Abstract
An apparatus for sampling a fluid from a flowline comprises a housing and a pressure control barrier moveably mounted in the housing. The apparatus comprises a sample chamber within the housing on a first side of the pressure control barrier and being fluidly connectable to the flowline for receiving a fluid sample from the flowline, and a pressure control chamber within the housing on an opposite second side of the pressure control barrier, wherein pressure applied within the pressure control chamber controls pressure of the fluid sample within the sample chamber. The apparatus comprises a guided wave radar device for determining a property of the fluid sample within the sample chamber.
Claims23
An apparatus for sampling a fluid from a flowline, the apparatus comprising:
- a housing;
- a pressure control barrier moveably mounted in the housing;
- a sample chamber within the housing on a first side of the pressure control barrier and configured to be fluidly connectable to the flowline for receiving a fluid sample from the flowline;
- a pressure control chamber within the housing on an opposite second side of the pressure control barrier, wherein based on a pressure applied within the pressure control chamber, the pressure control chamber is configured to control a pressure of the fluid sample within the sample chamber;
- and
- a guided wave radar device configured to determine property of the fluid sample within the sample chamber.
A method for sampling a fluid from a flowline, comprising:
- providing an apparatus comprising a housing, a pressure control barrier moveably mounted in the housing, a sample chamber within the housing on a first side of the pressure control barrier, and a pressure control chamber within the housing on an opposite second side of the pressure control barrier;
- fluidly connecting the sample chamber to the flowline and receiving fluid from the flowline in the sample chamber;
- controlling a rate at which the fluid is received in the sample chamber to expand the sample chamber and drive the piston member in a direction to reduce a volume of the pressure control chamber;
- and
- determining a property of the fluid sample using a guided wave radar device.
