The influence of V cone flowmeter scale deviates from the standard

Abstract: the influence of V cone flowmeter scale deviating from standard information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. V cone flowmeter of the flow coefficient and diameter ratio and Reynolds number parameters such as Red, and the scene is sometimes hard to ensure the parameters have been within the scope of the standard, so that when these parameters deviation occurs, will produce additional uncertainty. Here mainly to everyone. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the influence of V cone flowmeter scale deviating from standard article details. V cone flowmeter of outflow coefficient and diameter ratio & beta; Related to the parameters such as Reynolds number Red, and the scene is sometimes hard to ensure the parameters have been within the scope of the standard, so that when these parameters deviation occurs, will produce additional uncertainty. Here mainly introduce V cone flowmeter to everyone deviates from the standard parameters affect the main way: 1, & beta; The influence of the value under the first to introduce & beta; The meaning of value, in fact, everyone may & beta; All know a little bit more or less, be throttle diameter and pipe diameter ratio, after all, V cone flowmeter is the circular orifice and classical venturi tube under the combination. So V cone combines their advantages, also can measure the dirt medium, small pressure loss. Based on the theory of classical venturi, practical & beta; Should be controlled in 0. Less than 75, when & beta; Value greater than 0 because of improper design. 75, the flow coefficient of dispersion is larger, the uncertainty of outflow coefficient more than doubled. 2, the effects of Reynolds number Red V cone flowmeter due to its special structure, compared with the standard throttle device, the Reynolds number under limit had greatly improved, but also is not very limit. When the Reynolds number of unlimited dropped, V cone flowmeter of outflow coefficient decreases with the decrease of the Reynolds number, while its uncertainty will increase. V cone flowmeter as a new type of differential pressure flow meter, in recent years, the use of rising year by year, has a tendency to replace the standard throttle device, but are still a little limitations in high-pressure situations, because in the case of high pressure, pyramidal structure of the suction pipe under high pressure situation happens fall off phenomenon, so we can't blind production, manufacturing parameters to comply with the scene. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
