Floating Piston cylinder means a metal cylinder containing an internal pressurized piston for collecting crude oil, condensate, or produced water samples.
Floating Piston cylinder for purposes of Appendix B, means a cylinder used for gathering produced water. The cylinder contains an internal piston controlled by gas pressure. The piston prevents sample liquid from flashing within the sampling cylinder and provides a means of extracting the sample liquid.
Floating Piston cylinder means a cylinder used for gathering produced water samples. The cylinder contains an internal floating-piston that is manually controlled by relieving inert gas pressure to introduce liquid. A Floating-Piston Cylinder is typically provided by a laboratory with the floating-piston pressurized to the closed position using inert gas pressure. As the inert gas is relieved from the cylinder, the cylinder draws in a produced water sample.
