For use in a crude oil sampling system which delivers samples in pumped pulse fashion, a volumetric analyzer accumulating the sample is disclosed. In the preferred and illustrated embodiment, the device incorporates a valve which is selectively closed to direct the pumped pulsed sample into the apparatus. It includes a cylinder head attached to a cylinder. In the cylinder, there is a reducer sleeve. The reducer sleeve encloses a piston of selected size. The piston is forced upwardly by sample introduced beneath it. The piston connects with a push rod which in turn extends from the apparatus and which supports a piston follower having a marker cooperative with a scale to indicate the volumetric accumulation below the piston. The piston and reducer sleeve calibrate the apparatus to selected maximum capacities.
