Orifice meter scale expansion coefficient calculation method

Abstract: the orifice meter scale expandable coefficient method to calculate the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In order to obtain outflow coefficient, orifice meter measurement of gas. Necessary first to a certain level, first calculate the coefficient of expansion. For orifice flowmeter measurement on the spot, for gas, people tend to pay more attention to, expandable coefficient and Reynolds number. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the orifice meter scale may expansion coefficient calculation method of the article details. In order to obtain outflow coefficient, orifice meter measurement of gas. Necessary first to a certain level, first calculate the coefficient of expansion. For orifice flowmeter measurement on the spot, for gas, people tend to pay more attention to, has nothing to do but expansion coefficient and Reynolds number, the standard orifice plate for a given orifice flowmeter, and only & beta; The differential pressure and so on. Due to the fluid expansion cannot adopt the general formula of both axial and radial, the orifice meter. Calculated by the empirical formula. In accordance with the ISO5167 orifice pressure from three ways to use the same expansiveness coefficient formula, obtained by air, steam and gas medium, can be applied to other gases. Actually these theory, we don't need all understand, just need to know about it is good to have such a meaning, and the nozzle flowmeter and calculation formula of venturi tube flowmeter is different because he don't like orifice diversified expansion direction, only a single axial and therefore relatively simple point calculation formula. Introduced here is a little point in detail, considering the orifice meter is relatively widely. As for other correlation coefficient calculation throttling device, it can be with the company's technology department. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
