The Boyce MotoMeter was patented in 1912, and was used in automobiles to show the temperature of the radiator. From then through the late 1920s, the Boyce MotoMeter Company in Long Island City , New York, founded in 1912 by the German immigrant Hermann Schlaich , manufactured different models which varied in size and design.
For example, if the meter is set to a range of 300 V full scale, the meter's impedance will be 6 MΩ. 20,000 Ω/V is the best (highest) sensitivity available for typical analog multimeters that lack internal amplifiers. For meters that do have internal amplifiers (VTVMs, FETVMs, etc.), the input impedance is fixed by the amplifier circuit.
A heat meter, thermal energy meter or energy meter is a device which measures thermal energy provided by a source or delivered to a sink, by measuring the flow rate of the heat transfer fluid and the change in its temperature between the outflow and return legs of the system.
The primary purpose of the indoor-outdoor thermometer is to allow the outside temperature to be indicated inside a building, thus removing the need to go outside to take a temperature reading. They are also used in vehicles, and are particularly useful for municipal vehicles involved in snow and ice clearance. [ 5 ]
A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...
A modulated temperature differential scanning calorimeter (MTDSC) is a type of DSC in which a small oscillation is imposed upon the otherwise linear heating rate. This has a number of advantages. It facilitates the direct measurement of the heat capacity in one measurement, even in (quasi-)isothermal conditions.
In the modern usage, it is a device that from a distance determines the temperature of a surface from the amount of the thermal radiation it emits, a process known as pyrometry, a type of radiometry. The word pyrometer comes from the Greek word for fire, "πῦρ" (pyr), and meter, meaning to measure.
