CONE TYPE DIFFERENTIAL PRESSURE FLOW MEASURING APPARATUS

摘要

PURPOSE: A cone-type differential pressure flow meter is provided to prevent the lean of a cone without influencing to a flow by installing a supporter in the rear end of the cone, thereby accurately measuring a flow rate. CONSTITUTION: A cone-type differential pressure flow meter includes a cone(110). The cone includes: an enlarging inclination unit whose diameter becomes larger gradually to a flowing direction of fluid; and a reducing inclination unit(112) whose diameter becomes smaller remarkably to the flowing direction of the fluid. A press-roll hole(112a) is formed in an end portion of the reducing inclination unit. A cone is supported by a tube(130) so that the press-roll hole is positioned in the center of a pipe(120). The press-roll hole is connected to the outside of the pipe through the press-roll passage(131) of the tube.
