12 ABSTRACT OF THE DISCLOSURE A heat flux meter for measuring heat flux in a hot environment, such as, a coal-fired boiler, includes a cup-shaped body member of one-piece construction having an internal cavity in which is mounted an annular thermoelectrically-dissimilar member from that of the body member and in heat and electrically conducting contact with the body member. Electrically conducting wires of the same metal as the annular member enter the cavity and are connected to the centre of the circular portion of the body member and to the annular member. An e.m.f. is induced by the difference in temperature between the centre of the disc portion and the annular member. Since the body member is of one piece construction and the heat flux meter is sealed to the walls of the boiler, gases from the hot environment cannot enter the cavity and cause failure of the meter.
