Level Controllers

Level controllers are automated units for measuring the level of fluid in a contained area. They're used in systems that prevent liquid levels becoming excessively high or low.  


How do level controllers work?

Firstly, a sensor detects the fluid level in either a container or a natural setting, such as a lake. It then sends a signal – normally either pneumatic or electrical – to a control valve, solenoid, or other external control device. If the fluid level needs to be adjusted, the control valve will open or close according to the information it has received.


Types of level controllers

The two main types of level controllers are pneumatic and electric. Your choice of controller will depend on factors such as the type and density of fluid being measured, as well as the pressure of the container.

  • Pneumatic level controllers are preferred when the material is hazardous, or electricity is unavailable. 
  • Electric level controllers are useful in pressurised tanks and are generally very accurate and reliable. 

Level controllers measure either exact volumes or when fluid drops above or below a fixed point.
