Review on Liquid-level Measurement and Level Transmitter Using Conventional and Optical Techniques

ABSTRACT

Liquid-level measurement in storage tank system play an important role in industrial application such as in food processing, pharmaceutical industry, chemical industry, water purification system, petroleum industry and many more. Corrosive environments and turbulence can cause accidents and overflowing, taking a few of the conditions into consideration a measurement device must endure if it is to fulfil its goal of accuracy, linearity and dependability. So there are many well-established techniques to measure the liquid levels for different heights. In this paper, we have thoroughly reviewed the conventional as well as optical techniques of the liquid-level measurement and transmitting techniques of the measured quantity. Section 2 covers the different sensor designs while Section 3 covers transmitting technologies followed by conclusion in Section 4.
