There is no man or machine present today which can predict the future 100% but there are machines and gadgets which allow humans to make the best analysis for a short future (maybe months or a year to the maximum) and using these gadgets and devices, humans have gained the ability to manage some of the biggest challenges faced ever. One of these unbelievably accurate devices is the ultrasonic level indicator which is one of the most necessary devices to be present in a factory. Using the device, the staff can monitor the change of liquid levels in huge tanks and can predict how long will it take for the tank to run completely dry.

Liquids are widely used in the factories as they have various purposes. While water is one of the most widely used mineral all over the planet, to simply wash the entire factory on a regular basis hundreds of gallons of water is used on a daily basis. To simply store the water for cleaning purposes, gigantic water tanks are installed and the water is supplied to the entire facility through it. Powerful pumps are attached to the water tank and when the liquid level is recorded to be lower than is allowed, the pumps are turned on and the water is pumped all the way from the ground and into these towering, gigantic water tanks until they are filled to the brim again.

Apart from just this, water is used as an important ingredient in many processes too. Take the example of a beverage factory where thousands of bottles are filled and supplied into the market. There are more than a dozen machines which are constantly on the go and are pumping the liquid from the mixer into the bottles and then sealing them ready to be packed and shipped to the local stores. Water is the primary source of liquid in it and flavors are added to it to bring about the taste we all love to sip especially in this scorching heat. But it is emphasized to make sure that every ingredient is present in exactly the right quantity. Hence using the liquid level indicator, the water level is maintained in the mixer where all the other ingredients are added to the water and the mixer is turned on to completely mix the substances and the liquid becomes smooth. Now this liquid is filled in bottles and sold in the markets.
