There are many ways of monitoring the amount of liquid in a tank. Pressure sensors give you high accuracy; ultrasonic sensors are contact-free but, the simplicity and low cost of a float switch cannot be beat. float switches monitor the level of liquid in a tank by using a float, magnet, and reed switch system that automatically closes and opens when water levels lower and rise within the tank.
Atlas Scientific offers plastic float switches for highly corrosive applications and stainless-steel float switches for food or drinking water applications. If you are looking for a simple solution that can easily integrate into your control system, look no further.
