeling tired or exhausted.

Living up to the expectations of their customers is not easy for the manufacturers. As everything starts from the raw materials, the food and beverage manufacturers have to work round the clock to be able to provide everything which is demanded by their customers. It all starts by storing the materials in the highest quantity possible. The storage area of a food manufacturing industry is bigger than the halls where the goods are produced. And since the dry materials such as wheat and flour cannot be kept near water or in a place where humidity or dampness can harm it, the liquids are stored in a separate area for protection.

The high quantity of liquids is stored in huge containers, firmly tight with dedicated openings for the inlet and outlet and fitted with a liquid level indicator. The purpose of the indicator fitted with the storage tanks is to provide the staff with information about the amount of liquids present inside the tank or container. Since it is refrained to open the lid due to the fear of contamination's of germs and bacteria, the only source to get an inside look is through the liquid level indicator. As the needle drops on the lower area of the indicator’s gauge, the staff becomes alert and starts refilling the tanks.

To ensure that the factory doesn’t run completely dry from the necessary liquids all at once, the storage tanks are divided. Apart from the main tank which is gigantic, smaller tanks are installed which are fed by the main tank. The production lines are supplied with the liquids from these smaller tanks and whenever the smaller tanks become dry, the supply from the main tank is opened as a refill. During the process of refilling, the ultrasonic level indicator is used for accurate measurement and the new refill allows the production lines to continue with the production without a break in their flow.
