Measuring the level of water in building tanks is an arduous task for the maintenance staff. Most of the time, the water tanks are either made of concrete as they act as better reflectors against heat or they are made of plastic. Nonetheless, their huge size is what poses the greatest safety risk to the person who is to measure the water level inside. The hugely sized water tanks can never be measured manually without opening the lid and taking a look inside. But consider a man hundreds of feet above ground level leaning over a water tank so huge it could easily drown him. It means nothing less than death for him.

In commercial and residential buildings where there are hundreds of homes and offices, the water demand is too high to be allotted to any one person. The building’s administration department handles the filling of the water tanks when the levels get lower. To keep a notice of the water level in the huge tank that can store up to a thousand gallons, the Ultrasonic liquid level indicator is installed. The indicator is often fitted right to the main pipe that goes from the tank to the houses and offices. But in some modern buildings, another indicator is installed in the maintenance staff’s room so that they do not have to go to the roof every time to check the water levels.

Most of the modern water level indicators now have a buzzer fitted in them. When the water level drops below half or nears empty, the buzzer goes off. This alerts the staff and they can turn on the powerful pumps to pump water into the water tanks. Considering the huge size of the water tank, it can take hours to fill it completely so the staff never takes the risk to let it go dry. They have mostly adjusted the buzzer to go off when the level is half or at least 25% of water level is still present.

Unfortunately most of the mechanical water level indicators are reported to malfunction. They either become erratic after sometime, or they get stuck to a single level. This confuses the staff and the building can go completely out of water. To avoid any chaos of the type, almost every building’s administration office has provided an ultrasonic level indicator to its maintenance staff. If they feel that the indicators in their office are malfunctioning, they can confirm it with the help of the ultrasonic level indicator.
