Measuring the liquids in a small tank is not a problem and there is not much care needed to be taken but when you talk about huge gigantic tanks which can hold more than just hundreds of gallons, measuring the liquids inside can be a huge problem. Coming near these towing tanks is a brave act in itself, but when you are asked to take measurements, the dangers can be too overwhelming. Taking the measurements is no child’s play because there are many chances of accidents involved. Since the safety standards set by the authorities deny any kind of operation to be done manually if it can be life taking, the factories have to use the liquid level indicator ultimately.

There are a lot of liquids being used in the factories at the same time. They are used for different purposes hence they need to be kept in different containers. Since these liquids are of sensitive nature and they cannot be stacked as if solids, they need different places to be kept safe and usable. Some of the modern factories have bigger storage areas than their production lines. The liquids inside these storage areas are provided the atmosphere they need to remain safe. In factories nitrogen is used in a large quantity for chilling purposes. It is not necessarily used in every factory set up on this planet, but most of the factories such as chilling plants use the chilled gas for instantly freezing the goods.

When there are too many people occupied in the same place such as is the case of factories, there is a huge risk of accidents. Some of the factories have been burnt to cinder due to a small mistake conducted by an employee. But the fire spread around so quickly that there wasn’t enough time to control it. According to the safety rules, a fire extinguisher needs to be present within human reach. In case of an emergency, the extinguisher shouldn’t be too far so that the fire may spread uncontrollably as the person just reaches an extinguisher.

These fire extinguishers are also measured on a routine basis just as the huge factory liquid storage tanks are measured. But since this is a small container and can be easily approached by a human being without fear of harming himself, the ultrasonic level indicator can be easily used to measure for accurate reading and flawless liquid level indication.  This handy device is easily carried to every extinguisher and the liquid level is noted and a record is created to make sure that in case of their need, the extinguishers are always in working condition.
