  1. Tczew, XI 2012 r. Smart Metering Development

  2. Smart Metering Development • ContinuedcooperationwithFlonidan A/S in development of GxSlinemeters • UniSmart: Telemetry Module • Automatic Meter Reading • Walk-by and Drive-by systems • Stationary systems • Smart Components Development • Shut-OffballValvewithstepper motor • New Cable Transfer • Modular design of New Metrix EU • New Fields for Cooperation • SecureMeters Ltd. • GWi • Metrixemployeearemembers of: • OMS workgroup • prEN16314 AdditionalFunctionalities WG

  3. 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

  4. Compact design • MID Class 1,5 • ATEX II 1/2 G Ex ia/ib IIB T3 • IP-54 • Over15 battery life time

  5. 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

  6. Curve error correction • Much bettermeasurmentaccuracy • errorsbelow limit ± 0,3% !!!

  7. Evolutioninstead of Revolution From magneticcoupling… … to opticalGray codereading

  17. 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.

  18. 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 ®

  36. 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.

  37. 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
