Abstract: A device for diverting liquid from a pipeline is described having a first conduit; a second conduit connected to the first conduit at at least a first location and a second location; with the second conduit having a first section to collect diverted liquid and a second elongated section adapted to contain at least parts of the diverted liquid with a hydrostatic head or level reactive to a pressure drop between the first and second location thus controlling flow of liquid from the first conduit through the second conduit by balancing the pressure drop with the hydrostatic head or level.

Abstract: There is provided a device for diverting liquid from a pipeline, and particularly for use with multi-phase flows where separation of liquid from gas is required. The device comprises a first conduit (50), a second conduit (52) connected across at least part of the first conduit, and means (80) for controlling flow of liquid from the first conduit through the second conduit by use of hydrostatic pressure. The first conduit is provided with an inlet (56) at substantially right angles to the first conduit. The second conduit further comprises an annulus (58) extending inwards from an inner wall of the first conduit and a lip (60) extending upwards from an inner circumference of the annulus. A number of embodiments of the device are described. The device is also suitable for fitting to flow meters to extend their range of operation.
