The FTS consists of a sampler chamber with a spring-loaded valve on each end. A latching mechanism connects the valves together and holds them open. Above the chamber, there is a clock to program the valve closing time, and a ball operated tripping mechanism to release the valves. The lower end has a removable bull nose and ports to allow the fluid to enter. At the top, there is a rope socket for attaching wireline.
The sample chamber is lowered into the well with the valves open on each end, allowing well fluids to pass freely through the chamber at an interval programmed on the surface. At the surface-programmed interval, the valves close, trapping a sample, which can then be retrieved from the well. The sample is manually transferred to a suitable container under atmospheric conditions.
