Rotary gas meters RGK-Ex are designed to measure the amount of gas flowing in the pipeline at operating pressure and temperature. Used for commercial and technological gas accounting.
The meters are designed, manufactured and certified in accordance with recommendations of Ukranian State Standard EN 12480:2006 Rotary gas meters, and Technical regulations for measuring tools, approved by the Cabinet of Ministers of Ukraine No163 dated 24.02.2016 type verification certificate (Module B) № UA.055.ST.044-19.
Flowmeters are explosion-proof and designed to operate together with an electronic gas volume corrector, have the explosion marking «ІІ 2 G Ex ib IIB T3 Gb -25°C≤ Ta ≤ +55°C»,that is confirmed by type verification certificate (Module B) № UA.055.ST.044-19. Link. and compliance with the requirements of DSTU EN 60079 0: 2017, amendment 11: 2017, DSTU EN 60079 11: 2017 and the Technical Regulation of equipment and protective systems intended for use in potentially explosive atmospheres (CMU Resolution of 28.12.2016 № 1055).

i measurment range. This is the Qmin / Qmax ratio, at which the flowmeter operates with relative error not exceeding the the limits of permited values;
Рmax -maximum workking pressure, Mpa Which characterizes body strength of a flowmeter.
Rotary gas meters RGK-Ex are noted: Rotary gas meters RGK-Ex are noted:
RGK-Ex gas meters are installed on the vertical section of the pipeline, gas movement from top to bottom.
No direct sections are required when installing the RGK-Ex gas meter.Operating instructions. Gas counters rotor RGK-Ex.
