There’s a ton of different ways to read water level. Pressure sensors give you high accuracy; ultrasonic sensors are contact-free but, the simplicity and low cost of a float switch can’t be beat.

Sure, there are a lot of crappy float switches out there, but don’t worry; over the years, we found the ones that work. We use these float switches all the time in our own lab, and we thought you might like them as well.
