A computerized system for accurate, independent verification of natural gas fuel flow in order to control H2O injection flows. The H2O is injected into a combustion system to control emissions. The system comprises:receiving gas turbine control parameters from a gas turbine control system;receiving control parameters from a megawatt transducer;calculating values based upon readings from said control system and said megawatt transducer;comparing said values to a megawatt reference curve;detecting an abnormal reading;starting a timing sequence during which said reading is monitored;transferring NOx and H2O water injection control to a megawatt module at completion of said timing sequence;alerting operator said transfer;allowing for return of control to said gas turbine control system once said abnormal reading is corrected.
