PURPOSE: To always accurately bring the inner face state of a monitoring tube into coincidence with that of a condenser tube and to extremely accurately know the inner face state of the real condenser tube by monitoring by measuring cooling wafer flow rate of a condenser body, calculating the flow rate per one tube, and so automatically regulating the flow rate of the cooling water of the monitoring tube in coincidence therewith.
CONSTITUTION: In the performance monitoring of the tube of a real condenser using a monitoring tube, when a variable blade opening meter 56 detects the flow rate of cooling water flowing in a condenser body 2, a flow rate controller 60 calculates the flow rate of the cooling water per one of condenser tubes 14 therefrom. An electromagnetic flowmeter 62 detects the flow rate of the water flowing in a monitoring tube 32. An electrolyte drive type regulating valve 66 sets the flow rate of the water flowing in the monitoring tube. The controller 60 compares the detected flow rate value of the tube 32 detected by the flowmeter 62 with the flow rate value of the water per one of the tubes 14 calculated by the controller 60, and controls the set flow rate of the valve 66 so that they coincide.
