LIQUID LEVEL/TEMPERATURE MEASUREMENT DEVICE

PROBLEM TO BE SOLVED: To enable an intake water temperature to be accurately measured even when the surface layer temperature of a sea area suddenly drops when measuring the intake water temperature at a power station, thereby reducing the suppression of unit output due to an increase in a difference of intake water temperatures.SOLUTION: A liquid level/temperature measurement device comprises: a cylindrical wind wave protective barrier 4 immersed in sea water S; a temperature measurement unit 12, disposed inside the wind wave protective barrier 4, for measuring the temperature of sea water just below a sea level Sa, and circulation means 20 for circulating sea water S inside the wind wave protective barrier 4 between a deep layer section 4d and a surface layer section 4s. By driving the circulation means 20 to circulate the sea water S inside the wind wave protective barrier 4, an attempt is made to equalize the temperature of the sea water S in the wind wave protective barrier 4, and it is thereby made possible to accurately measure the intake water temperature even when the sea water surface layer temperature of the sea water S suddenly drops.SELECTED DRAWING: Figure 1 【課題】 発電所の取水温度の測定において、海域の表層温度が急激に低下した場合でも、取水温度を正確に測定できるようにし、取放水温度差の拡大によるユニット出力抑制を少なくする。【解決手段】 海水Ｓ中に浸漬される筒状の風波防護壁４と、該風波防護壁４内に配置され、海水面Ｓａ下近傍の海水の温度を測定する温度測定部１２と、風波防護壁４内の海水Ｓを深層部４ｄと表層部４ｓとの間で循環させる循環手段２０とを備え、循環手段２０を駆動して風波防護壁４内の海水Ｓを循環させることで、風波防護壁４の海水Ｓの温度の均一化を図り、これにより、海水Ｓの海水表層温度が急激に低下しても、取水温度を正確に測定できるようにする。【選択図】 図１
