Level indicators are devices that are used to detect the level of liquids, powders and granular materials. These devices are used in numerous environments from small containers to lakes. There has been a significant advancement in sensor technologies; they are easy to use and portable. A liquid level sensing device can be placed on the wall of a container and within seconds an exact measurement will be displayed. Below we take a look at 3 different level sensors and their various applications.

Capacitance Level:

Capacitive sensors (M12)These sensors make use of radio frequency to measure fluids, solids, aqueous and organic liquids. The capacitance level indicator is portable, easy to clean and can be designed to withstand high temperature and pressure.





Optical Level:

Optical Level switchOptical sensors are devices that detect the level of liquids such as waste-water, grease and alcohol. The sensors use infrared light technology to measure the level of the liquid within a container. Due to the use of laser technology, these devices can be expensive compared to other level sensing devices.





Hydrostatic Level:

Hydrostatic - StainlessThese sensors are used to measure the level of water in open reservoirs, tanks and open bodies of water. Hydrostatic level measurement involves a submersible pressure transmitter that is completely immersed in the liquid that is to be measured.
