PURPOSE:To individually monitor the flowing rate of oil in the forced circulation path at the monitoring areas by forming an oil flow monitoring apparatus with an individual display which is ON-OFF controlled with an oil OFF relay contact internally provided to respective of flow meter arranged in the side of induction apparatus and a total monitoring circuit which issues an alarm signal when at least one of a plurality of oil flow meters detects drop of oil flow rate. CONSTITUTION:An oil flow rate monitoring apparatus, comprising individual indicators 5A-5F which are ON-OFF controlled by the oil OFF relay contacts 1 internally provided in the oil flow meters of induction apparatus and monitoring circuits 6 9 which issues an alarm signal when at least one of the oil OFF relay contacts 1A-1F operates due to drop of oil flow rate, is installed in the monitoring areas different from the installation areas of induction apparatus. As a result, if drop of oil flow rate is generated even at the one of a plurality of forced circulation paths, it is informed by an output alarm signal of the monitoring circuit and the defective forced circulation path can be defined with the individual display.
