Packages · Metering & Analyzer
A sampling system transfers a representative process sample from its take-off point to an analyzer or test point while preserving the properties required by the measurement method. The sample point, phase, pressure and temperature, conditioning, and safe return or disposal are defined from site data and the approved project basis.
From project definition to delivery
Engineering of Sampling Systems concentrates on sample representativeness, transport lag, phase integrity, pressure and temperature conditioning, filtration, calibration, analyzer response, shelter environment and hazardous-area requirements. The selected configuration is verified against normal, minimum, start-up, shutdown and credible upset cases, then checked for operability, maintainability, energy use, process safety and site interfaces before the design is frozen.
The design basis for Sampling Systems is defined from service data, design conditions, and battery limits. For this equipment, Sample take-offs and transport and Sample composition and range must be completed in the datasheet and design documents; performance values and guarantees are set only after the project basis is approved.
Materials, corrosion allowance, sour-service requirements, piping classes, nozzle design, insulation, coating, supports and maintenance access are coordinated with the actual process conditions and project code hierarchy.
Control philosophy, alarms and trips, cause-and-effect logic, interlocks, start-up and shutdown sequences, safe depressurization and operator access are developed consistently from the P&IDs through functional testing.
Battery limits, tie-in points, structural loads, cabling, instrumentation, drains, vents, access routes, lifting envelopes and shipping constraints are controlled through coordinated models and interface drawings.
From project definition to delivery
Proposal quality depends on complete input data and an explicit acceptance basis. The following lists provide a practical starting point and are completed during technical clarification.
Technical Datasheet
These limits describe one heated gas-sampling filter component family and do not represent the complete sample system's guaranteed conditions.
| Parameter | Published value | Basis / secondary data | Application limit |
|---|---|---|---|
| Process pressure / temperature | 50–600 kPa(abs); up to 200 °C | Published operating conditions for one gas-sampling filter family; coated version temperature limit is 180 °C. | Verify probe, seals, materials, corrosion and pressure reference; the complete sample train may have lower limits. |
| Sample flow / filter fineness | 30–500 L/h; 0.3 μm | Flow is stated at 100 kPa and 0 °C; published filter retention is 99.98%. | Flow/retention depend on element, dust loading, pressure drop and sample conditioning design. |
