Checking the measurement capability of the flowmeters in the laboratory via ultrasonic sensors
Vítů, Martin ; Zachoval, Zbyněk (referee) ; Žoužela, Michal (advisor)
The main topic of the work is the theory of flow determination, in other words setting a flow rate using ultrasonic flowmeters. The relative dependence between ultrasonic and laboratory base inductive flowmeters was determined. Results of measurement are being used for intercalibration control of laboratory flowmeter rates. The work contains several tabular and graphical outputs of processed and evaluated data.
Metrological characteristics of current velocity meters using the electromagnetic principle of measurement
Vítů, Martin ; Brázda, Martin (referee) ; Žoužela, Michal (advisor)
This master’s thesis deals with the assesment of directional sensivity and accuracy of current stream velocity using electromagnetic induction meters in circumstances simulating the real measurement profiles condictions. The theoretical part of the thesis describes the issue of streamflow measurement in open channels and determination of the relevant measurement uncertainties. It also includes description of the hydraulic circuit and the subject current velocity meters. The experimental part of the thesis focuses on the effect of turbulence on the value and accuracy of measured velocity and directional sensivity of electromagnetic induction meters of current velocity. The results are compared with parameters given by manufacturers, research by other authors and with the metrological characteristics of hydrometric propellers, which are commonly used for streamflow measurement in open channels.
