1 Answer

Answer :

Need of level measurement: In almost all industries, vast quantities of liquids such as water, solvents, chemicals etc. are used in number of processes. Liquid level measurements are widely employed to monitor as well as measure quantitatively the liquid content in the tanks, containers, vessels, reservoirs or liquid columns. The liquid level affects both pressure and rate of flow in and out of the container and therefore its measurement/ control becomes important in maintaining the overall process conditions. Hence improved level measurement accuracy makes it possible to reduce chemical process variability, resulting in higher product quality, reduced cost, and less waste.
