The chemical industry is thriving in business due to the increased demands of different chemicals both liquid and solid by the manufacturers. As the global demand for products increases, the use of plastic has increased by a huge magnitude and since almost all of the products are made of plastic, the use of chemicals used in plastic manufacturing is increased. There is no limit to the chemicals that can be used in manufacturing processes. In fact, a lot of manufacturers use various chemicals to bring out the shine or to make their products stronger.

In a documentary, top automobile manufacturer revealed to use cyanide while producing. The entire chassis of the car is dipped in a huge tank containing cyanide. The application of liquid cyanide on the body of the car helps to retain paint in a better way as disclosed by the manufacturer. Similarly a lot of other manufacturers also make use of highly toxic and sensitive liquids to bring about perfection in their products. The use of chemicals is a norm in the textile industry which is used to from start to finish. As a tool to control chemical wastage in the factories, the liquid level indicator is used to measure the amount of liquids being used and also present in the reserve tanks.

Since chemicals do not come cheap, it is necessary to put a control on its usage in the production process. The workers can be utterly negligent when working and the chemical can get contaminated. Contaminated chemical is of no use in production because it clearly loses its properties when another substance is added in it. This is another reason why the storage tanks are made keeping the chemical properties in view when a new chemical is being added to the line. A lot of chemicals are highly corrosive and can eat up the walls of storage tanks made of steel. This is why special alloy tanks or plastic tanks are used with the chemicals that are capable to eat up steel by reacting with it.

During the production process, such as stated in the above example of the car manufacturer, the storage tanks in the production hall cannot be measured by a normal indicator. As the liquid splashes and creates ripples, the normal indicator can clearly give false readings. Any change in the liquid level can result in the product to become faulty or lose its high quality. That is why with the help of an ultrasonic level indicator the liquids in motion are measured.
