Page 8: Installation & Operation
1. Welker recommends that the probe be installed in the top of the pipe and inserted into the center one-third (¹⁄₃) of the pipeline in a location where the product is well-mixed and will yield an accurate and representative sample. - Page 9 Using a crescent or pipe wrench, tighten the gauge assembly. Ensure that the pressure gauge face is upright and that the tube elbow is on top.

- Page 10 The bottom of the tubing assembly should connect to the tube elbow in the gauge assembly. The top of the tubing assembly should connect to the tube elbow at the sample outlet of the Welker MPS-2 Micropurge Sample Pump.
- Page 11 Using tubing cutters, remove the excess tubing at the marked point, and then file and smooth the cut edge of the sample probe. 15. The Essentials™ Gas Sampler is now ready to be installed to the pipeline.

7. The Welker IR-7 Instrument Regulator comes factory-set to 50 psig and is equipped with a relief valve pre-set to 85 psig to relieve pressure and protect the equipment in the case of a seal leak or regulator failure. To adjust the regulator setting, loosen the jam nut, and then loosen or tighten the adjusting screw until the regulator pressure gauge reads the desired outlet pressure (Figure 8). -
Page 13: Start-Up Procedures
The inline relief comes factory-set to 1100 psig. The inline relief should not require adjustment unless pipeline pressure drops below 400 psig or maintenance is performed on the inline relief. When sampling into a Welker SC Single Cavity Cylinder, the pressure gauge should read 0 psig at start-up. 5. - Page 14 O-ring in the inline relief may have failed; proceed to Section 3.2, Maintenance. 13. Open the outlet valve on the sample cylinder to relieve test pressure, and then close the outlet valve.

- Page 15 Purging the Sample Cylinder Welker recommends that the sample cylinder be cleaned or purged prior to each sample batch to remove any air and/or old product from the system and prevent cross-contamination between samples. 14. Purge the sample cylinder using the fill and empty method or the continuous purge method as described in Gas Processors Association (GPA) Standard 2166-86, Obtaining Natural Gas Samples for Analysis by Gas Chromatography.

3. All maintenance and cleaning of the unit should be performed on a smooth, clean surface. 4. Welker recommends having the following tools available for maintenance. Please note that the exact tools required may vary by model. a. Adjustable Wrench b. -
Page 18: Maintenance
If maintenance is performed on the MPS-2, the inline relief needs to be reset. Welker recommends setting the inline relief to 1100 psig unless pipeline pressure drops below 400 psig. See Section 3.3, Adjusting the Inline Relief, for instructions on setting the inline relief. - Page 19 When sampling into a Welker SC Single Cavity Cylinder, the inline relief must be set to approximately 100 psig above pipeline pressure. If the inline relief will be adjusted using pipeline product, continue to step 1. If the inline relief will be adjusted using an auxiliary gas supply, proceed to step 9.
- Page 20 Ensure that at least half a turn remains on the spring adjuster, as too much tension will prevent the spring from contracting and releasing when the MPS-2 is actuated. To ensure at least half a turn remains on the spring adjuster, Welker recommends turning the spring adjuster clockwise and counting each turn until the spring adjuster can no longer be turned;...
