Development of Thermal Type Fluid Level Transmitter for Water Level Measurement of Containment Building in Nuclear Power Plant

원자력 발전소 격납 건물의 수위 측정을 위한 열식 레벨 측정기 개발

A new thermal type fluid level transmitter was designed and tested at the HITROL R&D institute. The relation of heat transfer and electric resistance was adopted as an operation principle. The length of a fabricated level transmitter was two meters and a water under normal temperature was used as a working fluid for the experiment Finally, the new product could have a high precision, acceptable accuracy and reasonable response time. Foreign-made level transmitter of this type is under in use for measuring water level of containment building in nuclear power plants so far. It is expected that new product will substitute it.
