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 ahoned cylinder with a precharge gas on one side that is 10 - 20 psi (0.7 - 1.4 Bar) above pipeline pressure. This precharge keeps a constant pressure on the product being sampled into the product side of the cylinder, thus keeping itin 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.

Features - Constant pressure design holds product in exact same    representative state as in the pipeline. - Equipped with ellipsoid gravity mixer. - All 316 stainless steel construction of pressure retaining    components with aluminum piston to facilitate handling. - Working pressure rating 2160 psi (149 Bar). - Volume indication by a hand held magnetic locator.
