Abstract

A sample system for a fluid tank with an opening includes: a head unit, a sample vessel, a transport mechanism, and a controller. The head unit has a hollow body with a head connection that connects to the opening. The sample vessel includes a first sample chamber with a first sample valve disposed in a vessel body that fits within the hollow body. A first sample valve of the sample mechanism actuates to provide fluid communication to the first sample chamber. The transport mechanism connects to the head unit and the sample vessel, and moves the sample vessel between a home position and a first position. In the home position, the sample vessel is positioned within the hollow body. In the first position the sample vessel is lowered to a first level in the fluid tank, at which point the controller actuates the first sample valve.
