Reducing wastes in the factories not only can help them save millions of dollars annually, but it will also be very helpful to protect nature. The high demand of products in the market has pushed factories in overdrive. They are working continuously round the clock only to stop for an hour or two that also for the break times. Working hours have been scheduled in such a way that every hour the machines keep rolling and workers are busy assembling. To keep the nonstop working routine effective, it has become common practice for factories to keep a huge supply of the necessary items in their inventory.

Most of the items come with an expiry date and hence they need to be consumed within the specified time. Most of them are never used because such a huge stock was never needed. What happens next? The expired stock gets thrown away resulting in huge monetary loss and piling the landfills with toxic materials. Liquids are flushed out in the drain pipes which mix with the sewer pipes. Since the sewer pipes often open up in separate landfills, even in rivers or open lands, the toxic waste of the factories contaminates everything. In an attempt to reduce overstocking and wastage, the ESH and production planning department work in collaboration to figure out the actual requirement.

The amounts of the required liquids are sent to the procurement department which contacts their suppliers accordingly. When the liquids arrive it is measured with a liquid level indicator to ensure that the exact amount has been delivered. It would help in updating the records which will be helpful in planning the production and setting daily targets. Since the exact amount that is needed will be procured, it will help to reduce the wastage that is flushed down the drains.

Sometimes the fixed liquid level indicators can malfunction. Since they are under constant pressure and even get old, they are often reported to malfunction. By showing wrong level of liquids, the production planning can be harmed. As targets would be set accordingly, the liquids would run dry in the middle of the process. For a secondary and better performing measuring device, the ultrasonic level indicator is sued. It is a portable device which does not need to be fixed at a single point, so one device is enough to manage the liquid measurements of an entire factory. This ability of the device has made it very popular among factory owners.
