The T1000 Natural Gas Analyser is designed and developed for demanding conditions and explosive atmospheres. It offers continuous monitoring of fuel gas quality and composition.
The analyser offers superior performance and reliability, yet it is simple and easy to install and operate. Real-time gas analysis data is available on-line and the device can be monitored and serviced remotely.
Typical applications include fuel metering, LNG engine control, natural gas and LNG composition analysis, and boil-off gas analysis.
1. High-Performance Measurement Capabilities
Multi-Component Real-Time Analysis: Capable of simultaneously measuring the concentration of Methane (CH₄), Ethane (C₂H₆), Propane (C₃H₈), Butane (C₄H₁₀), Isobutane (i-C₄H₁₀), C5+, Carbon Dioxide (CO₂), and Nitrogen (N₂) with high accuracy and fast response.
Derived Parameter Calculation: Automatically calculates calorific value (HHV/LHV), Wobbe Index (Gross/Net), density, relative density, methane number, and compressibility factor, complying with ISO 23306:2020 and ISO 6976:2016 standards.
Wide Measurement Range: Supports typical gas concentration ranges of 0–100%, adaptable to different natural gas qualities.
2. Safety and Certifications
Explosion-Proof Certification: ATEX (II 2 G Ex db eb ia IIB T6 Gb) and IECEx certified, suitable for use in Zone 1/2 hazardous areas, ensuring safe operation in explosive atmospheres.
Protection Rating: Housing rated IP66, offering protection against dust and water ingress, suitable for harsh industrial environments.
Fault Diagnosis: Features built-in self-test functionality, real-time monitoring of sensor status, temperature/pressure parameters, and outputs error codes via Modbus registers.
3. System Integration and Ease of Use
Modular Sampling System: Integrates a gas sampling plate including pressure regulation valves, flow controllers, particulate filters, and solenoid valves, supporting automatic switching between sample gas, calibration gas, and nitrogen.
Nitrogen pressure adjustable range: 0–0.5 barg (recommended 0.3 barg), flow rate 1–5 L/min (recommended 1.5 L/min).
Sample gas/Calibration gas pressure adjustable range: 0–0.5 barg (recommended 0.25 barg), flow rate 0.1–0.5 L/min (recommended 0.25 L/min).
Automated Operation: Supports automatic measurement start/stop, automatic zero-point calibration (configurable周期, e.g., every 72 hours), reducing manual intervention.
Easy Installation: Sampling plate dimensions 550 mm × 770 mm × 160 mm (including T1000), designed for wall-mounting with 4x M10 mounting holes.
4. Communication and Control Interfaces
Multi-Protocol Support: Provides Modbus RTU (RS-485) and Modbus TCP/Ethernet interfaces for easy integration into DCS or SCADA systems.
Real-Time Data Access: Read concentration, temperature, pressure, status flags, etc., via register mapping (e.g., addresses 0x0000–0x0046), supporting various data types like floats and strings.
Remote Control: Allows starting/stopping measurements, triggering calibration, controlling relay valves, and downloading historical logs via a service program (Web interface).
5. Maintenance and Reliability
Low-Maintenance Design: Features long particulate filter replacement intervals (up to 12 months with clean gas sources), supporting quick on-site replacement.
Diagnostic Functions: Periodically checks system health status, logs error history (e.g., FPGA communication failure, sensor out-of-range), errors can be cleared via the service program.
Long-Life Design: Core optical components (e.g., Fabry-Perot filter) feature temperature and humidity compensation, operating temperature range -20°C to +55°C, ensuring high stability.
