The invention relates to a fluid analysis module that comprises for blood analysis: a module housing with a fluid inlet port; at least one fluid sensor that is integrated within the module housing and comprises a sensor surface that is able to make a fluidic connection with the fluid inlet port; a chamber integrated within the module housing. The chamber can be brought into a fluidic connection with the sensor surface of the at least one fluid sensor. At least one first liquid reservoir attached within the chamber which is able to be brought into a fluidic connection with the sensor surface of the at least one fluid sensor; and at least one module housing surface, on which an elastic, fluid-tight separating wall that is embodied in membrane-like fashion is attached At least in portions, under a separating wall at least one fluidic functional configured as a flow valve and at least one fluidic functional element configured as a delivery pump is attached so that the fluidic functional elements are operable by local mechanical deformation of the separating wall: a) only deliver fluid from the fluid inlet port into the chamber via the sensor surface and b) only deliver a liquid housed in the liquid reservoir from the liquid reservoir into the chamber via the sensor surface.

A system is provided for testing and sampling of crude oil that includes a crude oil sampler system with a circulation loop and a water cut meter incorporated into the circulation loop. The system provides for a water cut meter positioned downstream of a sample withdrawal point. As the sample of crude oil passes through the circulation loop, the water cut meter can be used to determine the percentage of water cut of the sample. After passing through the circulation loop and determination of the water cut, a secondary sub-sample of the crude oil may be drawn off from a draw-off valve. The secondary sub-sample may then be sent to a laboratory or testing center for further testing or verification of the initial water cut.
