Introducing the candidate with the principles of process measurement and control of the process using the measured values. After the course candidates will be capable to independently perform statistical processing of measurement results and evaluation of measurement uncertainty. The process of accreditation of laboratories and regulatory organizations.

Upon completion of the course is expected that the candidate is familiar with the basic measurements and instruments used in measurement and control in process systems. Also it is expected that the student is able to independently plan experimental measurements and work in laboratory and also to evaluate the measurement uncertainty. Basic knowledge about the accreditation of laboratories candidate receives through the consideration of the basic requirements of relevant standards.

Basic concepts of measurement and control in the process industry. Basic measurements in the process industry. Temperature measurements. Measurement of pressure and pressure differences. Measurement of fluid flow. Types and operating principles of sensors. Other measurements in process industry: weight, level, concentration, humidity, fluid physical properties (density and viscosity). Determination of the composition of gases and concentration of particulate matter. Complex measurement systems with data acquisition. Analog and digital signals. Transferring data to a computer. The formation of the control algorithm. Basic principles of operation of the SCADA software. Application of PLC's control. Measurement error. Statistical analysis of measurement results. Traceability of measurements. Calibration of measuring instruments. The concept and method for determining measurement uncertainty. Metrology laboratories and laboratories for testing and calibration. Methods and requirements for achieving the technical competence of laboratories accredited according to SRPS ISO/IEC 17025:2006 and SRPS ISO/IEC 17020:2002

Examples of certain measuring devices, devices for data acquisition and control. The realization of individual measurements in the laboratory (practical laboratory work). Processing of measured data and values and estimation of measurement uncertainty. The physical basis of determination of the measured values. Mathematical expressions that describe the phenomena that are used to process measurements. Methods of temperature measurements, pressure and pressure difference, flow metering using orifice plate, speed measurements of gases analysis. Complex systems of measurement and control of process systems. Methods for determining the measurement uncertainty. The process of laboratory accreditation.

The subject is optional. No special requirements for attending the case.
