Method for the measurement of gas and liquid flow rate and the electronic anemometer with the temperature wave

摘要

method of measuring gas flow speed and the liquid, employing temperature waves generated in the flow of, is that the flow generates a complex wave temperaturowu0105, consisting of two signals of a frequency sinusoidalnych redeployment phase, early by two resistive temperature transducers (n1 and n2).connected in series and placed in a mutually parallel distance (x) in the direction of current flow, with the wave temperaturowu0105 answering by a single detector (d) and the time (t) overall temperature signal (t) described dependence (a), where td - amplitude wave on the detector. - frequency of extortion.? - phase shift signals generated in the temperature transducers, is determined on the basis of phase shift and determined flow velocity of light (b). the subject of the invention is also an electronic termoanemometr wave temperaturowu0105.
