Level Indicators

The level of a liquid within a tank may be detected and measured using a level indicator. Floats, pressure or depth sensors, ultrasonic detection, and conductivity level measurement are all common level measuring devices.


How Do Level Indicators Work?


Level indicators employ a mechanical device, such as a float or a sensor with an output signal to display the level within a tank. Level controllers are simple indicators with an integrated control output allowing functionality such as on/off switching, alarms, etc.


Points to Consider When Selecting Level Instruments


  1. What is the material to be measured?
  2. Is the sensor to be placed inside or outside of the chamber?
  3. Do you need contact or non-contact measurement?
  4. What degree of accuracy is required?
  5. What are the pressure and temperature ranges needed?
  6. Is point monitoring or continuous measurement required?
  7. What measurement range is needed?
  8. What type of output is needed?
  9. Is there any build-up of dust or foam to consider?
  10. What is the material of the tank?
