Key Features & Advantages

Three Parameters in One Meter

Integrated flow, pressure and temperature sensors reduce external instrumentation while enabling automatic operating-condition compensation.

Real-Time Gas Volume Correction

The microprocessor tracks temperature, pressure and compression factor to calculate corrected gas flow continuously.

One-Year Historical Data

EEPROM retains parameters and up to one year of records, protecting settings when power is interrupted.

Flexible Installation and Power

The electronic head rotates 360°, while internal battery or external power options simplify site installation.

Reliable Low-Maintenance Design

No mechanical moving parts reduce corrosion, cleaning and wear; selectable multi-parameter alarm output supports process supervision.
