二,Selling Points & Features(卖点特征)

1. Structural & Design Advantages

• Split-type design: Separated metering main unit and independent CIU for flexible installation.
• Compact & lightweight: Aluminum die-casting body with low weight, easy to mount.
• Durable & user-friendly: Flame-retardant casing; independent battery compartment for convenient replacement.
• Reliable protection: IP67 (resists dust and water splashes) and IP65 for open locations (compliant with IEC 60529).

2. Core Functional Features

• Tamper Detection: Automatically closes the valve upon magnetic interference; service restoration requires a dedicated tamper Token.
• Comprehensive Event Log: Records tamper alarms (magnetic/valve events), 10-year consumption data (monthly/hourly), and supports real-time balance/trend queries via short codes.
• Credit Alarming: Triggers alerts when remaining gas credit falls below a user-defined threshold (configurable via Token).
• Emergency Overdraft: Allows emergency gas usage when balance is depleted, with flexible daily/monthly repayment.
• Multi Tariff Support: Enables TOKEN-authorized setup of up to 3 configurable tiered pricing tiers.
• Real-time Clock: High-precision clock ensures accurate timestamps for logged events and scheduled functions.
• Recharge Limitation: Rejects excessive recharge requests when the sum of remaining gas and new recharge exceeds the preset limit.
• Low Battery Alert: Displays a warning for battery replacement; auto-locks the valve (with data backup) if the issue is unresolved.

3. Communication & Interface Advantages

• Long-distance wireless communication: 300–400m LoRa RF wireless communication for stable data transmission.
• User-friendly CIU:
  • ABS material (6.8cm×12cm×2.9cm, 0.1KG) with dot matrix LCD (blue backlight), LED (communication status indicator), and buzzer (for indication/alarm).
  • Dual power supply: AC adapter or 4pcs AA LR6 1.5V dry batteries.

4. Technical Superiorities

• High-precision metering: Adopts international high-end metering chips; measurement error: ±3% for Qmin≤Q<0.1Qmax, ±1.5% for 0.1Qmax≤Q≤Qmax.
• Wide operating range: Working temperature of -10°C ~ +55°C (93% RH @40°C); max working pressure ≤1.0 bar.
• Long battery life: Over 5 years of service life for the meter battery; CIU supports dual power supply for continuous operation.
• Standard compliance: Meets OIML R137-1&2 (Diaphragm) and IEC 62055 (STS) standards; STS-certified numeric Token for secure operations.

5. Vending System Advantages

• Versatile recharge methods: Supports recharge by amount/unit, third-party platforms (M-PESA, Alipay, MTN, Airtel via API), and door-to-door mobile vending.
• Comprehensive data management: Covers meters, prices, customers, regions, sales stations, and accounts (supports creation, editing, querying, Excel import/export).
• Secure account management: Allows password modification, sub-account creation, permission assignment, and clearing of tamper/balance records (with export function).
• Data security & scalability: Backed by Microsoft SQL Server database; supports APIs for personalized function expansion.
• Rich report generation: Produces receipt reports, monthly summaries, customer payment reports, and regional reports for operational analysis.
