Continuous level measurement
In continuous level measurement, the level of a medium in a tank or silo is detected and converted into an electronic signal. The level signal is either displayed directly on site or incorporated into a process control or management system.
The measured media are liquids, pastes, powders or bulk solids.

Discontinuous level measurement (Switching)
In discontinuous level measurement, a level switch detects when a certain predefined level is reached. Such a device is employed when it is not necessary to measure every possible intermediate level, as is the case with continuous level measurement. A switching command starts or stops filling equipment such as conveyors or pumps. Level switches outputting a binary signal can be integrated into a process control system.
Discontinuous level measurement systems can be used in liquids, pastes, powders or coarse bulk solids.
