Aim of the course
The aim of this course is to provide basic knowledge concerning physical-technical measurement of:
- Temperature
- Flow rates
- Meteorological quantities like wind speed and direction, solar radiation, relative humidity, etc…
- Flue gas concentrations
- Electricity consumption
The course focuses on the description and working principles of the methods used for measurements of the above mentioned quantities and properties. Particular attention is paid to the physical description of the specific instruments and sensors. The course deals as well as with the description of practical applications in the field of environmental and energy engineering, providing the students with examples, case studies and simple economical analysis applied to measurements.
As critical and important part of metrology, the course covers as well as data analysis and estimation of measurement uncertainty and error. Finally, a particular section of the course is dedicated at covering the basic aspects of legal metrology.
Language
English
Expected results
After the end of the course the student should be able:
- To have a basic understanding of important parameters in metrology, like for example sensitivity and sensitivity error, measurement range, precision,accuracy, resolution, offset, linearity, hysteresis and response time
- To be able to select the right measurement instrument for a specific application
- To be able to carry out and install simple data collection systems for monitoring projects in the field of environmental and energy engineering
- To be able to process and assess the quality of measured data in the field of environmental and energy engineering
- To have basic knowledge of legal metrology, in particular addressed to metering of electricity, heat, gas and water.
