A method and system for measuring a liquid level in a pressure vessel of a urea synthesis plant

Abstract

The invention is applicable in the field of equipment for urea synthesis process and particularly preferably in a urea synthesis reactor. The invention aims to provide a radar method for detection of the liquid level in a chemical reactor, which is more accurate, efficient and reliable than the prior art radar methods. The invention discloses a method and system for measuring a liquid level in a pressure vessel, the method comprising: transmitting an electromagnetic signal through a wave guide in the form of an elongate solid rod (5) with bottom end immersed in the liquid and detecting a signal generated by the reflection on the surface of the liquid.
