Product Description

一,Product Description(产品描述)

The STG16-S STS Split-Type Prepaid Gas Meter adopts a combined design of a keypad-type metering main unit and an independent Customer Interface Unit (CIU). Equipped with 300–400m LoRa RF wireless communication capability, it supports seamless balance top-ups, instant consumption queries, and real-time gas usage monitoring. By integrating with a Data Concentrator Unit (DCU), it enables advanced remote management functions, allowing gas operators to remotely supervise metering data, regulate gas distribution, and implement remote on/off control without on-site operations. Specifically engineered for multi-scenario gas metering, the meter features high-precision consumption measurement, making it an ideal solution for accurate billing in residential, commercial (e.g., malls, hotels), and industrial applications.

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.
