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% !!!
