| Welker CP-55EM Constant Pressure Transportable Sample Cylinder |
|
The Welker CP-55EM transportable constant pressure cylinder is designed to hold an exact representative sample from the pipeline flowing conditions, and in the same state, excluding temperature. A sealed piston is utilized in a honed cylinder with a precharge gas on one side that is 10 - 20 psi (70 - 140 kPa) above pipeline pressure. This precharge keeps a constant pressure on the product being sampled into the product side of the cylinder, thus keeping it in exactly the same state of condition as it is in the pipeline. The cylinder’s physical size and weight make it easily transportable in any situation.
