Abstract:
The paper analyses the measurement accuracy of selected parameters, such as flow velocity and temperature, of a flowing medium, by means of the thermoanemometric method. The core of the method relies on the Wave Thermoanemometer System constructed by one of the authors. The sources of boundary error components are analysed within the signal conversion channels of the WTS. Errors are examined by means of relevant mathematical expressions representing signal conversion both in the velocity measuring channel and in temperature measuring channel. The algorithms have been developed for perfect and for real conditions. The theoretical considerations have been verified by laboratory tests performed by computerized equipment.
