METHOD FOR MEASURING COOLANT FLOWRATE IN NUCLEAR POWER PLANT CHANNELS Russian patent published in 2004 - IPC

Abstract RU 2228548 C2

FIELD: measurement technology; coolant flow measurement by means of various turbine- type flowmeters. SUBSTANCE: proposed method involves conversion of rotary motion of turbine-type flowmeter into set of electric pulses. Output signal is generated by polling set of electric pulses formed in the process with frequency higher than limiting value f>f_l, number of pulses during exposure time is counted, coolant flowrate is determined basing on G (n) dependence given in advance, where f_l. is limiting frequency; n is number of pulses counted during exposure time at f_l. ratio. EFFECT: enhanced precision of coolant flow measurement. 1 cl, 2 dwg, 1 tbl
