INFICON IRwin Methane/Combustible Gas Leak Detector: Practical Tips and Operation Guide
Introduction to IRwin
The INFICON IRwin is a portable detector designed for methane and combustible gas leak detection, offering practical tips and operational guidance for gas pipeline network inspections.
Key Features:
- Intrinsically safe explosion-proof design [Ex Symbol]
- Full-range infrared sensor: 1 ppm – 100 vol%
- Integrated GPS
- Built-in gas chromatography for distinguishing biogas and natural gas
- Bluetooth wireless connection [Bluetooth Symbol]
The device features a bright yellow, portable design with a clear digital display showing "0 CH4 PPM".
Section 1: Inspection Equipment
Basic Configuration
The basic setup includes:
- INFICON IRwin methane/combustible gas leak detector.
- 2.5% Natural Gas Standard Gas cylinder (for calibration).
- Telescopic pole with interchangeable probe attachments, such as bell probes and cart probes.
Other Needs
Additional requirements for enhanced functionality include:
- IRwin remote software (accessible via smartphone).
- IRwin App (displaying map overlays for inspection routes).
Section 2: Inspection Operation
The IRwin detector facilitates efficient and accurate gas leak inspections.
- Quick Startup: Less than 1 minute.
- General Mode: Detects from 1 ppm to 100 vol%.
- Recording Process: Work process is recorded via GPS [GPS Symbol] and Bluetooth [Bluetooth Symbol], displaying the inspection path and results.
- Resistance: Withstands high concentration shocks, car exhaust interference, and is non-poisoning.
- Sampling: Features strong suction capability for direct surface sampling.
- Fast Leak Location: Offers rapid response, quick zeroing, and no false alarms.
- Biogas Differentiation: Built-in gas chromatography function distinguishes biogas.
Section 3: Flexible Selection
INFICON offers different kit configurations to suit various needs:
Standard Kit
Includes the IRwin main unit, all detection probes, and accessories, all contained in one case for comprehensive coverage.
Compact Kit
Features the IRwin main unit, a bell probe, and a combined probe pole, designed for efficiency, simplicity, and portability.
Section 4: Equipment Calibration
Proper calibration ensures accurate readings.
Calibration Gas and Regulator
- Adaptive Flow Pressure Regulator (ODFR): Used for adjusting flow and pressure.
- 2.5 vol% Natural Gas Standard Gas: For calibration.
- Mixed Gas: (1% Methane, 50 ppm Ethane, 1000 ppm Propane) - applicable to models with the built-in "Gas Chromatography" function.
Full-range Calibration Mode
- Low Concentration: Air + 2.5 vol%.
- High Concentration: 2.5 vol% + 100 vol%.
Section 5: Distinguishing Biogas
The IRwin detector offers two methods for distinguishing biogas:
Method 1: IR Technology
- Analysis Time: <1 Min.
- Technology: IR sensor ethane analysis.
- Requirements: Requires higher sample concentration.
- Concentration Range: Approximately 3-15 vol% natural gas.
Method 2: Gas Chromatography (GC) Analysis
- Analysis Time: <1 Min (C3 < 4min).
- Technology: GC separation.
- Requirements: Lower sample concentration requirement.
- Concentration Range: >1000 ppm natural gas.
IR ethane analysis can be used as a preliminary rapid screening before GC analysis, offering higher sensitivity and accuracy.
