The factories today are much expanded and much advanced than the factories of the past decade. With the growth in technology, the demand of products has multiplied. People are more conscious about brands and the brands prefer to maintain their quality to keep the customers loyal to them. Today the war is not just of products, but it is of the brands and the quality they present to the public. To win the battle the manufacturers have to equip their factories with the latest machinery and the best staff. Deadlines are getting tougher with the race to launch a product at the right time, probably before a competitor launches his product and captures the better share of the market.

Business strategies keep changing and so does the trend in the manufacturing factories due to the change in marketing policies. The factories of today are converting from manual to automatic rapidly. We see a lot of artificial intelligence equipped machinery working in the factories such as the machine in the bottling plants and paint rooms of the car manufacturers. They have huge storage tanks that hold up to thousands of gallons of liquids to be used in the manufacturing process. These huge tanks, as being useful to the industry can also be the biggest threat if they spring a leak or a pipe bursts due to excessive pressure. Since most of the tanks hold highly sensitive and corrosive liquids, they often start getting rusty from the inside and then a leak is formed.

To avoid any unhappy incident, the tanks are regularly checked by a method known as the checking tightness of hatch with ultrasound. By this method the staff can check the quality of their storage tanks and if there is any kind of problem with the walls, the device picks it up automatically. The method to do is very simple. Once the tank is empty, the generator is placed inside the tank. Upon turning on the generator it starts to emit ultrasonic waves in all directions which are totally harmless to the environment, and the lid is shut tightly. The person conducting the test puts on the headphones and takes the receiver attached to a stick and starts scanning the entire tank from the outside inch by inch.

If there is any kind of leakage, small or big, the ultrasonic waves escape from it and are caught by the receiver and are heard on the headphones. The area can be marked and the repairmen would be called in to apply the repairs. After the repair work is done, the process, hatch cover ultrasonic tightness testing is again conducted to make sure that the work is completed in the rightful manner. Once the test is all clear, the tank can be filled with its liquid and be used again like it was being used before.
