Sampling Systems for Gas & Moisture Analyzers

Sampling Systems for Gas & Moisture Analyzers

Sample handling systems are essential for getting top performance from your gas and moisture analyzer systems. To get the right sample system for your unique application, turn to GE, the analyzer application expert with more than 40 years of design and construction experience. Couple GE moisture and gas analyzers with off-the-shelf or custom-designed GE sample handling and you’ve got a reliable, accurate, and lowmaintenance measurement system.

 

GE sample systems enhance the performance of an analyzer by providing sample gas to the analyzer at optimal pressure, temperature, flow rate, and cleanliness. Designed specifically for hazardous environments and for use with GE analyzers, GE sample handling systems reduce your cost and downtime by:

 

• Providing better accuracy and reliability of measurement
• Extending analyzer life
• Limiting analyzer maintenance and associated parts and labor
• Facilitating field calibration

Specifications

Wetted Materials Typically 304SS, 316SS, or 316LSS. Components may have glass, viton o-rings, or other wetted materials. Systems
available in Monel and/or 316SS for NACE MR1075 EN3.1.B compliance for natural gas streams with high H2S content.
Sample systems can also be manufactured with PFA tubing and components for acid gas applications.
Isolation Via needle and/or ball valves
Pressure Regulation Via pressure regulators and/or back-pressure regulators. Systems can be supplied with pumps or eductors to pull a gas
sample from a low pressure source.
Temperature Control Enclosed sample panel with insulation may be heated by enclosure heaters (typically explosion-proof) and/or cooled by
air handling systems or vortex coolers, both with thermostat control. Systems in direct sunlight environments may use a
sunshade to avoid radiational heating.
Heat tracing of sample lines from sample tap to sample system panel is within the customer or contractor scope.
Flow Control and Measurement Via needle valves and/or fine metering valves. Displayed measurement via variable area (VA) flowmeters. Alarms via
integral flow switches on VA flowmeters or via separate flow switch component.
Fittings Typically compression type fittings, 1/4 in (6 mm). Custom systems available with VCR® installations for UHP applications
requiring metal-to-metal face sealing components.
Filtration Particulate filtration typical to 7 micron particulate level. Liquid knock-out via coalescing filters, membrane filters, and liquid
dumps.
New Sampling/Sensor Initiative (NeSSITM) Systems available designed to NeSSI (ISA SP76) for certain products.
Quality Assurance GE sample systems are designed and manufactured in accordance with manufacturing site quality policies (typically ISO 9001) and using GE application engineering standard practices. All sample systems are visually inspected for workmanship and to conformance-to-order requirements.
Sample systems may also be inspected against standard drawings or customer-approved drawings, where applicable. All sample systems are pressure tested using dry compressed air and leak detection fluid.
Documentation GE can provide sample system drawings as quoted/built. For complicated projects, an approval cycle is recommended and
system sub-sourcing and construction is typically initiated after receipt of approved drawings. Typical drawing packages include one CAD 2-D outline and dimension drawing with component layout/interconnections plus a BOM (Bill of Material) for each unique sample system design in a particular order.
Factory Acceptance Test (FAT) GE can perform FATs at our manufacturing sites to accommodate customer-specific inspection requirements such as visual inspection, pressure/leak testing, operational performance test, and documentation inspection. FAT requires GE review and acceptance of customer requirements, which usually is done at the inquiry and quotation stage.
