Electromagnetic current meters of velocity

This bachelor thesis explains the issue of electromagnetic current meter of velocity. A survey of all available standards on these devices is carried out. Devices are described technically and metrologically. There are also described the possibilities of usage, operating conditions as well as problems of calibration of these devices. Information on available commercially available devices is provided along with a description of all relevant parameters. One selected device model is put to the test of measurement the velocity on the calibration tank of the laboratory, thus the experiences from real calibration measurement are gained and described
