The Computerized Boiling Point Heat Transfer Unit is designed to display the various types of boiling to change the intensity of the heat flow. The experiment is performed with environmentally-friendly, special low boiling point liquid. A transparent vessel allows to observe the evaporation process at the heated cylinder. More precisely, can be reproduced the nucleate and the film boiling and it can plot the so-called pool boiling which is the basis of the design of the systems with the steam boiler. The cylinder operates as a fire tube heated from the inside. An integrated water-cooled condenser allows for a continuous boiling process. The unit is supplied with manuals that describe each component of the system, installation and utilization procedures and give many exercises. The special liquid used evaporates at low temperatures. An automatic data acquisition and analysis system for Personal Computer allows to take the measurements automatically, to plot the curves on screen or print them out, to store the experimental data on disk or print them.

Four flowmeters are described below which operate on the principle of either head loss, impulse or velocity. A fifth flowmeter, Rotameter working on the variable area principle, is described separately in the Hydraulics Bench leaflet. The measurement of flow rate is a fundamental topic to which a considerable degree of attention has been paid with the result that there are flow meters available using a wide variety of principles. Chosen five types of flowmeter, which are all in common industrial use, to provide experiments in comparative flow measurement.
