Synopsis:

Methods of measuring state and process variables (a temperature, pressure, flowrate, velocity, density, viscosity, particle size, ...) and their conversion to electric signals including their processing. Application of measuring methods on machines of process and manufacturing industry (a heat exchanger, evaporator, dryer, distillation column, agitated reactor, ...). Analysis of processes taking place in apparatuses and diagnostics of apparatuses (tomography, RTD).
