Level sensing of liquids and solids – a review of the technologies

Abstract

Purpose

Examines the wide range of liquid and solid level sensors, their technologies and commercial application.

Design/methodology/approach

Provides background information on trends in level sensing, on how each type works and the various applications. Some selection criteria are given.

Findings

There is a wide range of level sensors for every target liquid and solid sensing application, but the sector is technologically mature. There are some new application areas deriving from legislation and climate change.

Originality/value

Provides information of value for those involved with sensor applications.
