Frequently asked questions
Common questions about Itron from 3G Electric.
What are the flow range options for the Itron IGTM-WT turbine gas meters?
The Itron IGTM-WT series offers a range of flow capacities to suit different industrial applications. For example, the G40+65 DN50 model operates from 10 to 100 m³/h, the G100 DN65 covers 13 to 160 m³/h, the G250 DN80 handles 20 to 400 m³/h, the G160+250 DN100 spans 13 to 400 m³/h, the G400 DN100 ranges from 32 to 650 m³/h, the G400+650 DN150 covers 32 to 1000 m³/h, and the G1000 DN150 extends from 80 to 1600 m³/h. These selections allow you to match the meter to your expected flow rates, ensuring accurate measurement within the specified range.
What output options are available on Itron IGTM-WT gas meters?
Itron IGTM-WT gas meters come with dual impulse generator options: 1R1 and HF3. The 1R1 option provides 10 impulses per cubic meter, suitable for low-frequency accumulation and integration with standard counters. The HF3 option delivers 4400 impulses per cubic meter, enabling high-resolution data logging for applications requiring detailed flow analysis. Both outputs can be used simultaneously, allowing connection to separate systems such as a local display and a remote telemetry unit.
What certifications and protection ratings do Itron IGTM-WT meters have?
Itron IGTM-WT meters are constructed from anodized aluminium and are rated IP 65 for protection against dust and water jets, making them suitable for outdoor and industrial environments. They comply with CE marking and the EN 2014/68/EU Pressure Equipment Directive (PED), ensuring they meet European safety and performance standards for pressure-containing equipment. These certifications are important for installations that require regulatory compliance.
How does the modular sizing of Itron IGTM-WT meters benefit procurement?
The modular sizing approach of the IGTM-WT series allows you to independently select the body diameter (DN) and the meter capacity (G-rating). This flexibility means you can choose a meter that closely matches your actual flow range, avoiding oversizing that can lead to reduced accuracy at low flows or undersizing that may cause excessive pressure drop. By selecting the appropriate combination, you can optimize measurement performance and potentially reduce costs associated with meter purchase and installation.
What is the operating principle of Itron turbine gas meters?
Itron turbine gas meters operate on the principle of gas flow driving a rotor mounted inside the meter body. As gas passes through, it accelerates the rotor, and each blade passage generates a pulse that is detected by an impulse generator. The frequency of these pulses is proportional to the flow rate, allowing for accurate volume measurement. This mechanical design provides repeatable performance suitable for fiscal metering and process control applications.
Can Itron gas meters be integrated with SCADA or telemetry systems?
Yes, Itron IGTM-WT meters are designed for integration with external systems. The dual impulse outputs (1R1 and HF3) can be connected to flow computers, SCADA systems, or telemetry units to enable remote monitoring and data logging. The high-frequency HF3 output is particularly useful for applications requiring precise flow data, while the 1R1 output can drive mechanical counters for local readouts. This flexibility supports various data acquisition architectures.
