摘要（英）：

The invention provides a measuring system and a measuring method for water level of a nuclear power plant steam generator. The measuring system comprises a differential pressure transmitter, a condensation tank, a temperature instrument, and a digital water level calculating system. The temperature instrument is used to measure temperature T of water in the steam generator. The digital water level calculating system is electrically connected with the differential pressure transmitter and the temperature instrument, and is used to receive differential pressure signals and temperatures of the differential pressure transmitter and the temperature instrument, and calculate water level height in the steam generator. The measuring method is a method for measuring water level height in the steam generator by using the above measuring system. Compared with the prior art, the measuring system and the measuring method for water level of a nuclear power plant steam generator measure temperature of water in the steam generator through setting the temperature instrument, and use temperature signals to correct density of water and steam in the steam generator, so the measuring results of the water level of the steam generator are not influenced by density of mediums, and the measuring system and the measuring method achieve an objective of improving measuring precision.
