Prerequisites
The Course deals with theoretical and application matters chiefly referred to the Teaching Fields of Hydraulic and Fluid Mechanics. It is useful for the students a preliminary frequency of the teaching Matters above mentioned, for an easier understanding of the object of the Course.
Learning outcomes
Show the methodologies used to perform laboratory and field measurements of hydraulic variables like pressure, velocity, discharge, water level. Laboratory and field application of some of the methodologies learnt in the course.
Course contents
Introduction
Theory of measurements, dimensions, errors definition and their statistical analysis.

Pressure measurements
Manometry and use of pressure transducers in dynamic measurements.

Velocity measurements
Measures based on mechanical principles (Pitot tube, vane anemometer); measures based on optical principles (laser anemometer (LDV) and its application to turbulence measurements); outline of PIV measurements. Ultrasonic techniques.

Water level and velocity measurements in free surface flow
Velocity measurements based on mechanical principles (use of current meter and their calibration); ultrasonic measurements.

Measure of discharge in open channels
Hydraulic measurements (weirs, broad crested weirs); discharge determination through local velocity measurements; discharge measurements using ultrasonic techniques.

Discharge measurements in pipes
Recall of traditional techniques and their applications (e.g. Venturi Tube); ultrasonic flowmeters.

Outline of hydraulic physical models and of measurement of the hydrodynamic coefficients.
