Abstract: Apparatus and methods are provided for thermal energy metering by measuring the average temperature of fluid in a tank, such as a hot water storage tank. Average temperature is measured with an elongated temperature sensor wire that can span the vertical height of the tank. The sensor wire can be protected with a waterproofing jacket.

Abstract: Method and apparatus for measuring temperature of a measured area of a surface without contacting the surface. The thermometer apparatus has an optical system which generates a correlative image of an infrared energy detector sensitive area at an image distance from the thermometer. A limiting aperture, having a size and a shape corresponding to those of the generated image, is between a mirror and the generated image. The measured area of the surface is between the generated image and the thermometer in use. With such a configuration, little infrared energy that does not originate from the measured area strikes the detector. Consequently, the energy reaching the detector is limited such that the size of the measured area remains constant, regardless of changes in the thermometer's field of view attributable to differences in the distance between the surface and the thermometer. A scan-and-integrate mode for practicing the invention is disclosed.

Abstract: A fast response temperature probe which may be used for a method for measuring an instantaneous temperature of a periodically changing fluid flow within a gas turbine is proposed. The temperature probe includes a substrate and a resistive element arranged at a surface of the substrate. Therein, at least at a surface of the substrate contacting the resistive element, the substrate comprises an insulating material having a thermal product of less than 1.5 kJ/(m2K sqrt(s)). The substrate or at least its surface is made from polyamide-imide such as for example fiber-reinforced Torlon© 5030. The temperature probe may allow measurements of instantaneous local temperatures of very fast fluctuations of more than 50 kHz at high spatial resolutions of, e.g., less than 0.5 mm2. The instantaneous temperature of a periodically changing fluid flow may be determined by correlating first and second sets of temperature measurements taking into account the periodicity of the periodically changing fluid flow.
