Measuring liquids in tanks is important. However, measuring some fluids can be more difficult 
than others. As an example, tanks that hold liquid chemicals are especially difficult to monitor. Fortunately, there’s a way to do so with the help of float switches.
Selecting the Correct Float Switch
Measuring levels in a chemical tank is a tricky business. This is mostly because some chemicals can be caustic and may destroy a float switch made out of certain materials. That’s why it’s important to select a float switch that will be able to withstand the environment that it’s placed in.
Nylon switches, as an example, will be able to withstand oils, diesel, and organic chemicals. Polypropylene (PP) is suitable for acids and alkali, detergents, inorganic and organic chemicals, oils and water. Polyphenylene sulfide (PPS), however, is suitable for more aggressive chemicals.
Float Switches in Chemical Tanks
Why would chemical tank levels need to be monitored in the first place? There is a rank of reasons, and all of them go back to storing chemicals safely. When temperatures change, chemicals can react in different ways. It’s important to see if the liquid inside a tank increases or decreases in order to safely monitor the amount of fluid within a tank. In addition, it can be difficult to monitor the level of liquid inside a tank when caustic chemicals are involved. Having a float switch within the tank can help individuals determine how much liquid is within a tank without exposing themselves to what is inside.
Custom Float Switches for Chemical Tanks
Not all float switches meet all needs. That’s why sometimes you need to think outside the box when it comes to float switches for chemical tanks. There are many who decide to create a custom float switch to meet their needs for remote monitoring. Custom float switches can be made with materials that not on withstand corrosive chemicals, but also are designed to fit the specifications of the tank itself.
