Homeowners with basements are always left with the worry that their premises could flood. But thanks to having a sump pump high-level alarm, that risk is greatly reduced. They’re also used in a variety of commercial settings for safety and production purposes.  

In this article, we’ll discuss everything you need to know about high level float alarms and why they’re critical in preventing flooding. 

What is a water level indicator alarm? 

A high-level alarm system alerts when the water level in a tank rises above a safe level. When this happens, a float inside the tank upsurges with the water and activates a switch, which then triggers an alarm to warn that action is needed. The alarm will continuously sound until the water level drops back down. 

How does a float alarm work? 

The float itself operates by using a buoyant alarm which rises and falls with the water level. It’s attached to a rod which moves as the water level changes.  

Inside the float switch housing is a simple mechanical electrical switch. As the water level increases, the float lifts the internal mechanism, which closes the electrical circuit.  

This completed circuit sends a signal to activate connected equipment, such as a pump or warning alarm. When the water level drops, the float moves back down, opening the circuit and deactivating the system – automatically switching the alarm off. 

What are high-level alarm float switches used for? 

In many industries, the ability to monitor liquid levels is crucial. Therefore, high level float alarms are used for multiple applications, including: 

Sump pumps 

Most commonly, float switches are contained within sump pumps, to prevent cellars and basements from flooding in low-level areas. As water naturally collects in the pump, the float switch activates to kick the pump into action when flooding may occur. 

Wastewater treatment 

Float switches play a key role in wastewater management. Much like those used with sump pumps, the switch activates when wastewater reaches a predetermined level. This means that issues such as blockages or pump failure are identified early to prevent flooding. In this environment, float switches also help reduce the risk of environmental contamination by stopping polluted water from overflowing. 

Industrial processes 

Float pump switches are also used in industrial settings, including food and beverage companies. In this instance, the device cleverly alerts workers that liquid ingredient levels are balanced in the creation of the final product. They’re also common in chemical processing industries, as the management of chemical liquid levels is crucial for health and safety purposes.
