Course Description

Performing successful experiments and knowing or estimating of the accuracy of measurements are very important for engineers. Therefore, all engineers should understand ‘measurement science’ if they want to study experimentally. Measurement Techniques in Engineering (MTE) course purposes defining basic concepts used in the measurement technique, statistical analysis of experimental results, curve fitting, and a rather broad range of instruments and experimental measurement techniques. This course consists of ‘introduction to the measurement and basic concepts used in the measurement field’, ‘statistical analysis of experimental data, types of experimental errors and error analysis, presentation of experimental results, and curve fitting’, ‘dimension, displacement, angle, and area measurements’, ‘pressure measurement’, ‘flow measurement (velocity and mass/volumetric flow rate measurements)’, ‘temperature measurement’, and ‘design of experimental setups, data acquisition, and data processing’ subjects.
