GxS Smart Gas Meters

  • New Smart Meters GxS series combine all the best features and capabilities of previous models :

  • Reliable, resistant to interference, optical pulse readings from measuring unit, using a Gray code wheel

  • Much bettermetrologicalaccuracydue to error curvecorrection

  • Temperaturecompensation

  • Internalshutt-offvalve

  • Volume and Alarmsregistarion

  • Remote safereadingusing AES-128 encryption

  • Wired/Wireless communication EN-13757

NTA8130 + DSMR v.2.2/2.3/3.0


Compact design

  • MID Class 1,5

  • ATEX II 1/2 G Ex ia/ib IIB T3

  • IP-54

  • Over15 battery life time


Temperaturecompensation

Electronic Unithas theabilityto compensate for the effect of temperature on the measurement error.

Temperature correction is performed in a volume of 4 points: -25, 0, +30, +55 C. Between these points, linear interpolation is used

Temperaturesensors


Curve error correction

  • Much bettermeasurmentaccuracy

  • errorsbelow limit ± 0,3% !!!

New Cable Transfer

  • The seals are capable of remaining hermetic after exposure to 820°C

  • The leakage rate of the seal after exposure to 820°C would be better than 1x10-6 cc per sec of helium.


GSU shutt-off valve

  • Safe, internal, build-innewgeneration of ballvalve:

    • Safe open function

    • Lowpressure drop in comparison to competitivedesigns

    • Two state valvepositioncontrol (fullyclosed / fullyopen), confirmed by realiablemicroswitchdesigned to workin gas and oil enviroment

    • Installation on the gas meteroutlet(less contamination)

    • HigherIntrinsicallySafty - usingindustriy field provenstepper motor manufactured by Johnson Electric Group ®

UniSmart: telemetry module

  • Communication

  • Pulsecounting

    • 1 pulse = 1 fullrotation of lastcounterroller(for metersG1,6 - G6 1 puls=10dm3, for meters G10 1 ipuls=100dm3)

    • Algorithm of errorseliminationsuch as errorsdue to mechanicalvibration of rollers in counter.


UniSmart: Functionality

  • The conversion of the volume pulse(m3);

  • Flowshistory (60-dayly, 120-monthly);

  • Alarm registers:

    • Interference by an external magnetic field;

    • Exceeding the maximum flow(Qmax);

    • Lack of pulse.

  • Bootloader (possibility of remote firmware upgrade) under developmentDatagramEncryptionAES-128 acc EN13757-3:

    • OMS (with dynamicinitializationvector);

    • NTA (with dynamicinitializationvector); possible development

    • NTA (withstaticinitializationvector).possible development

  • Power supply: 1x lithiumbatterytype AA;

  • BatteryOperation10 years
