skids. Welker products and personnel provide service for the petroleum
and natural gas industry worldwide. Product lines: crude oil samplers,
natural gas samplers, LPG samplers (liquefied petroleum gas samplers) and
LNG samplers (liquefied natural gas samplers). Featured sampling products:
The Welker Composite Gas Sampler, is an extremely accurate sampling device for determining the quality of a flowing stream. It purges itself 100% prior to sample collection and samples are taken at full pipeline pressure. The sampler interfaces with any metering system, is self-contained, intrinsically safe and battery powered, yet sells for only one-fourth the cost of an on-line analyzer. Welker's patented constant pressure Premium Purge Sample Cylinder operates as an integral part of the total sampling system. It provides sample collections, storage and transport of liquid or gas samples at pipeline conditions and can be equipped with mixing capability. The cylinders include a product valve, precharge valve and burst discs. Constant Pressure Floating Piston Sample Cylinders - These Cylinders collect gas or liquid samples at full pipeline pressures, then store and maintain samples at pipeline conditions, regardless of pressure and temperature. For liquids, the cylinders can be equipped with vortex or gravity mixing systems so that there is no loss due to stratification. The cylinders have reliefvalves, gauges and magnetic or rod-type indicators, plus optional purge valves on the product inlet. The patented Welker Light Liquid Hydro-carbon Sampler determines the quality of the flowing stream with highest accuracy. It collects and stores product samples over a given period of time without changing the phase of the sample. With its Vanishing Chamber collection head, which totally voids itself prior to sampling, the sampler allows the product to flow through its body. It is capable of pumping from lowest to highest pressures with no venting to atmosphere. In addition, a patented, pressure-balanced vortex mixer operates either manually or automatically to ensure a proper mixture regardless of how light or heavy the product. The Welker Stack Sampler (patent pending) is a true event sampler in that it operates only when the stack is actuated. Normally installed on emission lines to the stack, the sampler uses a flow generator to create a continuous flow in the system and takes composite samples with the patented Vanishing Chamber head collection method. It samples a full range of products and common pollutants not obtainable from other comparably priced devices. The Stack Sampler can operate under vacuum (with auxiliary supply) or atmospheric pressure. It can sample timed, proportional to flow or on command. Welker Crude Oil Samplers provide proven accuracy to meet API guidelines. In addition to ship loading and off-loading applications, these samplers are used at wellheads and pipeline custody transfer points. The sampler's patented true isokinetic collection head voids itself 100% prior to sampling, ensuring that the sample is consistent with the stream accuracy. The crude oil can then be accurately analyzed to determine BS&W, API gravity, shrinkage and chemical composition. Welker offers a broad selection of components, including various samplers, controllers, containers, and mixing skids. |
