Claim:
1. A fluid flow sampling device for positioning in a fluid conduit, comprising: a housing having a fluid inlet and a fluid outlet longitudinally separated from one another along an axis of the housing, the fluid inlet positionable in a middle third of the fluid conduit; a coalescent filter disposed between the fluid inlet and the fluid outlet to allow a sampling portion of fluid to pass through the filter and to allow a bypass portion of the fluid to flow past the filter and out of the fluid outlet to carry away coalescent material from the filter; a sample outlet port comprising a fitting coupled to the sample outlet port configured to allow for removal of the sampling portion of the fluid from the sampling device for sampling; and a sleeve disposed in the housing that is movable to block or allow flow through the fluid inlet and the fluid outlet, the sleeve comprising a lateral conduit corresponding to the sample outlet port, wherein when flow is allowed through the fluid inlet, the lateral conduit is aligned with the sample outlet port to facilitate removal of the sampling portion of the fluid from the sampling device.
