v-cone flowmeter

main charateristic

Applications:

An outline of V cone flowmeter is a kind of differential pressure flowmeter by V cone sensor and pressure transmitter which is formed by the combination of various media, can be used to accurately measure the width of the Reynolds number {8*103 ≤ Re ≤ 5*107} within the scope of flow. The measurement theory is: because the actual fluid with viscosity, not ideal fluid, when the flow in the pipeline, in the premise of the full development of the flow, with laminar and turbulent flow of two kinds of state. According to the continuous flow of fluid energy conservation principle and Bernoulli's equation for fluid in laminar flow, the velocity distribution is a pipe center line as a parabolic symmetry, the pressure fluid through a certain pipeline drop proportional to flow. The V sensor in the measuring tube V cone mounted coaxially with the center line of the pipe. The measuring tube and V cone of the sensor is designed, precision machining. The fluid in the measuring tube through the V cone, to form a local contraction, flow in the V cone of flow velocity increases, pressure drop, the pressure difference before and after  in cone
