Quality control, the biggest challenge for the modern factories is what makes them win or lose the position in the market. This race is driving the manufacturers up the wall because they are not only required to manufacture quality products; they are also required to meet the huge daily production targets. In search to make products of superior quality with the least manufacturing costs, the ingredients have changed and a lot of different types of liquids, solids and gases are being used. Managing and storing the huge variety of products to be used in the manufacturing has created a challenge for the factories and raised many safety concerns.

Since it is necessary to have all the required ingredients in the largest quantity possible, the storage areas have been modified to make storage in bulk quantity possible. Huge sized and various shaped tanks and containers have been installed to hold the different liquids. Due to these massive changes, the need for a powerful and reliable measuring device became indispensable. Ultimately the need was fulfilled with the ultrasonic level indicator which is by far the most different and unique measuring device. It has the ability to not only measure liquids and gases; it has the unique ability to measure these materials without coming in contact with the materials.

This device has made it possible for the factories to use the sensitive liquids which are highly toxic and corrosive. As it is impossible for the humans to come near them without proper protection, the normal liquid level indicators also failed to perform their best with them. These indicators either started malfunctioning after a very short period, or they broke apart leaving the staff to note wrong readings only to realize when the gauge was still showing a plentiful level and in reality the tank was completely out of stock. As a result the quality suffered and the targets were nowhere near to be met for as long as the refill was unavailable.

Apart from these toxic and corrosive materials, to measure water level in the tanks the use of standard liquid level indicator is still applicable. If a factory has no use of sensitive raw materials, it can do without the ultrasonic measuring device. But if it needs to keep a stock of liquids other than plain water, it badly needs the ultrasonic liquid level indicator. Without it the factory would often be receiving complaints of missing out of necessary liquids and of broken or damaged liquid indicators.
