Sampling Systems

S32-LG Vent To Flare Configuration (F2)

The ability to purge the sample point ensures optimal retrieval of a representative liquefied gas sample. The S32-LG type samplers in vent to flare configuration provides a system purge in addition to sampling in a sample cylinder with a predefined filling rate. The predefined filling rate is achieved by using an expansion chamber. This liquefied gas sampler is equipped with an additional valve on the process outlet. Ensuring filling of the cylinder with liquid when difference between inlet and outlet pressure is significant. The unique design offers one-handle operation by multiple valves. These features provide sample accuracy, safety for the operator and the possibility of zero emission. This sampler type is suitable for liquefied gas and liquid with high vapor phase.

Install the sample cylinder and connect the flexible hose to the bottom side of the sample cylinder. Open the needle valves of the sample cylinder.

Turn the handle to the "process" position allowing the sample cylinder to be filled and the system to be pressurised.

Open the valve on the process outlet to allow a flow of liquid through the sample cylinder. To ensure a representative sample, this position can be held for any required time. Close the valve on the process outlet by releasing the handle.

Turn the handle to the "expansion" position. The internal connection between the sample cylinder and the expansion chamber has now been made. Maintain this position for any required time to enable the fluid to divide over the sample cylinder and expansion chamber. Close the two needle valves on the sample cylinder.

Open the valve on the expansion chamber. The expansion chamber and quick connects are being depressurised to the vent system. Release the handle to close the valve.

Turn handle to the "off" position. Disconnect the flexible hose. Remove the sample cylinder and connect the flexible hose to the top quick connect.
