One of the oldest materials used in the manufacturing faculties is none other than water. It is used in many different forms in the factories such as cleaning, washing, mixing and wherever applicable. Since it is a universal solvent, there are no limits to how many places it can be utilized. Since the factories of today have expanded to a huge area and the production levels have multiplied over time, there is a huge need of bigger storage tanks to meet the daily requirements. The huge tanks are capable to store thousands of gallons of water and the measurement of these tanks has become a bigger problem than before hence the need for a liquid level indicator is ever more than before.

In the past when the tanks were small and were mostly comprised of a couple of small storage drums, they could be measured by opening the lid and taking a look inside. As the needs of the factories grew, these storage drums became larger in size until they became a fairly big sized storage tank. In the early days the tanks were measured by the suspended chain. When the tank was needed to be measured, the chain which was suspended by a pulley on top of the tank would be lowered inside it through the lid. As it hit the bottom of the tank, the chain was again pulled out and the height to which it was wet was noted as the liquid level inside the tank.

This method soon became outdated when the tank’s size grew even bigger. The bigger sized tanks posed a threat to security of the person who would climb to the top and open the lid. As the tanks were able to store more water than two swimming pools, if the person who climbed to the top and opened the lid lost his balance and fell inside, there was a huge chance that he would have drowned. And cases like these have happened in the past a lot of times which was the reason to rule out the practice.

Today as the storage tanks are much bigger than ever, they are like small dams, the need for safer measuring devices was needed even more. The ultrasonic level indicator is the best option for measuring huge tanks because when measuring with it there is no need to open any lid or to let the liquid come in contact with the device. The ultrasonic waves by pass the walls of the container and measures the liquid’s level inside. The speed at which the entire process is completed makes it even more beneficent to the factories where speed is the most important aspect.
