Course description

The course aims to transfer the basic principles on the construction and operation of test equipment to students, as well as the use of the main measuring instruments used on board. It provides an understanding of the basic concepts of metrological analysis, of the tools used for thermal, fluid dynamic, mechanical and electrical measurements.
Students must be able to independently choose the instruments and measurement techniques suitable for various applications in the naval sector. These choices presuppose the maturation, by the student, of a series of notions acquired during the course, both in classroom and through individual thematic insights.
To stimulate this type of learning, as well as the ability to communicate and convey information, the student is asked to develop a project to be discussed during the exam. The preparation of the project also favors the student's ability to rework information, to apply the knowledge acquired and to autonomously deepen specific themes.
Knowledge and understanding:
The student must demonstrate:
- to know and understand the fundamental principles of metrology;
- to know and understand the types of uncertainty and the propagation laws;
- to know and understand the functional characteristics of the measuring instruments and the principles of construction and operation of test equipment;
- to know the main instruments for measuring thermal, fluid dynamic, mechanical and electrical quantities.
Ability to apply knowledge and understanding:
The student must demonstrate that he is able:
- to apply the fundamental principles of metrology and the laws of propagation of uncertainties to real cases;
- to understand the main problems relating to measuring instruments installed on board;
- to know how to apply the principles of construction and operation of test equipment;
- to analyze the main characteristics of the measuring instruments, interpreting the technical data sheets and manuals, and to choose the most suitable instruments for specific applications.
Judgment autonomy:
The student must demonstrate that he has developed the ability to evaluate critically and independently the problems related to the measurement of the main thermal, mechanical, fluid dynamic and electrical quantities, and to be able to evaluate and minimize measurement uncertainties.
Communication skills:
The student must have the ability to explain, in a simple way, even to non-expert people, the concepts related to the measurement of thermal, fluid dynamic, mechanical and electrical quantities, as well as to the choice and use of the main measuring instruments and construction features and operation of test equipment.
Learning ability:
The student must be able to update himself continuously, through the consultation of texts and publications.


The students are required to have acquired and assimilated the following knowledge provided by the course of "Applied thermodynamics and thermal science":
- thermodynamics of states;
- balance of physical quantities;
- heat transfer.


(C1. 28 h, C2. 2 h, C3. 4 h) The international measurement system, measurement theory, generalized configuration of measuring instruments, measurement uncertainties and their classification, systematic and accidental uncertainties, type A and type B uncertainties, distribution of measurement results, analysis of uncertainties, propagation of uncertainties , calibration of instruments; thermoelectric thermometry, resistance thermometry, radiation thermometry, transducers, electromagnetic and ultrasonic flow meters, data logger, multimeter, voltmeter, ammeter, wattmeter; laboratory and case studies for on board measurements.
(C1. 8 h, C2. 10 h) Construction, functional and metrological characteristics of the measuring instruments, linear regression and least squares method, Pitot tube, hot wire anemometer, turbine flow meters, volumetric, vortex, thermal, humidity measurements, mass measurements, laboratory and case studies on the use of tools.
(C1. 4 h, C3. 4 h) Dimensional measurements, gauges, effect of the installation of flow meters on the pipes of a ship, laboratory and examples of hydraulic diagrams, reading and interpretation of technical and manual data sheets of equipment and instruments, laboratory and case studies.

The contents of the course concern the study of the basic principles on the construction and operation of test equipment, as well as the use of the main measuring instruments used on board. The course also includes laboratory activities. The course transfers the knowledge necessary to acquire some of the skills required by the International Convention STCW 2010 to access the professional role of Machine Officer, implemented from the DM MIT 19 December 2016 "Percorso formativo per accedere alle figure professionali di Allievo Ufficiale di Coperta e Allievo Ufficiale di Macchina", as amended by DM MIT n. 35 of 10/10/2018.
In particular, the topics covered in the course, which allow the students to acquire the competences required by the aforementioned decree for Machine Officers, are:
C1. Electrical, electronic and control equipment: 40 hours;
C2. Plant construction and maintenance features: 12 hours;
C3. Maintenance: 8 hours.

Teaching Methods

The training contents are transferred mainly carrying out lectures, exercises and laboratory activities. The teaching approach includes the stimulation of the student's curiosity regarding the knowledge of practical problems, and the development of the ability to solve them.

Learning assessment

The objective of the exam is to check the level of achievement of the course objectives previously indicated. The exam is divided into 2 parts:
- an oral test in which the ability to link and compare different aspects of the course will be evaluated;
- Discussion of the project developed by the student autonomously in order to evaluate the mastery of the topics dealt during the course.
