Level measurement devices can detect, indicate, and/or help control liquid or solid levels. Level measurement helps ensure the safety of workers, process equipment and the environment. Overfilling or underfilling tanks can lead to unfavourable outcomes, including hazardous spills, equipment damage, and accidents. Level measuring devices can be mechanical or electronic, and the type of device used depends on the material, its toxicity, and corrosivity. It can be used for continuous monitoring or point-level monitoring.
