UA83107C2 - Device for flow rate of fluid medium - Google Patents

Abstract

The invention relates to measuring engineering and can be used for measurement of flow rate of fluid media in pipelines, mostly of liquids or gases in main pipelines. Device for measurement of flow rate of fluid medium through pipeline that has tubular body installed in pipeline, with inlet channel at frontal section for intake of inner medium, outlet channel of tubular body for outlet of medium to central part of pipeline, with plug for prevention medium leakage out of boundaries of pipeline and sensor of heat flow rate meter in tubular body, and that tubular body is made as such that it intersects long axis, the other end of the tubular body that is inside the pipeline is made closed, inlet channel has divided along all the frontal wall of tubular body aperture that is symmetrically placed with respect to long axis of pipeline and the output channel is arranged in central part of back surface of tubular body. So, in the device for measurement of flow rate of fluid medium distributions of rates, density, pressures, temperatures and viscosities of medium flow at whole cross section of pipeline are taken into account, and flow of medium is most completely coordinated with zone of the highest sensitivity of sensor, this leads to increase of accuracy and determination of flow rate of medium.
