6 claims: 5 independent, 1 dependent

  1. 1
    I claim:1. A device for sampling a stream of fluid comprising a conduit having arranged therein longitudinally separated constrictions, a second conduit of smaller area than the first conduit arranged with an open end extending into said first conduit downstream from and facing one constriction and discharging into said first conduit on the downstream side of a constriction downstream from said first mentioned constriction, a plurality of constrictions in said second conduit, a third conduit arranged with an end extending into said second conduit downstream from and facing the upstream-most constriction therein and its other end discharging into said first named conduit, the point of discharge of said second conduit and of said third conduit being longitudinally separated with a constriction arranged in the first conduit between them, a constriction in said third conduit and means for removing fluid from said third conduit downstream from said constriction.
  2. 2
    A combined fluid sampling and metering device comprising, in combination, a conduit, means restricting the size of the stream arranged in said conduit, a. first and second orifice plate arranged downstream from said restricting means, a second conduit with an area corresponding to the opening in said restricting means arranged with an open end downstream from and adjacent to the stream of fluid passing through said restricting means and its other end- discharging into said conduit at a point between said orifice plates, a means restricting the size of the stream arranged in said second conduit, an orifice plate arranged in said second conduit downstream from said restricting means, a third conduit having an open end arranged in said second conduit downstream from and facing said restricting means and discharging into said first conduit downstream from said second orifice plate, means restricting the size of stream In said third conduit, and a tubing with an open end in said third conduit downstream from and facing the restricting means and a calibrated container arranged to receive the - discharge of said tubing.
  3. 3
    A sampling and metering device comprising, in combination, a conduit, agitating means arranged in said conduit, a means arranged downstream from and adjacent to said agitating means for causing the stream to converge and having CO an outlet arranged in the center of the conduit, a second conduit of smaller size than said first conduit arranged downstream from said converging means having its open end adjacent to and facing the discharge from said converging means, a first and second orifice plate arranged in said first conduit downstream from said converging means, the other end of said second conduit discharging into said first conduit at a point between said orifice plates, a means for causing the stream to converge in said second conduit and an orifice plate arranged downstream from said converging means, a third conduit of smaller size than said second conduit arranged with an open end downstream from and facing said converging means in said second conduit, and to discharge into said first conduit at a point below said second orifice, a converging means arranged in said third conduit, a tube having an open end downstream from and facing said converging means in said third conduit and a calibrated sampling chamber arranged to receive the discharge from said tube.
  4. 4
    A device in accordance with claim 3 provided with a conduit having an inlet upstream from the converging means in said first conduit, and discharging into said first conduit downstream from said second orifice plate, said inlet being arranged in the upper portion of said conduit and the conduit extending upwardly adjacent said inlet.
  5. 5
    A device for sampling a stream of fluid comprising a conduit having arranged therein longitudinally separated constrictions, a second conduit of smaller area than the first conduit arranged with an open end extending into-said first conduit downstream from and facing one constriction and discharging into said first conduit on the downstream side of a constriction downstream from said first mentioned constriction, a plurality of constrictions in said second conduit, means arranged to withdraw fluid from said second conduit, including a third conduit with an end extending into said second conduit downstream from and facing the uppermost constriction therein and fluidly connected to a vessel.
  6. 6
    A combined fluid sampling and metering device comprising, in combination, a conduit, means restricting the size of the stream arranged in said conduit, an orifice plate arranged downstream from said restricting means, a second conduit with an area corresponding to the opening in said restricting means arranged with an open end downstream from and adjacent to the stream of fluid passing through said restricting means and its other end discharging into said conduit at a point downstream from said orifice plate, a means restricting the size of the stream arranged in said second conduit, an orifice plate arranged in said second conduit downstream from said restricting means, and means for withdrawing a portion of the fluid from said second conduit, including a third conduit with an open end in said second conduit downstream from and facing said restricting means., arranged in fluid communication with a calibrated container.
