GAS MICRO NG Electronic Volume Corrector
Next-generation electronic volume corrector for natural gas with smart digital pressure sensors, PT1000 temperature and 4G LTE.
Key Features
- Integral smart pressure transducers (±0.05% reading)
- PT1000 temperature (±0.15% reading)
- Quad-band 4G modem with 3G fallback (Pro/Flow)
- AGA5/7/8, ISO6976 heating-value options
- Modbus RTU/TCP; web-based remote access
- Class I Div 1/2 hazardous-area ratings
- Core / Pro / Flow feature families
Overview
Next-generation electronic volume corrector for natural gas with smart plug-and-play pressure transducers, PT1000 temperature, 4G communications, and Core/Pro/Flow feature tiers. Up to 10-year battery life.
Working Principle
Smart digital pressure sensors (gauge or absolute, 1–100 bara, ±0.05 % of reading) and a 4-wire PT1000 probe (±0.15 % of reading) measure gas conditions, while low/high-frequency pulse inputs count meter volume. The EVC corrects volume using AGA8 (detailed, gross 1/2) or NX19 compressibility and AGA7, and can calculate energy per ISO 6976 or AGA5.
Applications
Benefits
- Up to 10-year battery life (EVC); up to 5 years with cellular reporting twice daily
- Remote diagnostics, configuration and data acquisition over 4G LTE
- Audit trail: 120 months monthly, 365 days daily and hourly
