GAS FLOW METERS GFA222, GFA424
GFA222/GFA424 gas meters are the next generation ultrasonic gas flow meters designed to measure the flow rate and volume of natural gas in the forward and reverse direction. The meters have an integrated
flow corrector with pressure and temperature sensors for effective and reliable custody transfer measurements.
The meters comply with the requirements of O IML R137:2012 (w/amend.2014), EN 12405-1:2021, EN12405-2:2012 andt he EU directives MID, ATEX, E MC and PED.
The GFA222/GFA424g as meters ared esigne dw itht ypes of protection “explosion- proof enclosure” d” and” intrinsically safe electrical circuit “i” as per EN IEC 60079-0:2018/AC:2020-02, EN 60079-1:2014/AC:2018-09 and EN 60079-11:2012.
The GFA222/GFA424 meters can be powered by an external 12 VDC source or from in-board battery for autonomous operation. The battery life is not less than 5 years.
The meters have the following outputs: 1 x LF pulse, 1 x LF/HF pulse (user configurable); 1 xR S485 (Modbus); 1 x RS485 (Modbus)/4…20 mA analog output (as ordered).
These meters do not require straight runs.
