Natural gas meters

Product catalog summary

Overview: This document provides comprehensive technical specifications, assembly instructions, and maintenance guidelines for various models of natural gas meters, including FN G2.5, FN G4, FN G6, and FN G10. It also details the integration of prepaid module systems with these meters.

General Features: The gas meters are made from deep drawing sheet and coated with electrostatic powder paint. They feature a magnetic transfer system designed to minimize pressure loss and are compatible with natural gas, air gas, and LPG gas. The meters are equipped with a counter structure suitable for prepaid systems.

Technical Specifications: Each model has specific parameters such as flow rates, operating pressure, and temperature ranges. For instance, the FN G2.5 model operates between 0.025m3/h and 4m3/h with a maximum pressure of 0.5 bar.

Assembly Instructions: Meters should be installed in stairwells or external panels, ensuring correct flow direction and counter display height. A check valve is required at the counter inlet, and connections should use stainless flexible hoses and appropriate gaskets.

Maintenance Guidelines: Regular cleaning with a wet cloth is recommended, while external washing is discouraged. Maintenance should be conducted by the manufacturer, and approved filters are advised to extend the device's lifespan.

Points to Consider: Meters should be protected from environmental factors, and electrical devices should be kept at a safe distance. Unauthorized interference can lead to penalties, and proper assembly is crucial to avoid damage during installation.

Performance Data: The document includes error and pressure loss curves for each model, illustrating performance across different flow rates.
