LEAKAGE FLOW METERING DEVICE |
摘要 |
FIELD: coolant leakage flow measurement at damaged sections of nuclear power plant pipelines. SUBSTANCE: device designed to check heat and power generating systems of nuclear power plants incorporating reactors of all types for tightness by remote detection of leaks and measurement of their amount at certain distance from pipeline has a number of capacitive transducers of leak sound pressure spaced apart and disposed at certain distance from piece of equipment under check. Each capacitive transducer is connected through matching charge amplifier and voltage amplifier to display input. Transducer is polarized from dc power supply. EFFECT: enhanced reliability of leak flow checkup. 1 cl, 1 dwg
