ABSTRACT:
A sample collector for collecting a sample of a gas-charged liquid such as a carbonated beverage from an exteriorly accessible transmission line through which the liquid is flowing. The collector comprises a cylindrical chamber for receiving and storing a liquid sample. A tube has a first end which extends inside the chamber and is positioned and configured so that liquid flowing therefrom is angularly directed against the inside wall of the chamber to create a downwardly-directed spiral flow of liquid along the inside wall. The second end of the tube has attached thereto a valve housing having a flow control valve and a forward end to which a bored needle is releasably secured. The needle bore and the tube bore are aligned and are in communication when the valve is open. The tube has a linear length and bore magnitude relationship which is conducive to inhibiting foaming of the liquid flowing therethrough for collection in the chamber, and foam production is further inhibited by the angular direction of the liquid flow against the inside wall of the chamber. To accomplish necessary tube length, the tube can be coiled on itself at a site along its length a plurality of turns to provide proper length and maintain an overall compact physical size.
