Page 6: Section 1: Lgs-1 Sample Pump Overview
LGS-1 Liquid and Gas Sample Pump Section 1: LGS-1 Sample Pump Overview DESCRIPTION The LGS-1 Sample Pump is a pneumatically operated positive displacement pump designed to transfer samples of liquid or gas into a vented sample receiver or into a pressurized cylinder. The sampling cycle begins with a signal being sent from the controller circuitry to the solenoid which diverts instrument or plant air to the sample pump drive piston. -
Page 7: Section 2: Specifications
0.25 cc to 1.25 cc for liquid applications. The default factory setting for sample size is 0.5 cc at 300 psi using gas. Calibration is available when operating conditions are supplied by the customer. If an application requires sample volumes outside the standard ranges, contact Sensia. -

LGS-1 Liquid and Gas Sample Pump Section 3: LGS-1 Sample Pump Installation AIR SUPPLY The LGS-1 sample pump is actuated by an air supply. In gas applications, the line pressure is often sufficient to actuate the pump. But in liquid applications and some low-pressure gas applications, air must be supplied externally. -

Section 3: LGS-1 Sample Pump Installation Figure 2: Pump actuation (air) pressure chart TUBING CONNECTIONS Tubing arrangements will vary, depending on the product sampled (gas or liquid). At a minimum, ¼-in. stainless steel tubing will be required to connect the air supply from the controller to the sample pump. A ¼-in. -
Page 10: Fast Loop Considerations
LGS-1 Liquid and Gas Sample Pump FAST LOOP CONSIDERATIONS Under some flow conditions, a fast loop plumbing arrangement may be preferred to ensure that only fresh liquid flow is sampled. This configuration requires an orifice plate, flow straightener, or other flow obstruction in the pipeline to cause a small differential pressure to ensure that the sample probe collects fresh fluid with each sample grab. -
Page 11: Section 4: Setting Sample Size
Section 4: Setting Sample Size Section 4: Setting Sample Size Sample size is set by adjusting the knob at the top of the sample pump to a predetermined height (“h”) above the flat surface of the pump. The height measurement required directly corresponds to the sample size desired. - Page 12 LGS-1 Liquid and Gas Sample Pump 2. Locate the desired line pressure in the chart “CC” column of the Gas Measurement chart and note the corresponding height (h) value. Find the value (h) that corresponds to the desired sample size and line pressure.
