摘要： A method is provided for measuring the mass flow of a stream of a gaseous medium of elevated first temperature flowing through a specific pipe. The method includes providing a reference stream of the gaseous medium with a known mass flow and a second temperature being substantially lower than the first temperature. The method further includes mixing the reference stream with said stream of a gaseous medium of elevated first temperature flowing through said specific pipe. The measure resulting temperature of the mixture of the reference stream and said stream of a gaseous medium of elevated first temperature flowing through the specific pipe is measured. The method further includes determining the unknown mass flow of the stream of a gaseous medium of elevated first temperature flowing through the specific pipe from the known mass flow of the reference stream; the elevated first temperature, the second temperature of the reference stream and the measured resulting temperature according to the formula: Mx = M ref  ( T   1 - T   3   x ) ( T   3   x - T   2 ) , where Mx is the unknown mass flow, Mref is the known mass flow of the reference stream, T1 is the second temperature, T2 is the elevated first temperature, and T3x is the resulting temperature after mixing.

摘要： The disclosure relates to a method for determining a temperature in a pressurized flow path of a gas turbine comprising the steps of sending an acoustic signal from an acoustic signal emitting transducer across a section of the pressurized flow path, detecting the acoustic signal with a receiving transducer, measuring the time needed by the acoustic signal to travel from the acoustic signal emitting transducer to the receiving transducer, calculating the speed of sound, and calculating the temperature as a function of the speed of sound, the heat capacity ratio (□) and a specific gas constant (Rspec) of the gas flowing in the pressurized flow path.Besides the method, a gas turbine with a processor and transducers arranged to carry out such a method is disclosed.
