USAGas Valves & Regulation

Itron manufactures turbine gas meters for industrial flow measurement and custody-transfer applications. The IGTM-WT series comprises modular turbine-meter designs covering DN50 through DN150 body sizes, with flow-range selections from 10 m³/h minimum (G40+65 DN50) to 1600 m³/h maximum (G1000 DN150). Each meter is constructed from anodized aluminium, rated IP 65 for environmental protection, and complies with CE marking and EN 2014/68/EU PED (pressure equipment directive). Output configurations include dual impulse-generator options: 1R1 (10 imp/m³) for low-speed accumulation and HF3 (4400 imp/m³) for high-frequency logging, enabling integration with telemetry, SCADA, and billing systems. The modular sizing approach—where body diameter (DN) and meter capacity (G-rating) are independently selected—allows procurement teams to match flow-range accuracy windows to field conditions without oversizing or undersizing. Turbine-meter operation relies on positive-displacement principles: inlet gas accelerates a rotor inside the meter body; each blade passage generates a pulse captured by the impulse generator. This design delivers repeatability suitable for fiscal metering, process control, and utility infrastructure. Technical specifications—body size, flow range, k-factor assignments, and output pulse rates—are documented per unit to enable direct integration into flow-computer and IoT data-logging deployments.

Common Applications

  • Natural-gas utility billing and custody transfer — Itron IGTM-WT G1000 DN150 for high-volume distribution-network flow measurement.
  • Industrial process gas monitoring — IGTM-WT G250 DN80 or G400 DN100 for boiler fuel, compressed-air, or process-gas consumption tracking.
  • Branch-line and low-flow metering — IGTM-WT G40+65 DN50 for individual facility, department, or pilot-scale gas feeds.
  • Combined custody and operational monitoring — Dual impulse outputs (1R1 for billing, HF3 for diagnostics) on any DN50–DN150 model for split-path data logging.
  • Retrofit and modular system expansion — Modular G-ratings within each DN size allow flow-range tuning without complete meter replacement.

Frequently asked questions

Common questions about Itron from 3G Electric.

What is the difference between the 1R1 and HF3 impulse generators on Itron IGTM-WT gas meters?

1R1 generates 10 pulses per cubic metre (imp/m³), suitable for low-bandwidth data loggers and mechanical counters; HF3 generates 4400 imp/m³ for high-resolution digital acquisition. Both can be specified simultaneously on a single meter. Choose 1R1 for cost-sensitive or legacy systems; select HF3 for SCADA, telemetry, and diagnostic-grade flow trending.

Which Itron IGTM-WT model covers a 32–1000 m³/h range?

The IGTM-WT G400+650 DN150 (SKU COG80020) handles 32–1000 m³/h with a DN150 body. The dual G-rating (400 and 650) indicates capacity-matching flexibility within that flow envelope, supporting both low-load and peak-demand custody-transfer scenarios.

Are Itron gas meters pressure-certified for industrial gas distribution?

Yes. Itron IGTM-WT meters carry CE marking and comply with EN 2014/68/EU PED (Pressure Equipment Directive). Anodized aluminium construction and IP 65 sealing support outdoor and utility-scale deployments. Consult the specific model datasheet for rated working pressure (bar) and material certification details.

What is the smallest Itron IGTM-WT meter available, and what flow range does it cover?

The IGTM-WT G40+65 DN50 (SKU COG80004) is the smallest, rated 10–100 m³/h. DN50 nominal diameter suits low-to-medium process lines and branch metering. Both 1R1 and HF3 outputs are available on this model.

How does anodized aluminium construction benefit Itron turbine meters in the field?

Anodized aluminium resists corrosion from moisture, salt air, and industrial atmospheres, extending service life in outdoor utility and process installations. The material is lightweight, simplifying installation on elevated pipework, while maintaining structural rigidity required for turbine-rotor clearance tolerance.

Can Itron IGTM-WT meters integrate with SCADA and IoT systems?

Yes. The HF3 high-frequency output (4400 imp/m³) enables direct connection to flow computers, data loggers, and SCADA pulse-input modules for real-time volume accumulation and rate trending. The 1R1 output serves cost-effective legacy systems. Pulse format is compatible with standard industrial data-acquisition platforms.
