Abstract

PURPOSE: To make proper flow rate control possible, by providing a leakage detecting means in respective by-pass flow lines provided with flow rate detectors.
CONSTITUTION: Leakage detectors 30 and 31 and leakage detectors 32 and 33 are provided in by-pass flow lines 12 and 13 are by-pass flow lines 14 and 15 which connect the upper steam side and the lower stream side of resistors 6 and 7 provided in main flow lines 2 and 3. Now, when leakage of by-pass flow line 12 is detected, the flow rate signal of flow rate detector 20 provided in flow line 12 is cut by gate 40, and the operation of valve 4 controlled till now is stopped. Meanwhile, the flow rate signal from flow rate detector 21 in the side of indefectible by-pass flow lines 14 and 15 where leakage is not detected is output through gate 44 to control valve 4. Thus, proper flow rate control is possible even for break of the by-pass piping.
