Design of Low Power Radar Level Sensor with Improved Accuracy Rate for Sodium Level Detection in PFBR

Abstract

The objective of this project is to design a non contact RADAR liquid level sensor combines high accuracy with low sensitivity to variations in air temperature and humidity but differs from other liquid level sensors in utilizing an unconfined radar beam aimed vertically downward to the liquid surface. The most notable advantage of radar sensors is their ability to measure liquid level remotely with no parts directly in contact with the liquid column. This non contact radar based liquid sensor is used to monitor the level of sodium liquid which is used as a cooling medium in nuclear combustion chamber of Kalpakkam nuclear power plant, which results in a significant reduction in system hardware components and overall installation and maintenance requirements.
