Abstract
Level sensors and instruments face a variety of end-user challenges due to
their suitability for diverse applications. Harsh environments and certain
peculiar substances for level sensing and measurement demand robust
instruments capable of highly accurate measurement. Both contact and non
-contact technologies have evolved technologically over the past ten years to
meet effectively both the substance level measurements and sensing
environmental hazards ensuring highly accurate point and continuous level
sensing and measurements. Manufacturers have developed a variety of product
variations to suit all substances and sensing environments for solids and
liquids both alike.
