The perfect level technology that works for every liquid level and point level application does not exist. Hydrostatic pressure has been around, it seems forever, and is proven in many applications. Non-contact radar and guided wave radar level instrumentation are popular and growing. Capacitance and conductivity have long histories of success in certain applications. However, it is still true that certain level technologies work better for some applications than other level technologies. This paper will explore a number of technologies for measuring liquid level and point level and will allow the reader to understand the basics of each technology with its inherent advantages and disadvantages.
This paper is available in its entirety, or in three separate parts. The first part of this paper focuses on hydrostatic level measurement. The second part focuses on continuous liquid level measurement utilizing newer technologies and the third, and last part, focuses on point liquid level measurement.
