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
slide5

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

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.
slide38

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
