This thesis deals with inductive flowmeters, specifically insertion inductive flowmeters. It examines in detail a blueprint of such flowmeter, consisting of probe, electromagnet, electrodes, exciting module and evaluation of signal. Gauging of a flowmeter designed this way, measuring data, charts, evaluation and interpretation. Consequent measurement in a calibration laboratory to elaborate, evaluate and interpret the results.

This thesis deals with the structural design of mass flowmeter based on the principle of the Coriolis force. The introduction explains how the Coriolis flowmeter operates, what types of flowmeters are currently being produced and what are the important parameters. There are appointed some of the principles that must be followed to the meter working correctly. It contains a proposal design of flowmeter for pipes DN80 and. Includes drawings for this design.

The thesis deals with systems for measuring the flow of milked milk. At the beginning of the work the history of cattle breeding in the Czech Republic is described as well as the process of milking, the issue and the principles of a flow measurement. The second part deals with certification from the association ICAR and with selected flowmeters, too. The main chapter includes the principles of selected flowmeters´ operation. The selected flowmeters of milked milk, which have been certified by ICAR, are described and compared here.

Diploma thesis solves how to create system for measurement of little liquid flows. The basic types of liquid flowmeter, which are possible used for measurement of little liquid flows, are described in the introduction part of thesis. The limit for little flow is often determined as flow 100 mg.min-1 and low. Second part of this thesis describes the ways of capillary production and practical experiments with them. Thesis is focused to thick film technology and LTCC technology. Next part of this work is solution of simple measuring unit for measurement of little flows less than 100 mg.min 1, which is controlled by microprocessor ATmega16. The measuring unit can be worked separately or can be connected to PC. The next possibility of flowmeter optimisation is summarized in end of thesis.

The main objective of this work is to create a program for automatic operation of measuring test track. The track is used for multi-hole velocity probes calibration. Normalized orifice plate is used as measurement standard. The program requires the user to enter certain information, which are not measured directly e.g. the values of measuring resistors, static air pressure. After entering this information, measurement can be started. The measurements are carried out simultaneously on the both flowmeters and on the thermomether Pt 100. The actual density of flowing medium is calculated from the measured temperature. Because the measurement is parallel, the calibrated flowmeter can be calibrated during the measurement.

Linearization display unit will receive pulses from a gear flow meter KRACHT whose frequency corresponds to a flow. The measured value is flow that nonlinearly depends on the temperature and viscosity of the medium. The dependency is described by calibration curves for each flow meter. The task of the diploma thesis is to design, implement, and verify the operation of the display unit, which calculates the actual flow rate from the input data (pulse rate, temperature, viscosity, and flow meter calibration curves). The device will contain a suitable user interface to display all measured values, inputs for connecting measuring sensors, and outputs for transmission of measured data. A part of the device will be a USB interface for configuration and uploading calibration curves from a PC application, which is designed by diploma student.

The diploma thesis analyzes the current situation of a flowmeters production company. Embraces the investment plan for a purchase of the construction hall including also calibration equipment. The second purpose is the expected opportunity to realize production in own facility. As the assignment of thesis we should target to formulate recommendations whether to realize the intended investment.

This thesis contains the description of well-known methods and principles dealing with the measurement of the flow-velocity of fluids. Furthermore, it contains the description of the development of the mobile flow-meter, including the realization and the technical description of the device. The thesis describes the advantages and disadvantages of the above mentioned flow-meter. The last part of the thesis is dedicated to the calibration of the device and to the possible practical use of the flow-meter.
