ABSTRACT:
A piston-type portable sample cylinder is provided suitable for obtaining and transporting a liquified petroleum gas sample taken from a flow line. A piston slidable in a cylinder creates an increasing volume for the sample, and displaces an opposing inert gas maintained in the sample cylinder at a present pressure. A toroidal mixing element has an outer diameter approximating the inner diameter of the cylinder, and slides over a cylinder projection on the piston to minimize voids when the sample cylinder is empty. The piston may be provided with a selectively adjustable seal for maintaining sealing integrity over a long life, with or without the use of lubricants. Magnets on the piston for activating external magnetic trip flags may be contained in a nylon protector ring. Precision fill measurements may be obtained from a sight gauge including a biased coiled tape mounted within the pressurized inert gas cavity of the sample cylinder and secured to one end of the piston.
