Float sensors are used to detect fluid levels and activate features to control the fluid level or flow.
Here is everything you need to know about these devices, so you are ready when you need to install one in your home or business.
Why They Are Used
The most popular reason these are used in pumps and machinery is that they prevent the liquid from contacting important parts and causing corrosion. Additionally, certain types, such as the ones in the ocean, can record information about the fluid and send it to a gauge or other reader.
How They Work
While some are very complex, such as the ones used by Argo, most sensors are fairly simple, with a ball, ring, or another object is used to sense the fluid level. The object sits on top of the fluid and moves up or down, depending on the level, which allows it to activate a feature when the fluid reaches a certain height or provide a reading on a gauge.
What Parts They Include
Typically, these units are made with a pipe or rod support, sensing object, switch to activate a function, wires to communicate with a gauge, and sealant to make the system waterproof. Sensors designed to activate a fluid level control measure will have a switch, while others will not. Similarly, those that act as a tank level gauge will have a place where you can read the fluid levels, while others may not.
You Can DIY Them
If you want to know the fluid level at your home or business, you can make your own basic sensor. There are plenty of basic plans that you can find online, although these will not provide you with as accurate information as the preassembled ones.
While you may expect these indicators to be complex, they are actually fairly simple. They are used in various pumps and machinery, work by using an object that floats on top of the liquid, consists of few parts, and easy enough some people can make their own versions.
