The CLIF MOCK LGS-2000 Sampler is easily configured to sample product in proportion to time or volume using the CLIF MOCK True Cut LGS-1 Pneumatic Positive Displacement Sample Pump to collect product samples from the pipeline and deposits them into a low pressure receiver or constant pressure cylinder that can be transported for offsite analysis. CLIF MOCK True Cut LGS-1 Pneumatic Positive Displacement Sample Pump The CLIF MOCK True Cut LGS-1 Pneumatic Positive Displacement (PD) Sample Pump transfers samples into a vented sample receiver or a pressure-balanced piston cylinder. A purge valve manifold allows easy connection to process piping, including fast-loop connections. Sample size is set by adjusting the knob at the top of the sample pump to a predetermined height above the flat surface of the pump. The height measurement directly corresponds to the sample size desire.
