IC Card Membrane Gas Meter
The IC card-based membrane gas meter features prepaid functionality and tiered pricing, with the option to add a gas-leak alarm and automatic valve shut-off. It allows users to set multiple billing thresholds and customize various tiered rates, automatically calculating the appropriate discount based on the month’s actual gas consumption. This next-generation smart gas flow meter utilizes an IC card for prepaid payment and automated billing. It is compatible with a wide range of combustible gases, including natural gas, liquefied petroleum gas, and city gas, making it the ideal metering device for modernizing gas management systems. Inside the meter, a low-power 16-bit MCU ensures seamless operation, handling all program functions and data processing automatically. Gas management authorities can remotely manage user accounts via computer—enabling prepaid gas purchases, setting secure IC card passwords, and retrieving real-time data such as remaining gas levels and cumulative usage. Additionally, dedicated management software allows for the creation and maintenance of comprehensive user profiles, storing essential customer information for easy access and tracking.
Core Features
• Fully sealed design: All wiring is completely encased in a high-performance potting compound, with no exposed electrodes. This ensures excellent sealing and guarantees the circuit board can operate reliably over the long term, even in humid or油烟-rich environments.
• Motorized valve technology: Utilizing motorized valve technology for reliable operation and minimal pressure loss;
• Fully sealed design: All wiring is completely encased in high-performance potting compound, with no exposed electrodes. This ensures excellent sealing and guarantees the circuit board can operate reliably over the long term, even in humid or油烟-rich environments.
• Overcurrent detection technology: Automatically detects and shuts off the valve when gas flow in the pipeline exceeds the safe limit.
• Multi-tiered expansion feature: Billing is based on usage amount, with tiered gas rates applied to monthly consumption—this allows for multi-tiered expansion tailored to user needs.
• Supports one-card meter replacement, and the original tiered pricing remains unchanged after the switch;
• Temperature compensation (optional).
