Course content

Choice of methodology and instrumentation for determination of parameters such as velocity, pressure, temperature and chemical composition. Direct and indirect measurement of heat flux, volume flow rate, hydrodymamic forces and local fluid mechanical losses. Measurement of parameters in turbulent flow. Models and scaling factors. Calibration of measurement probes. Bias and random errors. Cross-correlation and auto-correlation of sample records. Measurement accuracy demands. Measurement system composition and sensor installation. Analysis and presentation of measurement data. Experimental results as a basis for mathematical modelling and verification of analytical and numerical calculations. Measurement planning and choice of instrumentation.

Learning outcome

The ability to measure and evaluate physical states and parameters, and to apply these for process control is crucial in industrial applications. The course provides a general introduction to measurement techniques widely applied in the process industry.

Learning methods and activities

Lectures and laboratory excercises. The graphical programming environment LabVIEW, which has become an industrial standard as a development tool for test- and measurement applications, will be used in the laboratory excercises. Introduction to LabVIEW will be given in lectures. Excercises are mandatory, constituting 20% of the final grade. The lectures and exercises may be in English when students who do not speak Norwegian take the course.
