How Does A Water Level Sensor Work? Your Questions Answered
Monday, September 21, 2020

Water level sensors are one of those unsung heroes of our modern world. They allow us to automate the flow of water to and from every part of our lives. The United States Government has put an incredible amount of research into the science of water level sensors to make sure that we can make the most of this powerful technology.

Read on to learn everything you need to know about water level sensors!

What Is a Water Level Indicator?

The use of this tool is in the name! The water level sensor detects the level of water in some kind of container. It can then feed that information into other devices that control what happens to the water after that.

Without water level sensors, we'd have to have someone watch every tank of water we ever used and tell us when to fill or drain it.

Why Do You Need a Water Level Indicator?

The most obvious problem a water sensor can ward off is a water container that's too full or too empty. A water tank level sensor that shows that a tank is full can make sure that water doesn't keep filling the tank until it overflows into your home or your city.

On the other hand, a water sensor makes sure that we don't run out of water. If a container of water is getting empty, we can know that information automatically, and the system can automatically divert more water into the tank so we never run out.

How Does the Water Level Indicator Work?

The water detection sensor has basically three parts. It has a reference probe, a fill start probe, and a fill stop probe. You can place these probes at any height inside your water container.

If the water ever sinks below the level of the fill start probe, then the water level will automatically increase to fill up the tank. If the water level reaches up to the fill stop probe, then it will send a command to stop the flow of water.

Some water level sensor systems have even more probes than that. Some have five, and in certain cases, systems have even been made with seven probes or more.

All of these different probes will be placed at different heights inside the water container. As the water level reaches each probe, it will command the flow of water to increase or decrease by a certain amount.

By having more probes, the system can make more nuanced adjustments to water flow. Instead of simply flowing at 100% or at 0%, a system with extra probes can decide to have partial flow at various levels. This can make water flow systems more efficient.
