Abstract
A sampling system for cryogenic liquid sampling which passes vaporized cryogenic fluid to an analyzer through a conduit having a defined restriction such as an orifice at or downstream of the input and which prevents choke flow in the conduit by simultaneously reducing the pressure which promotes choke flow and improving the ratio of the fluid pressure at and downstream of the restriction in the direction which resists choke flow.
