GT30XF intelligent flow totalizer adopts ARM chip, supporting pulse/4-20mA flow & Pt100 temp signals. It realizes steam/gas temperature-pressure compensation, stores shift/daily reports, with RS485 Modbus for industrial flow metering.
High-performance ARM Cortex-M3 core, ±0.2%FS high measurement precision
Multi-signal input: pulse, 4-20mA flow, Pt100 temperature and pressure signals
Professional fluid compensation algorithm for steam, natural gas and general gas
Built-in emergency compensation if temp/pressure signals fail to avoid calculation loss
Complete data storage: shift/daily/monthly/annual cumulative reports, power-off logs
USB disk backup for exporting all metering records and configuration parameters
Multiple communication: RS485/RS232 Modbus RTU, supports timing print function
Up to 3 relay alarm outputs for high/low flow, temperature and pressure thresholds
On-screen raw signal debugging view for fast field calibration and troubleshooting
Embedded panel mounting, wide voltage AC/DC power supply for various industrial sites
